DI-1162/DI-1162M Remote Access Router
Introduction
Congratulations on your purchase of a D-Link DI-1162/DI-1162M Remote Access Router. Your new router offers
inexpensive yet complete telecommunications and internetworking solutions for your corporate office, school or
business. It is ideal for everything from Internet browsing to receiving calls from Remote Dial-in Users. It
incorporates the most recent technologies to make fast, secure and stable connections to remote stations via LAN
to WAN and vice versa.
Distinguishing features of the DI-1162/DI-1162M include support for a full range of networking protocols such as
TCP/IP (Transmission Control Protocol/Internet Protocol), Ethernet, Fast Ethernet as well as various other
networking protocols.
Each DI-1162 /DI-1162M router is packed with features that give it the flexibility to provide a complete
networking solution for almost any site. The router fulfills the need for Internet access, IP-based intranetworks and
LAN to multiple WAN communications.
Ease of Installation
The DI-1162/DI-1162M is a self-contained unit that is quick and easy to install. It is designed to be a standalone
unit or it may be mounted on a standard 19-inch networking equipment rack. It uses standard Ethernet wiring to
connect (route) a local area network (LAN) to up to 4 separate wide area networks (WANs) through dial-up or
dedicated, leased lines.
Also included with the router is the DI-1162/DI-1162M Router Configuration Utility, a Windows-based
application that makes configuring the router a snap.
Networking Compatibility
The DI-1162/DI-1162M is compatible with remote access products from other companies such as Ascend, Cisco,
and 3Com. Furthermore, it supports Microsoft Windows 95, Windows 98, and Windows NT remote access
capability.
Product Features
LAN Port
The DI-1162/DI-1162M is equipped with an auto-negotiated 10/100 (Ethernet and Fast Ethernet) RJ-45 jack for
connecting the router to the LAN.
Multiple WAN Ports
The DI-1162/DI-1162M has two EIA-530 WAN ports, each of which can be connected to a dial-up (dial in or out)
line or a dedicated leased line by multiplexing with a modem or CSU/DSU (Channel Service Unit/ Data Service
Unit) respectively. We recommend connecting only one WAN port to the Internet.
Expansion Slot/Modules
The DI-1162/DI-1162M contains an expansion slot able to house any one of the following slide-in expansion
modules:
♦ An RJ-45 10/100 Fast Ethernet port, giving the router another LAN connection.
1
DI-1162/DI-1162M Remote Access Router
♦ Two high-speed serial (async/sync) ports for two additional WAN connections.
♦ A BRI ISDN module (S/T interface only).
These modules allow you to expand the functionality of the DI-1162/DI-1162M to fulfill all your internetworking
needs.
Dial on Demand
The Dial-On-Demand feature allows the DI-1162/DI-1162M to automatically place a call to a remote node, via a
WAN, whenever there is traffic coming from any workstation on the LAN to that remote site.
Full Network Management
The DI-1162/DI-1162M incorporates SNMP (Simple Network Management Protocol) agents and a menu-driven
Network Management System accessible via an RS-232 (console) or Telnet connection.
Security
The DI-1162/DI-1162M supports PAP (Password Authentication Protocol), CHAP (Challenge Handshake
Authentication Protocol), Layer 2 and IP Filtering, and the creation of firewalls.
RIP-1/ RIP-2 Routing Protocols
The DI-1162/DI-1162M supports both RIP-1 and RIP-2 (Routing Information Protocol versions 1 and 2)
exchanges with adjacent routers. These exchanges allow the DI-1162/DI-1162M to send and/or receive routing
tables to adjacent routers in order to streamline WAN communications.
DHCP Support
DHCP (Dynamic Host Configuration Protocol) allows the DI-1162/DI-1162M router to automatically assign IP
addresses to computers as they enter the network. This feature frees the network administrator from assigning and
managing IP addresses for each individual machine on the LAN.
Data Compression
The DI-1162/DI-1162M incorporates the hardware-based Stac LZS Data Compression for CCP (Compression
Control Protocol).
Network Address Translation (NAT/NAPT)
This feature allows multiple users on the LAN to access the Internet (through an Internet Service Provider)
concurrently through a single IP address. This is especially useful for corporate office environments, where a large
number of users need access to the internet, but only a few internet addresses are available.
Applications for the DI-1162/DI-1162M
Some applications for the DI-1162/DI-1162M include:

DI-1162/DI-1162M Remote Access Router
Internet Access
The DI-1162/DI-1162M supports the TCP/IP (a.k.a. IP) protocol, which is the protocol language used for the
Internet. This router allows everyone connected to the LAN to access the Internet.
Internet Security
The DI-1162/DI-1162M can act as a firewall between your office network and the Internet, and can hide the size
of your office network and the host addresses of your office computers from prying Internet users. It can also filter
traffic to and from the Internet allowing only certain types of communications to or from certain locations to pass
through.
Link Branch Offices
The DI-1162/DI-1162M routes communications through its two (upgradeable to four) WAN ports allowing direct
communications to a branch office via phone lines, the internet or both.
Local Routing
The DI-1162/DI-1162M can route traffic between up to eight local IP networks.
Telecommuting
The DI-1162/DI-1162M allows remote users to dial in and obtain remote access to the LAN. This feature enables
users that have workstations with remote access capability, e.g. Windows 95, to dial in using a modem and access
the network resources without physically being in the office.

Rack Mounting
The DI-1162/DI-1162M may stand alone or be mounted on a standard 19-inch equipment rack. Rack mounting
produces an orderly installation when you have a number of related network devices. Use the six supplied screws
to fasten the supplied mounting brackets to either end of the router, then fasten the router into the rack.
Installation and Initial Configuration of the Router
This section discusses the different connections that can be made to the router when setting it up.
Initially, you will only wish to connect the console to the router in order to configure the other ports. Once that is
complete, you will need to turn off the power to the router and plug in the connection cables to the other devices.
Next, power on the other devices. When they have finished powering up, power on the router. Each of these steps
is described in detail in the sections below. Please skip any setting adjustments that do not apply to your
configuration needs.
A Warning about Connecting Cables
It is important that correct cables are used for each connection; otherwise, the router could be damaged.
Before connecting or disconnecting an RS-232 cable between the DI-1162/DI-1162M and the console and
modems, please make sure all devices are off to avoid any chance of damage.

DI-1162/DI-1162M Remote Access Router
Step 1 - Setting up the Console
The initial setup of the DI-1162/DI-1162M requires connecting a console to the 9-pin RS-232 Diagnostic port
on the router’s front panel. A serial cable is supplied with the router in order to make this connection. A
console can be a terminal, such as a VT-100, or a normal PC running terminal emulation software (such as
Microsoft HyperTerminal, included with Windows). The terminal emulation software needs to be configured to
the following parameters:
◊ VT100 terminal emulation
◊ 9600 baud
◊ No parity, 8 data bits, 1 start bit, 1 stop bit
◊ No flow control
Step 2 - Connecting the Console to the Router
A serial cable is included in the DI-1162/DI-1162M package. To connect this cable, plug its nine-pin connector
into the 9-pin RS-232 Diagnostic port on the router’s front panel, then connect the other end to the serial port on
the rear of your computer or data terminal.
Please make sure both machines are turned off before making this connection.
After the connection is made, first power on the console. If you are using a PC, run the terminal emulation
software at this time. After the PC and the terminal emulation software are up and running, power on the router.
Using the Console
The Console Program is the interface that you will be using to configure your DI-1162/DI-1162M. Several
operations that you should be familiar with before you attempt to modify the configuration of your router are listed
below:

next chapter, “Configuration and Management.”
At this point, please proceed to the next initial configuration step.
Step 3b - Configuring the WAN Ports for Dial-in, Dial-out and Leased Lines
Please configure LAN port as described above to familiarize yourself with the configuration program (the LAN
port must be configured in any case). Some settings that were made configuring the LAN will be repeated below.
Please disregard the instructions below if the setting has already been changed.
10
DI-1162/DI-1162M Remote Access Router
Each WAN port can be configured to either receive dial-in calls (act as a Remote Access Server), dial out to other
routers (at branch offices or the Internet, for instance), or both (but not at the same time). The WAN ports can also
be configured for a leased line (synchronous) connection. Please note however that we recommend only one single
WAN connection to the Internet since a second connection will not significantly enhance the performance of the
connection.
Enabling a WAN Port
In this section, we will use WAN1 as an example. Other WAN ports however, will follow the same procedures.
1. The WAN port must be enabled in the Interface Configuration submenu.
♦ Choose Interface Configuration!WAN 1.
♦ Configure the Protocol setting. This is a very important setting as it determines what type of device can be
connected to the WAN port.
◊
◊
◊
SLIP Asynchronous mode used for modems.
PPP_ASYN Asynchronous mode used for modems.
CISCO_HDLC Synchronous mode used for CSU/DSU’s or synchronous modems
using a leased line.
◊ PPP_SYN Synchronous mode used for CSU/DSU’s or synchronous modems using a
leased line.
◊ FRAME_RELAY A high-speed protocol available from many ISPs for switched lines.
The current version of this router only supports IP over frame relay and PVC. OSPF,
IPX, and bridge are not supported.
♦ Position the cursor over the State item and press <space bar>. The State will change from Disable to

detailed explanations concerning the nature and use of these items.
♦ Position the cursor on the Save option at the bottom of the screen and press <Enter> to save the new
setting.
♦ Choose Exit in the submenus to return to the Main Menu.
Configuring for Dial-in, Dial-out or Leased Line
At this point, you need to decide if the WAN port will be used for dialing in, dialing out, both or a leased line
connection. The settings you make in next few steps depend on how you wish to use the WAN port. Remember,
only one WAN port should be setup to connect to the Internet.
4. Configure the Dial settings in the Advanced Functions submenu.
♦ Choose Advanced Functions!Dial Configuration.
♦ Choose WAN1.
♦ Please refer to the “Configuration and Management” chapter of this manual for more detailed information
regarding the items in this screen.
♦ Position the cursor on the Save option at the bottom of the screen and press <Enter> to save the new
setting.
5. Define and configure dial-in users who may access the router and the LAN it is connected to (if applicable).
♦ From the Main Menu choose Advanced Functions!Remote Access Configuration!Dial-In User
Profile and press <Enter> in the first empty field.
♦ Enter the dial-in user’s Username (this might not be their real name) and Password.
♦ Change the State to Enable.
♦ Please refer to the “Configuration and Management” chapter of this manual for more detailed information
regarding the items in this screen.
♦ Position the cursor on the Save option at the bottom of the screen and press <Enter> to save the new
setting.
The WAN port is now setup to receive calls from that user. At this point, you may wish to define other users
who will dial-in to the router. Please note that User Profiles for dial-in users are valid for any WAN port
configured to receive calls.
6. Define a WAN port for dialing out.
♦ From the Main Menu choose Advanced Functions!Remote Access Configuration !Remote Network
Profile and press <Enter> in the first empty field.
♦ Set the Direction to In, Out, or Both.
♦ Enter a Name and Password used to establish Incoming and/or Outgoing connections (if the remote site
uses PAP or CHAP).

