Introduction to the Router
This chapter describes the Router and it features and includes an introduction to
ADSL technology. Diagrams are provided detailing the hardware and LED
indicators. A list of package contents is presented at the end of the chapter.
Router Description and Operation
The DSL-500 ADSL Router is designed to provide a simple, cost-effective and
secure ADSL Internet connection for your small- to medium-sized private
network. The DSL-500 combines the benefits of high-speed ADSL connection
technology and TCP/IP routing with a conventional Ethernet interface in one
compact and convenient package. ADSL connection technology enables many
interactive multi-media applications such as video conferencing and collaborative
computing.
The Router is easy to install and use. The DSL-500 connects to an Ethernet LAN
via a standard Ethernet 10BASE-T interface using RJ-45 connectors. The ADSL
connection is made using ordinary twisted-pair telephone line with standard
RJ-11 connectors. This arrangement means that several PCs can be networked
and connected to the Internet using a single WAN interface and IP address.
The Router supports transparent bridging and can be used for IP packet routing
over the Internet. Cost saving features of the Router such as NAT (Network
Address Translator) and DHCP (Dynamic Host Configuration Protocol) improve
administration efficiency and improve security. The advanced security
enhancements, packet filtering and port redirection, can help protect your
network from potentially devastating intrusions by malicious agents from outside
your network.
ADSL Technology
Asymmetric Digital Subscriber Line (ADSL) is an access technology that utilizes
ordinary copper telephone lines to enable broadband high-speed digital data
transmission and interactive multimedia applications for business and
residential customers. The use of existing copper telephone lines forgoes the need
for upgrading lines or adding expensive new cable.
ADSL devices use digital coding techniques that greatly increase the potential
capacity of phone lines without interfering with regular telephone services. For
the ADSL user, this means much faster data communications and the potential
for interactive video capabilities. ADSL devices make it possible to enjoy benefits
such as high-speed Internet access, telecommuting (remote LAN access),
collaborative computing, distance learning, movies on demand and multi-player
1
DSL-500 ADSL Router User’s Guide
video gaming, without experiencing any loss of quality or disruption of voice/fax
telephone capabilities.
ADSL provides a dedicated service over a single telephone line operating at
speeds of up to 8 Mbps downstream (to the user) and up to 640 Kbps upstream
depending on local telephone line conditions. These conditions are ideal for many
user applications. A secure point-to-point connection is established between the
user and the central office of the local telephone service provider. The user is
always connected thus eliminating dial-up time and simplifying connectivity
issues.
Product Features
The DSL-500 ADSL Router utilizes the latest ADSL enhancements and router
technologies to provide a robust Internet gateway suitable for most small to
medium sized offices.
PPP (Point-to-Point Protocol) Security
The DSL-500 ADSL Router supports PAP (Password Authentication Protocol)
and CHAP (Challenge Handshake Authentication Protocol) for PPP connections.
DHCP Support (Dynamic Host Configuration Protocol)
DHCP (Dynamic Host Configuration Protocol) automatically and dynamically
assigns al LAN IP settings to each host on your network. This eliminates the
need to reconfigure every host whenever changes in network topology occur.
Network Address Translation (NAT)
For small office environments, the DSL-500 allows multiple users on the LAN to
access the Internet concurrently through a single Internet account. This provides
Internet access to everyone in the office for the price of a single user.
NAT improves network security in effect by hiding the private network behind
one global and visible IP address. NAT address mapping can also be used to link
two IP domains via a LAN-to-LAN connection.
TCP/IP (Transfer Control Protocol/Internet Protocol)
The DSL-500 supports TCP/IP protocol, the language used for the Internet. It is
compatible with access servers manufactured by major vendors.
RIP-1/RIP-2
The DSL-500 supports both RIP-1 and RIP-2 exchanges with other routers. Using
both versions lets the Router to communicate with all RIP enabled devices.
2
DSL-500 ADSL Router User’s Guide
Static Routing
This allows you to select a data path to a particular network destination that will
remain in the routing table and never “age out”. If you wish to define a specific
route that will always be used for data traffic from your LAN to a specific
destination within your LAN (for example to another router or a server) or
outside your network (to a ISP defined default gateway for instance).
Default Routing
This allows you to choose a default path for incoming data packets for which the
destination address is unknown. This is particularly useful when if the Router
functions as the sole connection to the Internet.
ATM (Asynchronous Transfer Mode)
The DSL-500 supports Bridged Ethernet over ATM (RFC1483), IP over ATM
(RFC1577) and PPP over ATM (RFC 2364). The Router can support up to eight
Virtual Circuit Connections (VCCs).
Precise ATM Traffic Shaping
Traffic shaping is a method of controlling the flow rate of ATM data cells. This
function helps to establish the Quality of Service for ATM data transfer.
G.hs (Auto-handshake)
This allows the Router to automatically choose either the G.lite or G.dmt ADSL
connection standards.
High Performance
Very high rates of data transfer are possible with the Router. Up to 8 Mbps
downstream bit rate using the G.dmt.
Full Network Management
The DSL-500 incorporates SNMP (Simple Network Management Protocol)
support for web-based management and text-based network management via an
RS-232 or Telnet connection.
Telnet Connection
The Telnet enables a network manager to access the Router’s management
software remotely.
Easy Installation
The DSL-500 uses a web-based graphical user interface program for convenient
management access and easy set up. Any common web browser software can be
used to manage the Router.