12
DI-1162/DI-1162M Remote Access Router
♦ Change the State to Enable.
♦ Please refer to the “Configuration and Management” chapter of this manual for more detailed information
regarding the items in this screen.
♦ Position the cursor on the Save option at the bottom of the screen and press <Enter> to save the new
setting.
♦ Choose Exit in the submenus to return to the Main Menu.
7. Define a WAN port for a leased line connection.
♦ There are only three steps that need to be done to configure a WAN port for using a leased line and they
have already been done. They are numbers 1, 2 and 3; enabling the WAN port in the Interface
Configuration submenu, configuring the Protocol setting to a synchronous mode, and assigning an IP
Address to the WAN port in the Network Configuration submenu. Remember to save any submenu
screens in which you have made changes.
Choose LOGOFF from the Main Menu.
Your WAN ports are now configured and should operate normally. Please note that many of the settings
configured here depend on the type and capabilities of the device being connected.
At this point in the installation process, you need to turn off the router. Don’t worry. As long as you saved each
screen in the configuration process, your settings will have been saved in the EEPROM and will not be lost.
Step 4 - Connecting the Router to a LAN
Your DI-1162/DI-1162M has a single LAN port for connecting to an Ethernet or Fast Ethernet switch or hub.
The jack for the router’s Ethernet port is of the type known as EIA RJ-45. The cabling used should be Category 3,
4 or 5 UTP or STP depending on the connection speed, fitted with an RJ-45 connector.
The 10/100M auto-negotiation feature allows this port to automatically configure itself to match the settings used
by the port it is being connected to. If it is connected to another 10/100 Fast Ethernet capable port, the two ports
will configure themselves to attain the best connection possible.
Full duplex mode will only be enabled if this port is connected to a full-duplex capable switched port.
At this point, please connect the router to the LAN.
Step 5 - Connecting the Router to WAN Devices
The DI-1162/DI-1162M has two DB-25 ports corresponding to WANs 1 & 2. These two WAN ports are both
synchronous/asynchronous ports, and can connect to a modem or CSU/DSU using a standard serial cable with a
DB-25 connector at one end.
Make sure both the WAN device(s) and the router are turned OFF when making these connections.
Step 6 – Plugging in All Devices
Plug the 100 ~ 240V AC/DC power cord into the power jack on the router’s rear panel and into a power strip or
grounded wall outlet.
At this point in the installation, you may plug in and power on all other devices. Do not power on the router yet.
13
DI-1162/DI-1162M Remote Access Router
Step 7 - Powering Up the DI-1162/DI-1162M
After all the devices are powered up, the DI-1162/DI-1162M can be turned ON. The router will perform a POST
(Power-On Self-Test). It is during this POST procedure that the PROM Configuration Menu can be accessed.
The router is now able to use the LAN and WAN ports.
The router must be further configured for managing your network. This can now be done by using the console, the
included Windows-based Configuration Utility, or Telnet.
For more information about configuring or managing the router, please refer to the next chapter, “Configuration
and Management.”
14
DI-1162/DI-1162M Remote Access Router
Configuration and Management
After the initial startup (POST) test, the router will prompt you for login and password. This is the opening page of
the router’s configuration program, called the Console program. The Console program is stored in the Flash
memory chips in the router and the settings are written in EEPROM chips in the router. It is the most basic level
for configuring and managing the router and the network to which it is connected.
If you’re starting the router for the first time, the default login and password is “Admin” – the login and password
are case-sensitive, alphanumeric characters.
Note that once you are in the Main Menu, if there is no activity for more than 5 minutes, the router will
automatically log you out. Your first endeavor should be to increase the ‘timeout’ time by adjusting the
appropriate value in the System Information submenu.
The router can also be configured remotely through a LAN or WAN connection by using the included Router
Configuration Utility or Telnet. However, if you wish to do this, the console program must first be used to initially
configure the relevant port on the router. Please see Step 3 - Initial Configuration of the Router on page 8 of this
manual for more detailed information.
Console Program Main Menu
The Main Menu is shown below.
15
DI-1162/DI-1162M Remote Access Router
As mentioned earlier, your first endeavor should be to increase the automatic timeout. Enter the System
Information to do this. You will see this screen:

♦ System Contact – Enter the name of the department or individual responsible for maintaining the router.
♦ System Name – Give the router a descriptive name for identification purposes.
♦ System Location – Enter the physical location of the router.
♦ Console/Telnet Display Timeout in Minutes – This is a security measure to automatically logoff from the
console menu after a given idle time. Enter a timeout time between 0 and 90 minutes. Zero specifies no
timeout.
♦ System MAC Address –The physical address of this router.
♦ External MAC Address – The physical address of the external LAN add-in module, if present.
Interface Configuration
Under Interface Configuration in the main menu is the following Interface Configuration screen, used to
configure the interfaces for the LAN(s) and two WANs:
17
DI-1162/DI-1162M Remote Access Router
LAN
The parameters are described below:
♦ Description – This is a user-defined, 32-character identifier used to name the LAN.
♦ Operation Mode – The LAN port is automatically set to auto-negotiation. When connected to another LAN
port, 10/100 Fast Ethernet will configure this port to match the settings of the other LAN port. If the other port
also implements 10/100 Fast Ethernet, the two ports will auto-negotiate the best possible settings achievable by
both ports.
♦ State – This is a toggle, to Disable or Enable the LAN interface.
18
DI-1162/DI-1162M Remote Access Router
WAN
The parameters are described below:
♦ Description – This is a user-defined, 32-character identifier used to name the WAN.
♦ Modem Init String – This parameter is valid only for asynchronous connections. It is a user input AT
command string to initialize a modem or ISDN TA attached to the WAN interface. Please refer to your WAN
device’s handbook for more information about using initialization command strings.
The default setting is for Hayes-compatible asynchronous modems and is AT&FS0=1X1, where:
AT–
The mandatory first two characters of an AT command string.
&F–
Initializes the modem to its default settings.
S0=1– Sets the modem to auto-answer.
X1 –
Displays the established connection speed to the dial-in user (e.g. Connection established at 56.6
kps).
♦ Protocol – This is a protocol used to encapsulate IP messages over synchronous and asynchronous serial links.
The device being connected to must be using the same protocol for a connection to succeed. The five protocols
are described:
1.
CISCO_HDLC – This is a serial line encapsulation method for transmitting datagrams over synchronous
serial point-to-point links.
2.
SLIP – Serial Line Internet Protocol. A serial line encapsulation method for transmitting datagrams over
asynchronous serial point-to-point links. If linking the router to a computer, each end must know the other’s
IP address.
3.
PPP_SYN – This serial line encapsulation provides a method for transmitting datagrams over synchronous
serial point-to-point links. Unlike the SLIP protocol, PPP can determine the IP address configuration
automatically.
19
DI-1162/DI-1162M Remote Access Router
4.
PPP_ASYN – This serial line encapsulation provides a method for transmitting datagrams over
asynchronous serial point-to-point links. Unlike the SLIP protocol, PPP can determine the IP address
configuration automatically.
5.
FRAME_RELAY – This serial line encapsulation provides a method for high speed transmission of
datagrams over dedicated lines. We currently only support PVC.
♦ Phone Number – This is only a reference field, used to contain your line’s phone number when using an
asynchronous dial-in modem.
♦ Inbound Authentication – This defines the authorization protocol that will be used when accepting a dial-in
connection. The choices are Password Authentication Protocol [AUTH_PAP], Challenge Handshake
Authentication Protocol [AUTH_CHAP] or None. AUTH_PAP and AUTH_CHAP do not provide a screen for
users to manually enter their Username and Password – instead, this data must be entered into the dialing
software before placing the call. Make sure the device dialing in is using the same protocol as defined here.
The None setting may be used when you do not wish dial-in users or networks to identify themselves or be
subject to security.
♦ Baud Rate – This parameter must be set to configure the communication speed for asynchronous
communication devices (modems). Please refer to the communication device’s handbook to get the proper
setting.
Available synchronous communication device speeds are: 9600, 19200, 38400, 64K, 128K, 256K, 512K, 1M,
1.544M, and 2M baud. Available asynchronous communication device speeds are: 9600, 19200, 38400, 57600,
and 115200.
For synchronous connections, the router will automatically match the clock speed of the device being
connected.
♦ State – This is used to Disable or Enable this interface.
♦ Frame Relay Config . . . – Highlight this item and hit <Enter> if FRAME_RELAY is selected as the Protocol
above and then complete the WAN Frame Relay configuration settings on the screens described below.
20
DI-1162/DI-1162M Remote Access Router
WAN Frame Relay Config
This screen allows you to specify which WAN 1 or WAN 2 Frame Relay is to be configured by highlighting the
desired entry below and then hitting <Enter>. Next, enter a Data Link Connection Identifier (DLCI) between 16
and 991 and Enable it in the State field on the following screen. Additionally, you must choose the appropriate
Switch Type on the WAN Frame Relay Config screen below to complete the WAN Frame Relay configuration.
The parameter is described below:
♦ Switch Type – This allows you to choose Local Management Interface (LMI) specification. Currently, we
support ANSI T1.617 Annex D and ITU Q.933 Annex A specifications. This switch type must be configured to
match your Frame Relay subscription. Once a change has been made, the router must be rebooted.
21
DI-1162/DI-1162M Remote Access Router
The parameters are described below:
♦ DLCI(16. .991) – This Data Link Connection Identifier is used to match your Frame Relay subscription..
♦ State – This is a toggle, to Disable or Enable the WAN interface.
Network Configuration
There are three items on the Network Configuration menu: (Bridge Configuration and IPX Configuration appear
on DI-1162M only):
22
DI-1162/DI-1162M Remote Access Router
IP Configuration
IP networking and router advertisement are enabled on the IP Configuration screen:
The parameters are described below:
♦ IP Networking – The IP Networking function can toggle to connect/disconnect this router from the entire IP
network. When IP Networking is disabled, all routing functions are stopped. The only IP Address the router
will act on is it’s own, via Telnet for example.
♦ Router Advertisement – When this option is enabled, the router will periodically send out ICMP packets that
announce itself on the network. These ICMP packets are utilized by the Windows 98 or later operating system,
which will automatically update the default gateway setting on the computer in which it is installed.
IP Stack Configuration
The network interface IP address, mask and protocols are specified in the IP Stack Configuration submenus.
Choose the desired interface from the IP Stack Configuration menu below:
23
DI-1162/DI-1162M Remote Access Router
Below, the submenus for both the LAN and WAN interfaces are shown.
24
DI-1162/DI-1162M Remote Access Router
The parameters are described below:
♦ IP Address – This is the IP address for the router on the network to which this interface is connected.
♦ Netmask – This is a 32-bit bit mask that shows how the IP address is to be divided into network, subnet and
host parts. The netmask has ones in the bit positions in the 32-bit address which are to be used for the network
and subnet parts, and zeros for the host part. The mask should contain at least the standard network portion (as
determined by the address's class), and the subnet field should be contiguous with the network portion.
♦ Forwarding (LAN) – This enables or disables communications between this interface and other router(s) on
the LAN.
♦ State (WAN) – This is a link method between this interface and adjacent router(s). The methods are described
as follows:
1.
Auto – This obtains and utilizes the IP address assignment from your ISP (Internet Service Provider).
2.
Disable – This disables this interface.
3.
IP Stack – This enables this interface, and the IP address used will be the value of the parameter, IP
Address.
4.
Unnumber – This utilizes a method of connecting this router with adjacent routers, without having to
define an IP network prefix between them. The adjacent routers must have Unnumber capability, too.
♦ RIP Routing Protocol – This is a distance vector routing protocol. RIP is an Internet standard Interior
Gateway Protocol defined in RFC 1058 and RFC 1723. Routing information is sent periodically (each 30
seconds, or triggered by topology change) to an adjacent router. The adjacent router must be using the same
protocol. Setting this to RIPV1&V2 will give the router the ability to make routing information exchanges with
any adjacent router.
♦ RIP Routing Mode – This parameter allows the router to specify the extent to which it partakes in the RIP on
this port. The options are described below:
1.
None – The router will not participate in any RIP exchange with adjacent routers.
2.
Listen – The router will incorporate routing information from adjacent routers, but will not send it’s own
routing table.
25
DI-1162/DI-1162M Remote Access Router
3.
Talk – The router will send adjacent routers it’s own routing table, but will not incorporate routing
information from them.
4.
Both – The router will incorporate routing information from adjacent routers, and will send adjacent
routers it’s own routing table.
♦ IP Multicasting – This feature enables or disables the router’s ability to perform IP multicasting. When
enabled, the router will perform IGMP. It can also perform DVMRP if this feature is enabled below.
♦ Multicast Protocol – If this parameter is set to None, the router will only use the Internet Group Management
Protocol (IGMP). If it is set to DVMRP, the router will also use the Distance Vector Multicast Routing
Protocol (DVMRP).
♦ IGMP Version – Configures the router to use either IGMP version 1 or 2.
♦ DHCP Client (LAN) – This feature allows the LAN port to be assigned an IP address from a DHCP server
other than the one in the router. This feature should be enabled only for special configurations (such as the
presence of a cable modem on the LAN) where you wish the router to work with a device on the network that
must act as a DHCP server. Otherwise, this feature should be kept disabled.
♦ RIP Spoofing (WAN) – This feature should only be enabled if you have more than one router on your network
and this router is providing your WAN connection. In this case, if the WAN connection is dropped due to
inactivity and this feature is enabled, RIP packets will be sent to the other routers on the network telling them
that data can still be sent to the WAN via this router. Otherwise, the other routers will learn that the WAN link
has been disconnected and will no longer forward packets destined for the WAN to this router, causing the
packets to be dropped before Bandwidth on Demand has a chance to reestablish the WAN connection.
WAN Frame Relay IP Config
If FRAME_RELAY is selected for the Protocol on WAN 1 or WAN 2 under Interface Configuration, the
following screen will appear:
The descriptions for all the fields are the same as in the previous section. Select one of the Frame Relay IP Config
items at the bottom of the screen to access the following screen:
26
DI-1162/DI-1162M Remote Access Router
The descriptions for all the fields are the same as in the previous section.
IP Static Route
A static route is a permanent entry in the routing table. Static routing provides a means of explicitly defining the
next hop router for a particular destination network IP address. Each static route entry also allows for a metric
(a.k.a. hop count) to be specified.
The parameters are described below:
27
DI-1162/DI-1162M Remote Access Router
♦ IP Address – This specifies the destination network IP address (or a host, depending on the netmask) and pairs
it with a gateway.
♦ Netmask – This mask shows how the destination IP address is to be divided into network, subnet and host
parts. The netmask has ones in the bit positions in the 32-bit address which are to be used for the network and
subnet parts, and zeros for the host part.
♦ Gateway – This is the adjacent next hop router, for which the packets, arriving to this router with this
destination IP address, will be forwarded.
♦ Hops – This is an associated RIP metric that may have its value set between 1 and 15, inclusive. A metric
value higher than 15 (such as 16) means that the network is unreachable.
♦ Intf – This is the network interface containing the gateway that the packets will be forwarded through.
♦ State – This enables or disables a particular entry.
IP Static Route Examples
The IP Static Route Table shown in the example IP Static Route screen above has the first three entries configured
for common implementations of static routing.
The first entry assumes that WAN1 has a connection to the Internet and defines the default next hop router. If you
use this router to connect to the Internet it is very important that you create an entry here that defines the default
next hop router as your ISP. This configuration is also commonly used when RIP exchanges with other Internet
routers (on WAN1) are disabled.
The second entry shows how to configure static routes when there is another router on the LAN. The IP Address
shown (202.12.125.0) is the network address for a branch office, for example. The Gateway Address
(210.172.23.1) is the IP address to the LAN port on another router on LAN1 that maintains a WAN connection to
the branch office.
The third entry is an example of an enterprise WAN connection (through telephone lines) to another router, at a
branch office for example. The IP Address is the network address of the branch office. The Gateway Address is
the IP Address of the WAN port on the branch office router. This configuration assumes there is a modem on
WAN2 maintaining a dial-up connection to the branch office.
OSPF Configuration
Open Shortest Path First (OSPF) is a link-state routing algorithm that provides more control over the routing
process and responds faster to changes as compared to distance-vector routing. OSPF routing table updates only
take place when necessary rather than at regular intervals, thereby reducing traffic and saving network bandwidth.
The OSPF Configuration screen below allows you to specify an OSPF Router ID, determine As Border Router
status, and Enable OSPF under State. Currently, OSPF over frame relay is not supported.
28
DI-1162/DI-1162M Remote Access Router
The parameters are described below:
♦ OSPF Router ID – This is a 32-bit number that uniquely identifies the router in the Autonomous System. If
the OSPF Router ID is not configured, the router will automatically choose LAN 1’s IP as the OSPF Router
ID.
♦ AS Border Router – Setting to allow DI-1162/DI-1162M to act as Autonomous System Border Router. As an
AS Border Router, the router can import and export routing information of other Autonomous Systems, such as
RIP.
♦ State – Toggle between Enable and Disable.
OSPF Area Configuration
Select the desired OSPF Router ID to either make changes to or configure for the first time on the OSPF Area
Configuration screen (in which case, the five entries will be blank and all you need to do is press <Enter>.
29
DI-1162/DI-1162M Remote Access Router
Complete the OSPF configuration information on the screen below:
The parameters are described below:
♦ Area ID – Enter the OSPF Area ID number in this field.
♦ Authentication Type – Toggle between None and SimplePasswd.
30
DI-1162/DI-1162M Remote Access Router
♦ Stub Area – Toggle between Yes and No. AS external advertisements are not flooded into/throughout stub
areas. Routing to AS external destinations in these areas is based on (per area) default only.
♦ Stub Default Cost (0. . 255) – Enter a Stub Default Cost between 0 and 255 in this field.
♦ State – This enables or disables a particular entry.
♦ Address Ranges – Enter the Range Net, Range Mask, Advertisement status, and Enable the State of up to five
OSPF entries in these fields. This allows users to manually enter OSPF subnet information. Range Net and
Range Mask describe the collection of IP addresses contained in the range. Networks and hosts are assigned to
an area depending on whether their addresses fall into one of the area’s defining address ranges.
Advertisement is set to either Yes or No. Routing information of these address ranges is advertised external to
the area if and only if such status is set to Yes.
OSPF Intf. Configuration
Select the desired interface on the OSPF Intf. Configuration screen:
Complete the OSPF interface configuration information on the screen below:
31
DI-1162/DI-1162M Remote Access Router
The parameters are described below:
♦ Area ID – Enter the OSPF Area ID number in this field.
♦ Output Cost (0 . . 65535) – The cost of sending a packet on the interface, expressed in the link static metric.
This is advertised as the link cost for this interface in the router’s router links.advertisement. The interface
Output Cost(s) must always be greater than 0.
♦ Router Priority (0. . 255) – This number determines priority when two routers attached to a network both
attempt to become the Designated Router. The router with the highest priority takes precedence.
♦ Hello Interval (1. . 65535) – The length of time (in seconds) between the Hello Packets that the router sends
on the interface. This value is advertised in the router’s Hello Packets. It must be the same for all routers
attached to a common network. The smaller the Hello Interval, the faster topological changes will be detected,
but more OSPF routing protocol traffic will ensue.
♦ Dead Interval (1. . 65535) – After ceasing to hear a router’s Hello Packets, the number of seconds before its
neighbors declare the router down. This should be some multiple of the Hello Interval. The value must be the
same for all the routers attached to a common network.
♦ Authentication Key – This configured data allows the authentication procedure to generate and/or verify the
authentication field in the OSPF header. This value must be the same for all routers attached to a common
network.
♦ State – This enables or disables a particular entry.

Bridge Configuration
Bridges are enabled on the Bridge Configuration screen:
The parameter you can set is described below:
♦ Bridge Enable – The third option on the Bridge Configuration menu allows you to enable or disable
bridging. Press SAVE once you are finished
34
DI-1162/DI-1162M Remote Access Router
Bridge Settings
The parameters are described below:
♦ Bridge ID – The Bridge ID is a read-only object composed of the bridge priority and the MAC address. So in
the screen above, the Priority is 32768 and the MAC address is zero since it was yet to be entered.
♦ Priority – A Bridge Priority is a read-write object that can be set from 0 to 65535. This is the priority number
of the bridge. The value is used in conjunction with the bridge MAC address to set the bridge ID, which in turn
is used when determining the root bridge of a multi-bridged network. The root bridge is responsible for
processing data packets when network loops occur. The smaller the number set, the higher the bridge priority
is. The higher the bridge priority, the more chance the bridge has of becoming the root bridge. Zero is the
highest priority.
♦ Port Aging – This is a read-write object that allows you to set the aging time for MAC addresses in a port’s
address table. When the time-out figure is reached, the bridge will remove the MAC address.
♦ Max Age – Maximum Age is a read-write object that can be set from 6 to 40 seconds. At the end of the
Maximum Age, if a BPDU has still not been received from the Root Bridge, your Switch will start sending its
own BPDU to all other switches for permission to become the Root Bridge. If it turns out that your Switch has
the lowest Bridge Identifier, it will become the Root Bridge.
♦ Hello Time – Hello Time is a read-write object that can be set from 1 to 10 seconds. This is the interval
between two transmissions of BPDU packets sent by the Root Bridge to tell all other switches that it is indeed
the Root Bridge. If you set a Hello Time for your Switch, and it is not the Root Bridge, the set Hello Time will
be used if and when your Switch becomes the Root Bridge.
♦ Forward Delay – The Forward Delay is a read-write object that can be set from 4 to 30 seconds. This is the
time any port on the Switch spends in the listening state while moving from the blocking state to the forwarding
state.
Bridge Port Setting:
35
DI-1162/DI-1162M Remote Access Router
♦ Priority – Port Priority is a read-write object that can be set from 0 to 255. The priority is used to determine
the designated port if the Path costs of redundant switch to switch connections are the same. The higher the
port priority, the more chance the port has of becoming the designated port. Zero is the highest priority.
♦ Cost – Path Cost is a read-write object which is the first consideration when deciding on a designated port for
switch to switch connections.
♦ Bridged – Select the desired group.
Static Bridge
The parameters are described below:
♦ MAC Address – This is the MAC address of the network host, or node, that you wish to statically bridge.
♦ Interface – This designates the specific interface, either LAN, one of the ISDN interfaces, or Dial-In.
♦ State – This enables or disables a particular entry.
IPX Configuration
If you are working on a Novell network, you may want to set up IPX routing. IPX (Internetwork Packet eXchange)
is the routing protocol used in Novell networking environments.

transmitting system to a receiving system.
♦ IPX SAP – Enable IPX Service Access Protocol (SAP) to disseminate information about network services and
their addresses to all nodes in an IPX network.
♦ NCP watchdog spoofing – Enable this for Dial On Demand. Novell defines special packets to send and check
to see if each side of the connection is fine. This minimizes the number of unnecessary packets sent through the
Internet.
♦ Type 20 Broadcast – Enable this if NetBIOS requires forwarding by the router. Type 20 Broadcast must be
enabled on both ends for this function to work.
♦ State – This enables or disables a particular entry.
38
DI-1162/DI-1162M Remote Access Router

was reached. The number of hops is part of each network entry in a RIP packet.
♦ Interface – Select the desired interface.
♦ State – This enables or disables a particular entry.
SNMP Agent Configuration
The Simple Network Management Protocol (SNMP), defined in STD 15, RFC 1157, is a protocol governing the
management and the monitoring of IP network devices and their functions. The DI-1162/DI-1162M supports the
use of SNMP to acknowledge communication between management stations and itself. Basically, the DI-1162/DI1162M, when connected to the network, acts as an SNMP agent, a software process that responds to queries using
SNMP to provide status and statistics about the router.
Following is a description of how to configure the DI-1162/DI-1162M for SNMP management.
The parameters you can set is described below:
♦ SNMP Authenticated Trap – You can Enable or Disable an authentication failure trap message being sent to
the Management Station by the router. When an SNMP packet with an invalid community name is received, it
will be dropped. If this parameter is enabled, a trap will be sent to the network manager; if this parameter is
disabled, no trap will be sent.
41
DI-1162/DI-1162M Remote Access Router
SNMP Community Configuration
Select and enter the SNMP Community Configuration submenu. You will see the following configuration
screen:
The parameters are described below:
♦ SNMP Community String – This community string is a user-defined identifying name used to group together
some arbitrary set of SNMP application entities managed by the network manager.
♦ Access Right – This element of the set (Read Only, Read/Write) is called the SNMP access mode. If the
SNMP Community String has an Access Right of Read/Write, then that Community String is available as an
operand for the get, set, and get next operations. Otherwise, if the Community String’s corresponding Access
Right is Read Only, then it is available as an operand for the get and get next operations only.
♦ Status – This validates or invalidates the use SNMP Community String, by setting the string to Valid or
Invalid. Note that setting the use of the string to Invalid is the same as removing the string, however, the string
remains so as to be validated at an appropriate time.
SNMP Trap Manager
From the SNMP Agent Configuration menu, select and enter the SNMP Trap Manager submenu. You will see
the following configuration screen:
42
DI-1162/DI-1162M Remote Access Router
The parameters are described below:
♦ IP Address – Enter the IP address of the host who will act as an SNMP Management Station. The DI-1162/DI1162M router will send SNMP traps to these addresses.
♦ SNMP Community String – The community string is a user-defined identifying name used to group together
some arbitrary set of SNMP application entities managed by the network manager. Traps will be sent to the IP
Address (previous parameter) as long as the corresponding Community String, in the Management Station’s
trap manager software, is the same.
♦ Status – This validates or invalidates the use of the SNMP Community String, by setting the use of the string
to Valid or Invalid. Note that setting the string to Invalid is the same as removing the string, however, the
string remains so as to be validated again at an appropriate time.
Advanced Functions
The Advanced Functions menu holds most of the more complex configuration settings and is shown below:
43
DI-1162/DI-1162M Remote Access Router
Remote Access Configuration
The Remote Access Configuration menu is used to set up the router for dial-in and dial-out connections through
modems and/or ISDN devices attached to the WAN ports. The two B channels on the ISDN line or two modems,
one connected to each WAN port, can support two independent remote connections or be banded together using
Multi-link PPP to implement Bandwidth on Demand (configured separately in the PPP Configuration menu, the
last item in the Advanced Functions window).
Remote Operation Overview
The DI-1162/DI-1162M is very flexible and can be configured for a variety of remote connections. Since
configuring the router can be quite complex - depending on the number and type of remote connection(s) you wish
to implement – we have described some of the basic functions and procedures below.
Dial-In User Connections
Dial-in users are defined as a single user on a computer, such as a person working at home, who dials into the
office to use network resources. In almost all cases, a Dial-In User Profile needs to be set up for each user who will
dial in to the router so the router can tailor the connection for each user. Once this is done, the remote user will be
able to use network resources as if he were connected locally. When the user dials into the DI-1162/DI-1162M, the
call comes into the WAN port and after answering the phone, the DI-1162/DI-1162M:
1. Identifies the Username and Password using the authentication protocol defined in the Interface
Configuration!WAN submenu. The dial-in user is not prompted for this information, but must enter it into
his dialing software before dialing.
2. Checks the Username and Password against those defined in the Dial-In User Profiles and Remote Network
Profiles.
3. Assuming a matching Dial-In User Profile is found, the router may configure the IP address of the remote
station (as defined in the Dial-In User Profile).
4. Configures a dial-in Interface (a virtual circuit) to handle the connection.
5. Establishes the connection.
44
DI-1162/DI-1162M Remote Access Router
6. In the case where the Dial-In User does not need to supply a Username and Password (Auth Type is set to
None in the Interface Configuration submenu) the remote computer must have its own IP address.
Remote Network Connections
Remote networks are defined as other networks (LANs) that have WAN connections using a router, Internet
server, network modem or similar device (in this document however, we will assume the remote device is a
router). In almost all cases, a Remote Network Profile needs to be set up for each network that will connect to the
DI-1162/DI-1162M via a WAN connection. The Remote Network Profiles are necessary for the router to identify
and tailor the connection to the remote network’s router. Once this is done, a connection between the two routers
can be made and computers on each network can communicate with each other.
Dial-In Network Connections
A dial-in network connection is very similar to a dial-in user connection. When the remote router dials into the DI1162/DI-1162M, the call comes into the WAN port and after answering the phone, the DI-1162:
1. Identifies the Username and Password using the authentication protocol defined in the Interface
Configuration!WAN submenu.
2. Checks the Username and Password against those defined in the Dial-In User Profiles and Remote Network
Profiles.
3. Assuming a matching Remote Network Profile is found, the router may configure the IP address of the remote
station (as defined in the Remote Network Profile).
4. Configures the specified WAN Interface (a virtual circuit) using the configuration parameters defined in the
Interface Configuration menu and the Remote Network Profile to handle the connection.
5. Establishes the connection.
Dial-Out Network Connections
Dial-out network connections are much different than dial-in connections.
When a packet on the LAN reaches the router, the DI-1162/DI-1162M will:
1.
Check it’s routing table to try to identify where this packet should go. It looks for two variables in the routing
table, Gateway address and Interface. There are four possible results:
I. In the case where the destination resides on the LAN, the router will send out an ARP request to obtain
the MAC address of the destination computer and deliver the packet. Note that defining Static ARPs can
speed up delivery since the router won’t need to send out an ARP request.
II. In the case where the router finds a match in the routing table, it uses the Gateway address and Interface
numbers to identify the correct Remote Network Profile to use to dial out. From the Remote Network
Profile, the router gets the telephone number and other information and dials out, establishes a connection
and delivers the packet
III. In the case where no match is found in the routing table, the router will search for IP Static Routes. If a
match is found in the static routing table, the router will use the information there to find the correct
Remote Network Profile to use to dial out. If you have a connection to the Internet, it is very important
that you define the default next hop router in the IP Static Routes submenu of the console program as
your ISP (see the IP Static Routes section of this manual for more detailed configuration information).
This is because if a user on your LAN makes a request to download a web page for the first time, for
instance, since it is the first time, the DI-1162/DI-1162M will not have any record of the web page’s IP
address. If no default next hop router is defined, the request will be dropped and the user will get a
‘Destination Unreachable’ error message. However, if a default next hop router is defined in the IP Static
Routes, the DI-1162/DI-1162M will pass this request on to the ISP (the request will go through) and the
user will receive the web page.
IV. In the case where there is no match for the destination IP address in the routing table or the static routing
table, and no default next hop router is defined, the packet will be dropped and no action will be taken.
The Remote Access Configuration submenu is shown below. All items in the submenu are described as follows.
45
DI-1162/DI-1162M Remote Access Router
Dial Configuration
You can configure the two WAN interfaces on your DI-1162/DI-1162M to dial-out only when a packet is
forwarded to that interface, and hang up after all data has been transferred and the link is idle. This can be
used to lower the cost of an unpopular link or used as a backup link to your ISP. This feature is commonly
called “Dial on Demand”. WAN interfaces can also be configured here to receive calls from dial in users and
other networks, called “Remote Access”. Please note however, that in all cases, after configuring the WAN
interfaces in the Dial Configuration submenu, they must be further configured in the Dial-In User Profile
submenu or Remote Network Profile submenu.
46
DI-1162/DI-1162M Remote Access Router
Dial In IP Pool
The dial in IP pool allows you to define a range of IP addresses that will be reserved for and assigned to dialin users.
The items are described as follows:
♦ IP Address – This is the first IP Address that will be assigned to a dial-in user.
♦ Range – This is the number of IP Addresses that can be assigned. In the window shown above, dial-in users
will be assigned the IP Addresses 170.100.200.1 or 170.100.200.2 (only two are necessary since the router
used in the examples has only two WAN ports).
Dial Backup Configuration
The dial backup configuration function allows you to configure information about a backup interface. An
example of a backup interface on the Remote Network Profile menu would be making WAN 2 a backup
interface for WAN 1. Enter configuration information below to complete the dial backup configuration.
47
DI-1162/DI-1162M Remote Access Router
The items are described as follows:
♦ Backup State – Choose among Answer, Dial on Demand, Always Connect, or Disable.
◊ Answer Select this to accept phone calls.
◊ Dial on Demand This initiates phone calls to make a connection.
◊ Always Connect When this is selected, the primary line will never have a chance to be activated again.
◊ Disable Select this if you don’t want the backup function to be used.
♦ Backup Delay – This value (in seconds) is used when the primary interface fails. Once the Backup Delay
value is reached, the backup interface will be activated for use.
♦ Restore Delay – This value is used if and when the master interface is operational again. Once the Restore
Delay value is reached, the backup interface will be disconnected
WAN 1
This submenu contains a number of settings (shown below) which allow you to configure the router to dial
out.
48
DI-1162/DI-1162M Remote Access Router
The parameters are described below:
♦ Dial Retry Time – This is the time (in seconds) the router will wait before the next dial attempt.
♦ Dial Retry Count – This is the specified maximum number of dial attempts the router will make when trying
to establish a connection on this interface.
♦ Call Back Delay – This is the time (in seconds) the router will wait before calling the number designated for a
specified dial-in user.
Dial-In User Profile
The Dial-In User Profile is used to configure the DI-1162/DI-1162M for single users (for example a person
working at home) to dial in to the router and gain access to the network. At least one User Profile must be
configured for each user who will dial in (in conjunction with Dial Configuration settings). Please note that WAN
connections to computers on other networks must be defined in the Remote Network Profile submenu.
Up to eight users can be set up to dial in to the router. However, more dial-in users can be accommodated by using
a RADIUS server as described in the RADIUS Configuration section of this manual.
The Dial-In User Profile submenu appears below:
49
DI-1162/DI-1162M Remote Access Router
Select an entry from above and hit <Enter>. This screen will be blank if a dial-in user profile has not been
configured yet.
The parameters in the above window are described as follows:
♦ Name – The maximum length is 64 characters. This username is for password challenges (authentication). The
user dialing in must supply this username in order to be allowed access to the router.
♦ Password – This is the password associated with the above Name field.
50
DI-1162/DI-1162M Remote Access Router
♦ Rem CLID – Remote Caller ID. This is the telephone number of the Remote User and is used for security.
When a phone number is entered in this field, the router will make sure that the incoming call is coming from
the same phone number as the one defined here. In other words, the remote user can only be calling from the
telephone number defined here, otherwise the call will not be accepted. This function is disabled if the field is
left blank.
♦ Default IP – This is the IP address that will be assigned to the dial-in user when the IP Address Supply setting
below is set to Default. Assigning an IP address to the remote computer ensures that the IP address does not
clash with other IP addresses on your network.
♦ IP Address Supply – This field defines how the remote user will obtain an IP address. The choices include:
◊ Default – Uses the Default IP address defined above.
◊ Dynamic - Taken from the Dial-In IP pool.
◊ None - The remote user supplies their own IP Address.
♦ Call Back – This field determines if the router will allow call back to the Remote Dial-In User upon dial-in. If
this option is enabled, the router will be able to call back to the Remote Dial-In User if they request it. In such
a case, the router will disconnect the initial call from this user and dial back to the specified call back number.
The default is no call back.
♦ Phone Number Supplied by – Toggle between Router and Caller.
♦ Phone Number – If Caller is selected above, then this phone number is usually provided by the person who
initially set up the router. If Router is selected, you must enter the phone number that will be called back
yourself.
♦ Idle Time – This is the elapsed time (in seconds), of inactivity, that will trigger the router to disconnect this
interface.
♦ State – Enables/disables this User Profile.
Remote Network Profile
The Remote Network Profile is used to configure the router for WAN connections to other networks. In
practice, the DI-1162/DI-1162M will either dial-out to or receive incoming calls from another router, the
‘gateway’ to the other network.
51
DI-1162/DI-1162M Remote Access Router
Select an entry from above and hit <Enter>. This screen will be blank if a remote network profile has not been
configured yet.
The parameters in the above window are described as follows:
♦ Remote Name – Name for the remote network that the DI-1162/DI-1162M is being set up to connect with.
♦ Direction – Dial-[In], dial-[Out], or [Both]. This field defines whether the router on the other network will
dial-[In] to the DI-1162/DI-1162M to establish a connection, the router will dial-[Out] to the other network, or
a connection can be established [Both] ways.
When this is set to In, the DI-1162/DI-1162M will only establish a connection with the other network by
receiving calls on the WAN port specified in the Interface field below. Also, the incoming calls will be subject
to the Name, Password, and Rem CLID fields in the Incoming section below.
When this is set to Out, the router will only make calls on the WAN interface specified in the Interface field
below. Also, the outgoing calls will be subject to the Name, Password and Phone Number fields in the
Outgoing section below.
When set to Both, the dial in and dial out conditions described above will both be observed.
♦ Interface – WAN1 or WAN2. This field is used to assign a remote network to a logical (virtual) interface called
a virtual circuit. More than one remote network can be configured to use the same interface, but they cannot be
connected at the same time. Thus, if you wish to have two WAN connections operate simultaneously, make
sure they are configured on different interfaces. On the other hand, if you have two dial-out remote network
profiles but wish to keep one line always open for dial-in users, make sure the two dial-out profiles use the
same interface. In this case, the two profiles will share the same interface; the second one using it after the first
one’s idle time has expired and it has relinquished it.
♦ Backup Intf – Enter a backup interface in this field is desired.
♦ Phone - This is the telephone number that will be dialed to make the outgoing connection.
♦ Idle Time – This is the elapsed time (in seconds), of inactivity, that will trigger the router to disconnect this
interface.
♦ Script File ID – This is the ID in the Script File Configuration menu.
52
DI-1162/DI-1162M Remote Access Router
♦ Set Peer as default Gateway – When enabled, this feature sets the IP address of the remote device as the
default gateway (default next hop router) for all packets not found in the routing table. If the Peer IP is set as
the default gateway here, you still need to define a static default route in the Network Configuration!IP
Static Route submenu, but you don’t need to designate a gateway IP address for the static route (the routers
will automatically negotiate and adjust the gateway IP setting accordingly). And also make sure that the
Remote IP Address in the Remote Networks Profile is set to 0.0.0.0.
Incoming:
♦ Name – The maximum length is 64 characters. This username is for password challenges (authentication). The
user dialing in must supply this username in order to be allowed access to the router.
♦ Password – This is the password associated with the above Name field.
♦ Rem CLID – Remote Caller ID. This is the telephone number of the Remote User and is used for security.
When a phone number is entered in this field, the router will make sure that the incoming call is coming from
the same phone number as the one defined here. In other words, the remote user can only be calling from the
telephone number defined here, otherwise the call will not be accepted. This function is disabled if the field is
left blank.
♦ Call Back – This field determines whether the router calls back after receiving a call from this Remote
Network Profile. If this option is enabled, the router will disconnect the initial call and call back to the phone
number that you provide. Note that this field will be valid only if the Direction setting above is Both.
Outgoing:
♦ Name – The maximum length is 64 characters. Spaces and punctuation are not usually accepted. This
username is for password challenges (authentication) which are automatically handled by the router when
dialing out. The DI-1162/DI-1162 will use PAP and CHAP (whichever works) to make the connection.
♦ Password – This is the password associated with the above Name field.
♦ Remote IP Address – This is the IP address that will be assigned to the dial-in network when the IP Address
Supply setting below is set to Default. Assigning an IP address to the router dialing in ensures that the IP
address does not clash with other IP addresses on your network. For dial out connections utilizing dial on
demand, the IP address of the remote router needs to be entered here so the router knows which remote
network to establish a connection with to deliver the packet.
♦ IP Address Supply – This field defines how the router will assign an IP address to a device dialing in. The
choices include:
◊ Default – Uses the Remote IP address defined above.
◊ Dynamic – Taken from the Dial In IP pool.
◊ None – The remote user supplies their own IP Address.
♦ Multi-Link PPP – Enables/disables multi-link PPP on this port. Individual ports can be set to join the MLPPP
bundle by enabling Multi-Link on each port. When enabled, the port will join the MLPPP bundle. Please note
that this router contains only one MLPPP bundle. All ports taking part in MLPPP, even the first or primary port
which initially establishes the connection, must have Multi-Link enabled. The port that first established the
connection is the Primary Port and will not disconnect due to a BOD Low Threshold event, but is subject to
Dial on Demand (DOD) settings.
♦ Compression – Enables or disables Stac compression. This is an industry standard using a 4:1 compression
scheme. When enabled, the router will try to use Stac compression on the designated port whenever possible. If
the destination device is not capable of using Stac compression, the two devices will still communicate, albeit
without using Stac compression. When disabled, Stac compression will never be used on this port
♦ State – Enables or disables this Remote Network Profile.
53
DI-1162/DI-1162M Remote Access Router
Script File Configuration
Script files are used on dial-out connections where the server you are connecting to uses a script for the logon
procedure (common with many ISP’s). If you would like the router to automatically logon to a remote server, you
must define a script file.
Script files are executed immediately upon successfully establishing a connection. The DI-1162/DI-1162M can
hold up to 8 different script files.
Press <Enter> in a script name field to define a script file.
Script File Example
The example script file shown below assumes a connection to an Internet Service Provider.
54
DI-1162/DI-1162M Remote Access Router
Commands
Script files can perform six Commands. You can choose the appropriate command by positioning the cursor in the
Command field and pressing <space bar> to toggle to the desired command. The script commands are defined as
follows:
♦ Wait – This command waits for text defined in the Parameter field to be transmitted by the ISP. In the above
example, the router will wait for the ISP to prompt for ‘Username:’. Please note that the parameters are
case-sensitive and must be an exact match.
♦ Transmit – Transmits the exact characters written in the Parameter field. There are also three keywords that
can be transmitted:
◊
^I –
Username, as defined in the Remote Network Profile submenu.
◊
^P –
Password, as defined in the Remote Network Profile submenu.
◊
^M –
<Enter> or <Return>.
♦ Delay – Will delay for the number of seconds defined in the Parameter field.
♦ Get My IP – Will get the IP address from the ISP if the ISP sends it. This command is only valid for SLIP
connections.
♦ Get Srv IP – Will get the Servers IP address if it is sent. This command is only valid for SLIP connections.

DI-1162/DI-1162M Remote Access Router
DHCP Configuration
The DI-1162/DI-1162M Router implements the Dynamic Host Configuration Protocol (DHCP), which allows the
entire IP network to be centrally managed by the router. It does this by assigning IP addresses and configuration
parameters to hosts as they are powered on and come onto the network. This can be a great help for network
administration since many administrative tasks such as keeping track of each computer’s IP address are handled by
the router. The DI-1162/DI-1162M can implement DHCP in one of the two ways shown below:
DHCP Server Configuration
When acting as a DHCP server, the DI-1162/DI-1162M will manage many of the IP network parameters. The
DI-1162/DI-1162M will never assign a broadcast or network IP addresses to hosts, even if such an address is
included in the specified range.
56
DI-1162/DI-1162M Remote Access Router
Dynamic IP Pool
The Dynamic IP Pool screen shown below contains the parameters that the router can set on the hosts. Please note
that the Dynamic IP Pool cannot be enabled when the DHCP Agent feature is enabled.
The parameters are described below:
♦ IP Address – This is the base (starting) address for the IP pool of unassigned IP addresses.
57
DI-1162/DI-1162M Remote Access Router
♦ Range – This is the range of contiguous, IP addresses, above the base IP Address above. In the above
example, the IP Addresses assigned would be 202.93.47.1, 202.93.47.2, … 202.93.47.100.
♦ Netmask – This mask informs the client, how the destination IP address is to be divided into network, subnet,
and host parts. The netmask has ones in the bit positions in the 32-bit address which are to be used for the
network and subnet parts, and zeros for the host part.
♦ Gateway – This specifies the Gateway IP Address that will be assigned to and used by the DHCP clients.
♦ Lease Time – This specifies the number of hours a client can lease an IP address, from the dynamically
allocated IP pool. A value of 65535 means the lease is permanent.
♦ DNS IP – This specifies the Domain Name System server, used by the DHCP clients using leased IP
addresses, to translate hostnames into IP addresses or vice-versa.
♦ WINS IP – This specifies the IP address of the Windows Internet Naming Service server. This server has
software that resolves NetBIOS names to IP addresses.
♦ Domain Name – This is the common suffix, shared by networked hosts, used to represent a common network
domain.
♦ State – This toggles Disable and Enable for DHCP function.
Static IP Pool
The Static IP Pool configuration functions in much the same way as the Dynamic IP Pool configuration. The only
difference is that a particular IP address can be assigned to a particular host. The host is identified by the MAC
Address of its NIC, which must be entered on this screen.
Select an entry from above and hit <Enter>. This screen will be blank if a static IP pool has not been configured
yet.
58
DI-1162/DI-1162M Remote Access Router
The parameters are described below:
♦ IP Address – This is the static IP address to be assigned.
♦ MAC Address – This specifies the physical address of the particular host that will receive the above IP
address.
All other parameters (Netmask, Gateway, DNS IP, WINS IP, State, and Domain Name) are identical to those in
the Dynamic IP Pool configuration, in the previous section.
DHCP Relay Agent
The DHCP Relay Agent feature allows the DI-1162 to act as a go-between for a remote DHCP server assigning IP
addresses to local clients. This can be useful if you wish to have all IP addresses in your company, including those
in branch offices, assigned from a DHCP server centrally located at your headquarters, for example.
59
DI-1162/DI-1162M Remote Access Router
Items are described as follows:
♦ DHCP Server IP Address – This is the IP address of the remote DHCP server. When a local computer
powers up and sends a DHCP request for an IP address, the DI-1162/DI-1162M will forward the request to the
address specified here.
♦ Time Threshold – This specifies the maximum amount of time (in seconds) since the host began requesting an
IP address. If the value define here is exceeded, the relay agent will not pass along the request from the host.
♦ State – Enables or disables the DHCP Relay Agent function.
Filter Configuration
Your DI-1162/DI-1162M uses filters (configurable at two layers) to screen packet data, and apply a routing
decision. There are two methods of configuring a filter: you can configure a filter at the network layer (IP filter) to
restrict access between networks and reduce unnecessary internetwork traffic; and you can configure a filter at the
data-link layer (a general filter) to provide a protocol independent filter.
Good knowledge of network protocols is required to configure a specific filter appropriately. It is important for
the router to operate correctly, therefore, necessary packets must be allowed to pass through the filters. In other
words, do not attempt to configure filters on a utilized router unless you understand what you are doing.
The following section describes how to configure the router filter parameters.
Configuring a Filter Set
Under the Advanced Functions menu, select and enter the Filter Configuration screen:
60
DI-1162/DI-1162M Remote Access Router
The three submenus are described as follows:
1.
Filter State of Interface – This is used to choose the default, routing decisions for packets, not meeting the
criteria for specific filters.
2.
Layer 2 Filter – This is a data-link layer (protocol independent) filter. Foreknowledge of the specific
protocol, used on the interface (LAN or WANs), is needed to make effective use of this filter.
3.
IP Filter – This is an IP protocol specific filter, allowing you to, among other things, prohibit specific packets
from entering the LAN. Alternatively, you can set up filters that allow certain types of IP packets to enter the
LAN.
4.
IPX Filter – This contains information necessary to set up an IPX filter (DI-1162M only).
Filter State of Interface
The Filter State of Interface submenu lets you toggle default, routing decisions, if the packets are not subjected
to a filter, routing decision. In other words, a packet, having not met the criteria for a specific filter that was
applied to a specific interface, will be subjected to this default, routing decision.
61
DI-1162/DI-1162M Remote Access Router
Please note that the IPX Filter column will only appear on DI-1162M models. Each decision on handling packets
is described below:
1. Disable – This does not apply a default, routing decision.
2. Forward – This allows the routing of a packet, even though it has not met the criteria of the corresponding
filter.
3. Drop – This drops (doesn’t allow routing for) a packet that has not met the criteria for the corresponding
filter.
Layer 2 Filter
The Layer 2 Filter submenu contains a protocol independent (data-link layer) filter. Foreknowledge of the
specific protocol used on the interface (LAN or WANs) is needed to make effective use of this filter.
62
DI-1162/DI-1162M Remote Access Router
Select an entry from above and hit <Enter>. This screen will be blank if a layer 2 filter has not been configured
yet.
The parameters of a filter are described below:
♦ Name – This is a 12 character (maximum), alphanumeric, user-defined name, used to identify the filter.
♦ Direction – This defines the direction of the frame relative to the Interface parameter. In means that packets
will be checked when they are received from this interface. Out means that packets are checked as they are sent
out from this interface.
63
DI-1162/DI-1162M Remote Access Router
♦ State – This is used to choose the routing decision applied to the frame. The three decisions are described:
1.
2.
3.
Forward – This allows the routing of the frame, if it has met the criteria of the corresponding filter.
Drop – This drops (doesn’t allow routing for) a specific frame that has met the criteria of the
corresponding filter.
Disable – This does not apply the protocol independent filter.
♦ Interface – This applies the filter to a specific interface, either LAN or one of the WANs.
♦ Offset – This defines the reference byte for the Length parameter (described below). The Offset is the number
of bytes (octets) from the beginning of the first byte of the frame header, immediately after the preamble. The
range of the Offset parameter is from 0 to 255 octets. The first byte in a packet has an offset 0.
♦ Length – This is the number of bytes (octets) from the offset value (the Offset reference byte).
♦ Value – This is a 16 digit, hexadecimal field, defining the actual bit values used to compare with the frame
data, at the specified (Offset + Length) position.
♦ Mask – This is a 16 digit, hexadecimal bit mask, used as an operand in the bit-wise AND operation that will be
applied to the Value parameter.
IP Filter
The IP Filter is specifically an IP protocols filter, allowing you to, among other things, firewall your LAN,
prohibiting specific packets from entering your LAN. It is necessary to have good knowledge of IP protocol before
effectively configuring this filter.
Select an entry from above and hit <Enter>. This screen will be blank if an IP filter has not been configured yet.
64
DI-1162/DI-1162M Remote Access Router
The IP Filter parameters are described below:
♦ Name – This is a 12 character (maximum), alphanumeric, user-defined name, used to identify the IP filter.
♦ Direction – This defines the direction of the packet relative to the Interface parameter below.
♦ State – This is used to define the routing decision applied to the packet. The three routing decisions are
described:
1.
2.
3.
Forward – This allows the routing of the packet, if it has met the criteria of the corresponding IP filter.
Drop – This drops (doesn’t allow routing for) a specific packet that has met the criteria of the
corresponding IP filter.
Disable – This does not apply the IP filter.
♦ Interface – This applies the IP filter to a specific interface, LAN or one of the WANs.
♦ Protocol Type – This is a protocol identifier, as assigned by the Internet Assigned Numbers Authority
(IANA). The values of this identifier are described in RFC-1700. This router supports the following:
1.
protocol type = 1, this is Internet Control Message (ICMP), defined in RFC 792.
2.
protocol type = 6, this is Transmission Control (TCP), defined in RFC 793.
3.
protocol type = 17, this is User Datagram (UDP), defined in RFC 798.
4.
protocol type = 0, this includes ICMP (1), TCP (6), and UDP (17).
♦ Src IP – This is the source address in the IP header of this packet.
♦ Src Netmask – This mask is bit-wise AND’d with the source IP address, and compared to the IP address of the
incoming interface, for which the packet arrived.
♦ Src Port – This is the source port in the TCP or UDP header of the packet.
♦ Src Port Operation – Select a source port operation: None, EQ, GT, or LT.
♦ Dst IP – This is the destination address in the IP header of the packet.
65
DI-1162/DI-1162M Remote Access Router
♦ Dst Netmask – This mask is bit-wise AND’d with the destination IP address, and compared to the IP address
of the outgoing interfaces.
♦ Dst Port – This is the destination port, in the TCP or UDP header, of the packet.
♦ Dst Port Operation – This comparison operation is applied to the destination port (the Dst Port parameter)
value, of the TCP or UDP header.
♦ ICMP Type – This is the type field, in the ICMP header, used to identify a particular ICMP message.
♦ ICMP Code – This is the code field, in the ICMP header, used to further specify the ICMP type.
♦ TCP Flag – This is a decimal number, representing the six flag bits in the TCP header.
IPX Filter Configuration
Highlight the desired entry on the IPX Filter Configuration screen and then press <Enter> to access the
following screen
IPX Filter
The IPX Filter is specifically an IPX protocols filter, allowing you to, among other things, firewall your network,
prohibiting specific packets from entering or going out from your network. It is necessary to have knowledge of
IPX protocol before effectively configuring this filter.
66
DI-1162/DI-1162M Remote Access Router
Select an entry from above and hit <Enter>. This screen will be blank if an IPX filter has not been configured yet.
The IPX Filter parameters are described below:
♦ Name – This is a 12 character (maximum), alphanumeric, user-defined name, used to identify the IPX filter.
♦ State – This is used to define the routing decision applied to the packet. The three routing decisions are
described:
1.
Forward – This allows the routing of the packet, if it has met the criteria of the corresponding IPX filter.
67
DI-1162/DI-1162M Remote Access Router

♦ Destination Node – This field contains the address of the node on which the router resides. This is usually the
MAC address of this device.
♦ Destination Socket – This field contains the socket number on which the router will receive service requests.
♦ Source Network Number – This is the IPX network number of the network where the packet originated.
♦ Source Node – This field contains the MAC address of the originating machine.
♦ Source Socket – This field contains a specific socket number which IPX packets can be discarded.
IPX SAP Type Filter
The SAP type filter parameters are described below:
♦ Type – This is used to remove selected incoming service access information before it is entered into the service
information table for the router.
♦ State – Toggle to Enable or Disable this filter.
Multiple Home Configuration
Besides the IP address assigned to the LAN interface in the Network Configuration menu, each LAN may have
up to 3 additional IP interfaces. These additional IP interfaces are referred to as MIP’s and MIP1 to MIP3 are
68
DI-1162/DI-1162M Remote Access Router
reserved for LAN1 and MIP4 to MIP6 are reserved for LAN2 (if present). This type of configuration is known as a
multiple home configuration.
Multiple Home can be demonstrated by this example:
A company has 625 users (computers) all connected to one physical network using Ethernet. However, the
company only has one Class C IP network address, 202.100.160.0. This network address will only support 254
users. To solve the shortage of IP address problem and to plan for future growth, the company applies for and
receives two more Class C IP network addresses, 203.101.161.0 and 204.102.162.0. This gives the company a
total of 254 x 3 = 762 IP Addresses, which it assigns to the computer users, with a few left over for future needs.
Due to the nature of IP networks, however, the users in one IP network domain (202.100.160.0, for example)
cannot communicate with users on a different IP domain (203.101.161.0). Multiple home solves this problem.
When you register the additional IP network addresses in the Multiple Home Configuration menu on the router,
the router will route data between the three IP networks using the single LAN.
In this router, multiple home configurations only apply to the LAN interface.
69
DI-1162/DI-1162M Remote Access Router
The parameters are described below:
♦ IP Address – This is a network IP address, access point, to a separate, physical network, on the LAN.
♦ Routing Protocol – This is the same as in the Network Configuration section. Keep in mind that these
exchanges are made with adjacent routers on the LAN, if present.
♦ IP Multicasting – This enables/disables IP multicasting on the IP network you are defining.
All other parameters (Netmask, Routing Mode, Multicast Protocol and IGMP Version) are identical to those in the
Network Configuration section.
Static ARP
This special function is intended to speed up the process of finding a host's Ethernet (MAC) address from its
network address, and provides a special condition – any other host acting as an impostor by using the same IP
address as the legitimate host, will be ignored by this router.
Basically, when a packet comes into the router from a WAN port and is destined for a host on the LAN, the router
will use information defined here to immediately send the packet to the host rather than send out an ARP request to
find the host’s MAC address.
70
DI-1162/DI-1162M Remote Access Router
Select an entry from above and hit <Enter>. This screen will be blank if a static ARP entry has not been configured
yet.
The parameters are described as follows:
♦ IP Address – This is the IP address that causes the router to reply with the MAC Address upon receiving an
ARP request.
♦ MAC Address – This is the physical address, of the host, that is the authorized owner of the IP address.
71
DI-1162/DI-1162M Remote Access Router
♦ State – This toggles Enable and Disable.
NAT Configuration
Network Address Translation (NAT) is a routing protocol that allows your network to become a private network
that is isolated from, yet connected to the Internet. It does this by changing the IP address of packets from a global
IP address usable on the Internet to a local IP address usable on your private network (but not on the Internet) and
vice-versa.
NAT has two major benefits. First, NAT allows many users to access the Internet using a small number or even a
single global IP address. This can greatly reduce the costs associated with Internet access and also helps alleviate
the current shortage of Internet IP addresses. Secondly, the NAT process creates a firewall which hides your local
network from Internet users, providing a degree of security to your Internet connection.
To be successfully implemented, NAT should be used only when the majority of network traffic remains on the
local network. In cases where a large percentage of network traffic is destined for the Internet, NAT can adversely
affect the speed and performance of your Internet connection. Also, your network servers such as ftp servers, web
servers or mail servers will probably need to be assigned static NAT IP addresses so their IP addresses remain
consistent. This issue will be further discussed later.
Network Address Port Translation (NAPT) is a subset of NAT where many local IP addresses and their TCP/UDP
port numbers are translated to a single global IP address and it’s TCP/UDP port number. In this document, the
term NAT will refer to both NAT and NAPT unless otherwise stated.
NAT can work in conjunction with DHCP. Thus, if both are enabled and properly configured, the DHCP server in
the DI-1162/DI-1162M will assign local IP addresses to computers on your network.
How NAT Works
In the most common NAT configuration, your network uses local IP addresses that are not valid on the Internet.
Internet (global) IP addresses are unique, with no two devices have the same IP address. The local IP addresses
can be freely assigned to computers on your network by your network administrator (within guidelines defined
later in this chapter and in “Appendix C, IP Concepts”). This can be done manually or by using DHCP. The WAN
port on the router is assigned a globally unique IP Address that IS valid on the Internet, since it will be sending and
receiving data directly to the Internet and is therefore part of it. Please study the example diagram below carefully.
72
DI-1162/DI-1162M Remote Access Router
Please note that in the above diagram, the Gateway IP address settings for the local PC’s needs to be set to
192.168.100.1, the LAN IP address of the router.
NAT manipulates the IP addresses in packet headers on a one-to-one basis. An outgoing data packet (a packet
originating from a computer on the local LAN and destined for a computer outside the private network) will have
its IP address translated as shown below.
In the Outgoing Data Packet above, the Source IP address is the IP address that is translated by NAT. The
Destination IP Address is the IP address of a computer outside the private network, on the Internet for example.
And the Data portion of the packet is the information payload borne by the packet, for instance a request to view a
web page.
The router logs the changes made to the IP header in its NAT table. The NAT table enables the router to send
replies back to the local computer as shown below.
In the Inbound Data Packet above, the Destination IP Address is the IP address that is translated by NAT. The
Source IP Address is the IP address of a computer outside the private network. And the Data portion of the packet
is the information payload borne by the packet, in this case, web page contents.
The actual information in the NAT table depends whether the router is implementing NAT or NAPT.
NAT
This section discusses the NAT protocol as opposed to NAPT which is discussed in the next section.
NAT is the initial protocol set forth by RFC 1631 and provides a means in which private networks can
communicate with the Internet by using a small number of IP addresses. In our discussion, we will use the example
IP addresses listed in the table below and the network diagram shown at the beginning of this section.
Global IP Addresses
(for use with NAT)
Local IP Addresses
(assigned to computers
on the local network)
200.100.50.1
200.100.50.2
200.100.50.3
200.100.50.4
200.100.50.5
192.168.100.1
192.168.100.2
192.168.100.3
192.168.100.4
192.168.100.5
192.168.100.6
192.168.100.7
192.168.100.8
192.168.100.9
192.168.100.10
Please note that in the above table there are 9 users on the local network using 5 global IP addresses to access the
Internet.
73
DI-1162/DI-1162M Remote Access Router
When a packet on the local network arrives at the router and needs to be sent to the Internet, NAT will change the
source IP address (for example 192.169.100.2) to a global address (200.100.50.1, for example). If this packet
generates a reply (as for example, a request to view a web page will), NAT will change the destination IP address
on the reply packet back to the local IP address for delivery to the machine on the local (stub) network.
The difference between static and dynamic NAT is that once the five global addresses are assigned when using
static NAT, they will never change. The only way to change them is by using the console program to manually
reassign them. When using dynamic NAT, the router will map a local IP address to a global IP address whenever a
request is made. Since there are only 5 global IP addresses in the example above, there can only be 5 mappings at
any one time. In other words, much like static NAT, only 5 local machines can access the Internet at any one time.
However, contrary to static NAT, the router will discard the mapping between the global and local IP addresses
after a certain length of time (which is quite long so rarely happens), or after the session is finished (an example of
a session is when requesting a web page, the entire page has completed downloading). The most common
implementation of NAT is to define a range of dynamic addresses to be used by hosts, but assign static addresses
to your servers if you wish for them to be accessible from outside your network.
Setting Local IP Addresses
When implementing NAT and thus creating a private network that is isolated from the Internet, you can assign any
IP addresses to host computers without problems. However, the Internet Assigned Numbers Authority (IANA) has
reserved the following three blocks of IP Addresses specifically for private networks:
Class
Beginning Address
Ending Address
A
B
C
10.0.0.0
172.16.0.0
192.168.0.0
10.255.255.255
172.31.255.255
192.168.255.255
It is recommended that you choose local IP addresses for use with NAT from the private network IP addresses in
the above list. For more information on address assignment, refer to RFC 1597, Address Allocation for Private
Internets and RFC 1466, Guidelines for Management of IP Address Space.
74
DI-1162/DI-1162M Remote Access Router
Configure NAT/NAPT
The first screen shows the complete NAT table that is defined by the network manager:
For any NAT entry, you must configure two different screens. The first one is accessible by positioning the cursor
over the name field and hitting <Enter> (in the window shown above, this corresponds to the field ‘02507’). After
configuring the NAT options in the Name field, you must save the changes, exit, and position the cursor over the
NAT IP Pool to configure variables there.
Name Field Configuration Screen
The configuration screen for the name field appears as follows:
75
DI-1162/DI-1162M Remote Access Router
The parameters are described as follows:
♦ Name – This is a 12 character, alphanumeric, user-defined name, used to identify the network address
translation.
♦ Global Interface – This is the interface corresponding to the Global IP and Range parameters, in the NAT
table, to form unique IP address[es], known to the outside (regional or Internet) routers, on this interface.
♦ Local Interface – This is the interface corresponding to the Local IP and Range parameters, in the NAT table,
to form local IP address[es], known only to this interface and the network within.
♦ Translation Mode – This toggles choices of four types of NATs:
◊ Static NAT – Maps one global IP address to one local IP address. After all global IP addresses are assigned,
they will remain static. This option may be necessary for email, web, ftp servers, etc. where static IP
addresses are essential for operation.
◊ Dynamic NAT – Maps one global IP address to one local IP address. Global IP addresses will be
dynamically reassigned to different local IP addresses if not currently being used. This allows a larger
number of users to use a small number of IP addresses.
◊ Static NAPT – One to one mapping of UDP/TCP port numbers to let packets with specific UDP/TCP port
numbers enter the local IP domain. The NAPT map table will not age. This option may be necessary for
email, web, ftp servers, etc. where static port numbers are essential for operation. Setting the global port
number to 0 opens port numbers 1024 to 65535 for the designated local IP address, creating a visible
computer. This allows a computer to be freely accessed by other computers on the Internet, which is
necessary for some applications to function correctly when using NAPT, including Microsoft NetMeeting,
CUSeeMe, etc.
◊ Dynamic NAPT - One to one mapping of UDP/TCP port numbers. The NAPT map table will age. This
option allows many hosts to use a single, globally unique IP address, and thus will only be used on
outbound packets.
♦ State – Enables/disables this NAT configuration.
76
DI-1162/DI-1162M Remote Access Router
NAT IP Pool Configuration Screen
Now you must select, enter, and configure the NAT IP Pool from the NAT Configuration submenu, shown
below.
Dynamic NAT
This screen (below) is how the NAT IP Pool appears, if Dynamic NAT was chosen for the Translation Mode
parameter. Each entry, in this configuration, can be used to map multiple, contiguous global addresses and local
addresses to each other.
The parameters are described below:
♦ Global IP – An IP Address that is globally unique and valid on the Internet. It is the base, global address for
the global addresses that will be recognized by the interface in the Global Interface parameter.
♦ Range – This is the range of contiguous, global addresses above (and including) the base Global IP.
♦ Local IP – An IP Address that is only used in the stub domain since it is not unique. It is the base, local
address for the local addresses that will be recognized by the interface in the Local Interface parameter.
♦ Range – This is the range of contiguous local addresses above (and including) the base Local IP.
♦ State – This toggles Enable or Disable for this NAT entry.
Dynamic NAPT
This screen (below) is how the NAT IP Pool appears, if Dynamic NAPT was chosen for the Translation Mode
parameter. Each entry, in this configuration, can be used to map a single global address and multiple, contiguous
local addresses to each other.
77
DI-1162/DI-1162M Remote Access Router
All of the parameters are the same as in Dynamic NAT, except the Global IP is a solitary, global address.
♦ Global IP – this is a single, globally unique IP Address of the global interface (the interface to which it is
assigned, in this case, one of the WAN interfaces) that is valid on the Internet.
Static NAT
This screen (below) is how the NAT IP Pool appears, if Static NAT was chosen for the Translation Mode
parameter. Each entry in this configuration is used to map a single global IP address a single local IP address.
78
DI-1162/DI-1162M Remote Access Router
The parameters are described as follows:
♦ Global IP – This is a single, global IP Address that is valid on the Internet, or on the same subnet of the global
interface.
♦ Local IP – This is a single, local IP Address that is not valid on the Internet.
Static NAPT
This screen (below) is how the NAT IP Pool appears, if Static NAPT was chosen for the Translation Mode
parameter. Each entry in this configuration can be used to map a global address and port to a local address and
port. Notice that the global address will be the external IP address of the global interface.
♦ Port – This is a destination port number, used by TCP and UDP, to de-multiplex the incoming IP packet.
In the above example, incoming packets with the global destination IP Address (211.11.22.2) and global
destination TCP/UDP port (21) will be translated to a packet with the local destination IP Address (1.1.1.5) and
local TCP/UDP port (21).
Port 21 is assigned to FTP servers. Please see “Appendix D” for more commonly assigned port numbers, or RFC
1700 for a more complete list.
NAPT for Special Aps
Some applications programs that are used over the Internet such as Microsoft NetMeeting, Diablo, and CU See Me
send information to a certain port number or within a specified range of port numbers. The exact port number used
is specific to the application. However, if you find that you are having trouble using an application over the
Internet and you are using NAPT, you may need to exempt certain port numbers from the NAPT port translation
process. Please refer to the user guide for the program to find out whether it transmits and receives data only
through specified IP port numbers. In order for these programs to work with NAPT, the IP port numbers required
by these applications must be entered in the Configure NAPT for Special APs screen shown below.
79
DI-1162/DI-1162M Remote Access Router
In the above window, position the cursor on any of the numbered name fields and press <Enter>. This will take
you to the NAPT configuration screen for special applications shown below.
The fields in the above window are described as follows:
♦ Protocol – UDP or TCP. This field designates the type of packets that will be acted on.

DI-1162/DI-1162M Remote Access Router
♦ Start Port – Some applications can only send data over a certain range of port numbers. Thus, all port
numbers in the specified range must be exempt from the NAPT port translation process. This field defines the
beginning range of the port numbers to be exempted from the NAPT port translation process.
♦ End Port – This field defines the last port number in the range of numbers excluded from the NAPT process
(see Start Port above).
♦ Connection Type – OutgoingControl or IncomingData. The user must initially run the special application and
send a request to the application server on the Internet. This outgoing request to join a Netmeeting session, for
example, is used to trigger the exemption process for the incoming data.
In the example for the game Diablo shown in the above screen, if a packet is sent out on the TCP port number
6112 (a request by a local user to a Diablo server on the Internet to join a group game), all incoming packets on
the UDP port 6112 (game data) will not be translated by NAPT.
Please keep in mind that the user will always initiate use of the special application. Thus, the first entry should
always have the Connection Type of Outgoing Control. Also, since the defined port number or range of port
numbers will be mapped to the user who triggered the outgoing control, all incoming data will be sent to that user.
Consequently, only one user can use the special application at a time.
Telnet/Discovery Enable
The fields in the above window are described as follows:
♦ Telnet State - This feature enables or disables the router’s ability to be configured over the LAN using telnet.
♦ Discovery Function – Enabling this feature allows the router to be auto-discovered by D-Link SNMP
management software and the included Windows-based configuration software called RouterView.
81
DI-1162/DI-1162M Remote Access Router
DNS Configuration
The DI-1162/DI-1162M router has a built in recursive DNS server. The maximum amount of memory that will be
used by the router’s Domain Name Server is 64Kb which averages out to be about 800 entries. In other words, up
to 800 domain names and their associated IP Addresses can be stored, which can significantly speed up access to
those domains. The routers DNS table will age out about every 24 hours, ensuring that the most frequently
accessed domains consistently benefit from the improved access times provided by using the routers own DNS.
The IP Addresses for domain names not stored in the router must be acquired from a DNS server on the Internet.
Thus, if you are using DNS, make sure you also specify an IP Address to a DNS server in the Forward DNS
queries to field.
The items in the above submenu are described as follows:
♦ DNS Server State – Enables or disables recursive DNS on this router.
♦ Lookup Host Table – Enables or disables DNS to reference up to eight host names defined in the Host Table
shown below.
♦ DNS Domain Name – The domain name suffix in which the router resides, to be appended to the host name
defined in the host table.
♦ Forward DNS queries to – A large server dedicated to resolving domain names on the Internet. This field
should contain the IP Address for the DNS closest to you.
♦ DNS Cache State – When this item is enabled, the router will add the domain names and IP Addresses it
retrieves from DNS queries to it’s own recursive DNS table.
♦ Host Table – Select this item to access the screen below.
82
DI-1162/DI-1162M Remote Access Router
Host Table
The host table allows the router to recognize host names on the network. Up to eight host names can be entered in
the table. Your network servers, especially your mail server should be defined here. Leftover places in the table
can be assigned to individual hosts to speed up routing.
In the example below, the host name ctsnow is combined with the domain name defined in the DNS
Configuration submenu above (in this case, dlink.com) to produce ctsnow.dlink.com. The mapping in the
example of ctsnow.dlink.com to the IP Address of 11.1.1.3 is only valid for computers which set the
DI-1162/DI-1162M router as their DNS server.
Items are described as follows:
♦ IP – The IP address for the host.
♦ Host Name – The host name used by the host.
♦ State – Enables or disables entry.
RADIUS Configuration
RADIUS is a password protocol where passwords are stored on a RADIUS server. RADIUS allows large numbers
of passwords to be stored in a centralized location. Before instituting RADIUS, please setup and install a RADIUS
server on the LAN.
83
DI-1162/DI-1162M Remote Access Router
Items in the above submenu are described as follows:
♦ RADIUS State – Enables or disables RADIUS.
♦ Type – Refers to the type of external password protocol. Currently, only RADIUS is supported.
♦ Server IP Address – This is the IP Address of your UNIX or NT-based RADIUS server.
♦ Port – The port number for the RADIUS server. The standard port number specified by RFC 1700 is 1812
(shown above).
♦ Key – This is a password used to identify the router as a valid RADIUS client.
Multi-Link PPP Configuration
Multi-link PPP (MLPPP) is a standard (RFC 1990 and RFC 1717) for inverse multiplexing, a method of
combining individually dialed channels into a single, higher speed data stream. MLPPP is an extension of PPP that
supports the ordering of data packets across multiple channels. Although MLPPP can be implemented on any
WAN device, it was the rapid emergence of ISDN BRI as a cost efficient higher bandwidth alternative to modems
which has driven the evolution and acceptance of MLPPP. Typically MLPPP is used to combine the speed of two
ISDN BRI B-Channels to get 128Kbps of virtual capacity.
Before implementing MLPPP on the DI-1162/DI-1162M, please ensure that your ISP or the device to which you
are connecting supports, and is configured for MLPPP.
MLPPP can be implemented in two ways, dynamically through the use of the Bandwidth on Demand (BOD), and
statically. BOD causes the second WAN port to place a call and add bandwidth to the WAN connection when the
BOD High Threshold is exceeded for the Add Bandwidth Delay period. Bandwidth can also be subtracted when
WAN throughput falls below the BOD Low Threshold and Subtract Bandwidth Delay parameters. Thus, BOD
economizes MLPPP by maintaining only the bandwidth needed.
84
DI-1162/DI-1162M Remote Access Router
A static implementation of MLPPP is achieved when BOD is disabled but the WAN ports have Multi-Link
enabled. In this case, when the two WAN ports have established a connection, the router will check to see if they
are connected to the same source and whether the source supports MLPPP. If both conditions are met, the router
will automatically bundle the two links together as an MLPPP connection.
Items in the screen are described as follows:
♦ Max Ports – Maximum ports allowed per multi-link bundle.
♦ Bandwidth on Demand – Enables or disables BOD. When enabled, BOD will manage the implementation of
MLPPP using the parameters defined in this window.
♦ BOD Criteria – Either TX, RX or TX or RX, where TX is Transmit and RX is Receive. The parameter defined
here is used when monitoring the BOD High Threshold and BOD Low Threshold.
♦ BOD High Threshold (%) – (0 to 100) The throughput value as a percentage of total bandwidth which will
cause the next WAN port having Multi-Link PPP enabled to dial up and add bandwidth to the connection.
This value, however, must be constantly exceeded for the time designated in the Add Bandwidth Delay field
before the next WAN port dials out.
♦ BOD Low Threshold (%) – (0 to 100) The throughput value as a percentage of total bandwidth which will
cause the highest numbered WAN port in the MLPPP bundle to hang up, thus subtracting bandwidth from the
connection. Before actually hanging up however, the throughput must be below this value for the time
designated in the Subtract Bandwidth Delay field.
♦ Add Bandwidth Delay (sec) – (0 to 999) The amount of time in seconds the router will wait and sample the
BOD Criteria before adding bandwidth once the throughput exceeds the BOD High Threshold. This prevents
costly bandwidth from being unnecessarily added due to temporary bursts in traffic.
♦ Subtract Bandwidth Delay (sec) – (0 to 999) The amount of time in seconds the router will wait and sample
the BOD Criteria before subtracting bandwidth once the throughput falls below the BOD Low Threshold. This
prevents bandwidth from being unnecessarily subtracted due to temporary lulls in traffic.
85
DI-1162/DI-1162M Remote Access Router
The example Multi-link PPP settings shown in the Multi-Link PPP Configuration window above assumes that
WAN 1 and WAN 2 each have a 64 kps connection configured to dial up to the Internet. When WAN 1 receives a
packet destined for the Internet it will dial the ISP and establish a connection. If the total throughput on WAN 1
(TX or RX) ever exceeds 80% of the 64 kps (51.2 kps), the router will sample the line for an additional 5 seconds.
If the traffic continuously exceeds 80% for the 5-second delay time, WAN 2 will dial up and add bandwidth to the
connection. Assuming sustained traffic of 70 kps, MLPPP will balance the traffic on the two WAN ports so they
are handling roughly 35 kps each. If the traffic on WAN 1 + WAN 2 falls below 20% of the 128 kps connection
(25.6 kps) for more than 10 seconds, WAN 2 will hang up and all traffic will be handled by WAN 1.
For the above configuration to work, both WAN ports need to have been properly setup to establish dial-out PPP
connections, and have Multi-Link enabled. Also note that WAN 1, being the lowest numbered WAN port in the
MLPPP bundle and thus the primary link, is not subject to the BOD Low Threshold parameter and will never hang
up due to BOD considerations.

LAN 1
Items in the screen are described as follows:
♦ Tx Packets – The total number of valid packets transmitted by the router since the last reset.
88
DI-1162/DI-1162M Remote Access Router
♦ Tx Bytes – The total number of bytes transmitted by the router.
♦ Tx Discard Packets – The number of packets dropped by the router.
♦ Tx Error Packets – The number of invalid packets transmitted by the router. This hardware counter shows the
sum of Collisions, Abort, and Underrun packets.
♦ Tx Collision Packets – The number of packets sent out of the router that collided on the line. Some collisions
are inevitable due to the shared nature of Ethernet. Excessive collisions show excessive utilization of the
network.
♦ Tx Abort Packets – When the router transmits a packet and a collision occurs, the router will wait a random
period and try to retransmit the packet. If a collision occurs 16 times in a row, the transmission will be aborted
and be logged by this counter. An aborted packet shows extremely heavy utilization of the network.
♦ Tx Underrun Packets – Runt packets. The number of packets transmitted by the router that are less than the
allowed 64 octets minimum length. Underrun packets occur due to jam signals generated by collisions,
backpressure, etc.
♦ Rx Packets – The number of valid packets received by the router.
♦ Rx Bytes – The total number of bytes contained in the valid packets received by the router.
♦ Rx Unknown Packets – The number of packets received by the router that were of an unsupported protocol.
♦ Rx Discard Packets – The number of packets dropped by the router.
♦ Rx Error Packets – The number of invalid packets received by the router. This hardware counter shows the
sum of CRC, FAE, Overrun, MPA and DFR error packets.
♦ Rx CRC Packets – The number of packets received that failed the CRC checksum test.
♦ Rx FAE Packets – Frame Alignment Error. The number of packets received that does not end on a byte
boundary and the CRC does not match.
♦ Rx Overrun Packets – The number of packets received that exceed the 1518-octet maximum length imposed
on Ethernet packets. Overrun packets are generated by some proprietary software applications.
♦ Rx MPA Packets – Missed Packet. This is a count of packets intended for the router, but at the time, the
router could not receive the packet (usually due to the temporary lack of receive buffers).
♦ Rx DFR Packets – Deferred Packets. This is a count of incidents where CRS (carrier signal lost) and COL
both occur at the same time. These two events happen simultaneously as a result of jabber (produced by faulty
networking equipment, usually NIC’s).

♦ Rx Error Packets - Number of invalid packets received by the router. This hardware counter shows the sum of
NOA, Abort, CRC, Overrun, CD Lost, Framing, and Parity error packets.
♦ Rx NOA Packets – Non-Octet Alignment. This counts the number of packets received by the router that did
not end on a byte boundary. The receipt of a misaligned packet will generate a single NOA event regardless of
the number of misaligned octets in the packet.
♦ Rx Abort Packet – The number of packets that were dropped due to user generated breaks in the transmission
that occurred while a packet is being received.
♦ Rx CRC Packets – The number of packets received that failed the CRC checksum test.
90
DI-1162/DI-1162M Remote Access Router
♦ Rx Overrun Packets – The number of packets received that exceed the 1518 octet maximum length imposed
on Ethernet packets. Overrun packets are generated by some proprietary software applications.
♦ Rx CD Lost Packets – Carrier Detect Lost. This counts the number of Carrier Detect packets that were lost by
the router.
♦ Rx Framing Err Packets – Packets with framing errors can occur on the WAN port only when using HDLC
in sync mode. This parameter counts the number of lost start/stop flags.

◊ TFTP ONLY – A File Transfer Protocol. Using this setting assumes all other items on this screen have been
filled out.
◊ BOOTP&TFTP – BootP is run first and sends your router IP Addresses for the TFTP server and the router,
and tells the router the path to the software update (image file). Then TFTP will be used to download the
image file.
♦ Boot Server IP Address – This specifies the IP address of the server to be used to download the image file.
♦ Boot File Name – This specifies a complete path and filename on the TFTP server. If you choose to use a
configuration file, this setting must show the path and filename to the configuration file. If you are not using a
configuration file, this must show the path and filename to the software update image file.
♦ Last Boot Server IP Address – This shows the last boot server used to download an image file. This is for
reference only.
♦ Last IP Address – This shows the last IP address used for the LAN interface. Again, this is for reference only.
The LAN port must have an IP address in order to access the TFTP server via the LAN network.
♦ Update Software from Configuration File – Either Yes or No. If Yes, the software update procedure will try
to access a configuration file located at the path defined in the above Boot File Name. Please ensure that the
path and file name of the image file is listed in the configuration file. If set to No, the update procedure will try
to find an image file at the Boot File Name path. Please see “Appendix E – Configuration File” for more

DI-1162/DI-1162M Remote Access Router
Using Telnet
The DI-1162/DI-1162M router can be configured and managed using telnet. Telnet accesses the same built-in
configuration program as the RS-232 Diagnostic port console connection. As such, all settings that can be adjusted
through the console can also be configured using Telnet.
Telnet Configuration
In order to use telnet, the DI-1162/DI-1162M router must first be configured using a console connected to the RS232 Diagnostic port. Depending on the placement of the management station using telnet, the initial configuration
requirements for the router are as follows:
Using Telnet via LAN
Preparing the router for management by telnet over the LAN only requires enabling the LAN port, enabling telnet,
and assigning the LAN port an IP address. To do this:
1. Connect a console to the RS-232 Diagnostic port on the front panel of the router and run a terminal emulation
program (for more information, see Connecting the Console to the Router and Setting Up the Console sections
of this manual).
2. Enable the LAN port in the Interface Configuration submenu.
3. Assign an IP address to the LAN port in the Network Configuration submenu.
4. Enable Telnet in the Advanced Functions submenu.
5. Connect the router to the LAN.
The router can now be accessed via the LAN by the included Windows-based Configuration program, Telnet and
SNMP management applications. For more detailed information regarding these procedures, please refer to the
Connecting the Router section of this manual. For more information about the submenus, please refer to the
Configuration and Management section of this manual.
Using Telnet via WAN
Preparing the router for management by telnet over WAN lines requires more initial configuring of the router via
the console.
To do this, you must configure a WAN port for dial-in users. Please refer to Step 3b - Configuring the WAN Ports
for Dial-in, Dial-out and Leased Lines section on page 10 of this manual.
System Timeout
When you are connected to your DI-1162/DI-1162M via Telnet, there is a system timeout (in the System
Information submenu), adjustable to a maximum of 90 minutes. If you are logged onto the device and leave it
inactive for this timeout period, the router will automatically disconnect you.
Using RADIUS Authentication
In addition to the dial-in user list, which can hold up to eight users, this model also supports an external
authentication server which may provide password storage and usage accounting for thousands of users.
117
DI-1162/DI-1162M Remote Access Router
Installing a RADIUS Server
To use RADIUS authentication, you will need to have a UNIX or Windows NT-based machine on your network to
act as a RADIUSd server, as well as a copy of the RADIUSd server program itself. You can obtain a copy of the
RADIUS software, along with documentation for the server, at
http://www.livingston.com/marketing/products/radius.html
or at:
ftp://ftp.livingston.com/pub/le/radius/
Configuring the DI-1162/DI-1162M for RADIUS Authentication
To configure the DI-1162/DI-1162M to use the RADIUS server set up in the previous section, go to the Main
Menu in the console program and choose Advanced Functions and then RADIUS Configuration.
Items in the above submenu are described as follows:
♦ RADIUS State – Enables or disables RADIUS.
♦ Type – Refers to the type of external password protocol. Currently, only RADIUS is supported.
♦ Server IP Address – This is the IP Address of your UNIX or NT-based RADIUS server.
♦ Port – The port number for the RADIUS server. The standard port number specified by RFC 1700 is 1812
(shown above).
♦ Key – This is a shared secret used to identify the DI-1162/DI-1162M as a valid RADIUS client.
The Key password should be stored in the client file in the RADIUS server’s /etc/raddb directory. Lines of
the form
118
DI-1162/DI-1162M Remote Access Router
# Client Name
Key
#----------------------------192.168.0.1
1234
should be added to the client file. The Client Name field in the file gives the IP address of the DI-1162/DI-1162M,
and the Key field should be the same as the Key field in menu 23.2.
After a RADIUS server has been configured, the DI-1162/DI-1162M will use it to authenticate all users instead of
checking it’s internal Dial-Up User Profile.
Adding Users to the RADIUS Database
The DI-1162/DI-1162M only uses the RADIUS database for user authentication; except for Password and User
Name. Most standard RADIUS attribute fields are ignored by the DI-1162/DI-1162M.
To add a user to the RADIUS database, edit the users file in the RADIUS server’s /etc/raddb directory, and
add a line similar to the following:
joeuser
Password = “joepassword”
Each user should have a user name/password record in the users database.

Appendix C - IP Concepts
This appendix describes some basic IP concepts, the TCP/IP addressing scheme and show how to assign IP Addresses.
When setting up the router, you must make sure all ports to be utilized on the router have valid IP addresses. Even if you will not use the WAN
ports, you should, at the very least, make sure the LAN port is assigned a valid IP address. This is required for telnet, in-band SNMP
management, and related functions such as “trap” handling and TFTP firmware download.
IP Addresses
The Internet Protocol (IP) was designed for routing data between network sites all over the world, and was later adapted to allow routing
between networks (often referred to as “subnets”) within any site. IP includes a system by which a unique number can be assigned to each of
the millions of networks and each of the computers on those networks. Such a number is called an IP address.
To make IP addresses easy to understand, the originators of IP adopted a system of representation called “dotted decimal” or “dotted quad”
notation. Below are examples of IP addresses written in this format:
201.202.203.204
189.21.241.56
125.87.0.1
Each of the four values in an IP address is the ordinary decimal (base 10) representation of a value that a computer can handle using eight
“bits” (binary digits — 1s and 0s). The dots are simply convenient visual separators.
Zeros are often used as placeholders in dotted decimal notation; 189.21.241.56 can therefore also appear as 189.021.241.056.
IP networks are divided into three classes on the basis of size. A full IP address contains a network portion and a “host” (device) portion. The
network and host portions of the address are different lengths for different classes of networks, as shown in the table below.
Networks attached to the Internet are assigned class types that determine the maximum number of possible hosts per network. The previous
figure illustrates how the net and host portions of the IP address differ among the three classes. Class A is assigned to networks that have more
than 65,535 hosts; Class B is for networks that have 256 to 65534 hosts; Class C is for networks with less than 256 hosts.

2,097,150
192.0.1(.0) to 223.255.254(.0)
254
All network addresses outside of these ranges (Class D and E) are either reserved or set aside for experimental networks or multicasting.
When an IP address's host portion contains only zero(s), the address identifies a network and not a host. No physical device may be given such
an address.
124
DI-1162/DI-1162M Remote Access Router
The network portion must start with a value from 1 to 126 or from 128 to 223. Any other value(s) in the network portion may be from 0 to
255, except that in class B the network addresses 128.0.0.0 and 191.255.0.0 are reserved, and in class C the network addresses 192.0.0.0 and
223.255.255.0 are reserved.
The value(s) in the host portion of a physical device's IP address can be in the range of 0 through 255 as long as this portion is not all-0 or
all-255. Values outside the range of 0 to 255 can never appear in an IP address (0 to 255 is the full range of integer values that can be
expressed with eight bits).
The network portion must be the same for all the IP devices on a discrete physical network (a single Ethernet LAN, for example, or a WAN
link). The host portion must be different for each IP device — or, to be more precise, each IP-capable port or interface — connected directly to
that network.
The network portion of an IP address will be referred to in this manual as a network number; the host portion will be referred to as a host
number.
To connect to the Internet or to any private IP network that uses an Internet-assigned network number, you must obtain a registered IP network
number from an Internet-authorized network information center. In many countries you must apply through a government agency, however
they can usually be obtained from your Internet Service Provider (ISP).
If your organization's networks are, and will always remain, a closed system with no connection to the Internet or to any other IP network, you
can choose your own network numbers as long as they conform to the above rules.
If your networks are isolated from the Internet, e.g. only between your two branch offices, you can assign any IP Addresses to hosts without
problems. However, the Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of IP Addresses specifically for
private (stub) networks:
Class
Beginning Address
Ending Address
A
B
C
10.0.0.0
172.16.0.0
192.168.0.0
10.255.255.255
172.31.255.255
192.168.255.255
It is recommended that you choose private network IP Addresses from the above list. For more information on address assignment, refer to
RFC 1597, Address Allocation for Private Internets and RFC 1466, Guidelines for Management of IP Address Space.
Subnet Mask
In the absence of subnetworks, standard TCP/IP addressing may be used by specifying subnet masks as shown below.
IP Class
Class A
Class B
Class C
Subnet Mask
255.0.0.0
255.255.0.0
255.255.255.0
Subnet mask settings other than those listed above add significance to the interpretation of bits in the IP address. The bits of the subnet mask
correspond directly to the bits of the IP address. Any bit an a subnet mask that is to correspond to a net ID bit in the IP address must be set to
1.

DI-1162/DI-1162M Remote Access Router
Appendix E – Configuration File
The router can be configured when performing a Software Update through a configuration file.
The configuration file can hold many settings for the router including IP Addresses for all ports, path to the boot
server, and various port settings.
The configuration file is very useful if you wish to update your software and keep all or most of your settings the
same.
The configuration file should be saved with the extension .SYS in the same directory as the runtime image file
(software update file).
An example configuration file is shown below. Please note that:
# : Comment. This line describes the actual configuration in the next line. You can also use this feature to
mask items you don’t need to be configured (rather than deleting them).
Format: Keyword <Space> Parameter. For example the very last line:
ip-stat disable
ip-stat is the keyword as explained in the # (comment) line above as meaning IP routing statistics.
disable is the parameter you set.