Prepare for Installation
For the smoothest possible installation, assemble all the equipment and
information needed to set up the Router and establish the initial ADSL
connection before you begin. Everything needed for the installation is listed and
discussed in this chapter.
Microfilters and Splitters
Most ADSL clients will be required to install a simple device that prevents the
ADSL line from interfering with regular telephone services. These devices are
commonly referred to as microfilters or sometimes called (inaccurately) line
splitters. They are easy to install and use standard telephone connectors and
cable.
Some ADSL service providers will send a telecommunications technician to
modify the telephone line, usually at the point where the phone line enters the
building. If a technician has divided or split your telephone line into two separate
lines - one for regular telephone service and the other for ADSL – then you do not
need to use any type of filter device. Follow the instructions given to you by your
ADSL service provider about where and how you should connect the Modem to
the ADSL line.

Unless you are instructed to use a “line splitter” (see below), it will be necessary
to install a microfilter (low pass filter) device for each telephone or telephone
device (answering machines, Faxes etc.) that share the line with the ADSL
service. Microfilters are easy-to-install, in-line devices, which attach to the
telephone cable between the telephone and wall jack. Microfilters that install
behind the wall plate are also available. A typical in-line microfilter installation
is shown in the diagram below.
Microfilter Installation
Note: Do not install the microfilter between the Modem and the telephone jack.
Microfilters are only intended for use with regular telephones, Fax machines and other
regular telephone devices.

Line Splitter
If you are instructed to use a “line splitter”, you must install the device between
the Modem and the phone jack. Use standard telephone cable with standard RJ11 connectors. The splitter has three RJ-11 ports used to connect to the wall jack,
the Modem and if desired, a telephone or telephone device. The connection ports
are typically labeled as follows:
Line - This port connects to the wall jack.
ADSL – This port connects to the Modem.
Phone – This port connects to a telephone or other telephone device.
The diagram below illustrates the proper use of the splitter.

Additional Requirements
You will need a PC (referred to in this guide as the Manager PC) to set up and
use the Router. In addition, it will be necessary to configure the device using
information provided by your ADSL service provider. This information is used to
establish the parameters of the ADSL connection and identify the Router on the
WAN. The requirements for the PCs on your LAN are summarized below.
PC WORKSTATION REQUIREMENTS
You can use the Router with PCs that meet the conditions discussed here.
Operating System
The web-based management software can be used on PCs running one of the
following operating systems:
Microsoft Windows 95 Windows 98 SE
Windows 2000
Windows 98
Windows NT 4.x
Windows Me
Web Browser
Any common web browser such as Microsoft Internet Explorer or Netscape
Navigator can be used to configure the Router using the embedded web-based
management software.
Ethernet Adapter
All PCs using the Router for Internet access, including the Manager PC, must
have an Ethernet NIC (Network Interface Card) installed. Each computer on the
internal network must have TCP/IP Protocol enabled. If you have an existing
Ethernet set up, the PCs should already meet this requirement.
ADSL SETTINGS
Each ADSL client on a DSL network has a unique integer pair used by the DSL
network managers to provide dedicated bandwidth on the ATM network
backbone. This pair of numbers is sometimes called the VPI/VCI pair.
The Virtual Path Identifier (VPI) and a Virtual Channel Identifier (VCI)
must be entered during the configuration process.

DSL-500 ADSL Router User’s Guide
CONNECTION METHOD
It is necessary to know the connection method used for the ADSL connection. The
connection method is also known as the ADSL Protocol, Encapsulation Protocol
or Encapsulation Method. These protocols are defined by “RFCs” which are
internationally recognized standards for networking protocols. You will be
required to configure the Router to use the correct method. PPP connections
require account information to be entered and stored in the device. Bridged
Ethernet connections require that the IP settings be set manually.
The Router supports three connection methods:
♦ PPP over Ethernet (RFC 2516) used by default
♦ PPP over ATM (RFC 2364)
♦ Ethernet over ATM (RFC 1483)
CONNECTION METHOD
Protocol:
RFC 2516 Point-to-Point Protocol over Ethernet
RFC 1483 Multi-protocol Encapsulation over ATM
RFC 2364 Point-to-Point Protocol over ATM
PPP CONNECTIONS (RFC 2516 & RFC 2364)
Account Information (User Name and Password)
For PPP connections, a User Name and Password for the user account are needed
to connect to the service provider’s network.
ACCOUNT INFORMATION (PPP Connections Only)
User Name:

25
DSL-500 ADSL Router User’s Guide
BRIDGED ETHERNET CONNECTIONS (RFC 1483)
For Bridged Ethernet connections it will be necessary to give the Router a global
IP address and default gateway.
Global IP Address
If the connection method used is Ethernet over ATM (RFC 1483), a unique global
IP address will be needed for the Router. The assigned global IP address must be
entered only if the connection method used is Ethernet over ATM (RFC 1483).
When using the default connection method, PPP over Ethernet (RFC 2516), a
global IP address will be assigned automatically during the connection process.
Default Gateway IP Address
Some network service providers require that a default gateway router be used by
the Router to connect to their network backbone. If this is the case, the IP
address of the default gateway (router) must be entered during the configuration
of the device.
BRIDGED ETHERNET CONNECTIONS
Global IP Address:
______ : ______ : ______ : ______
Default Gateway IP Address: ______ : ______ : ______ : ______
DNS SETTINGS
Your DSL service provider should give you DNS settings. These settings should
include the IP address of the DNS server as well as its domain name. You must
enter these in the DHCP Configuration menu.

Hardware Installation
This chapter discusses the various connections you will need to make in order to
use the Router.
When selecting the location for the Router, allow room to access the connections
on the rear panel. You will want to place the Router so that you will be able to
see the LED indicators on the front panel. Also allow some space above the
Router for ventilation to avoid problems with overheating.
It may be convenient for you locate the Router near the PC you intend to use for
initial configuration of the Router. For initial configuration of the device you may
need convenient access to the RS-232 serial port on the rear panel. The RS-232
serial port is intended for use with text-based console management software for
the initial configuration and for out-of-band management of the Router. Whether
it is necessary to use an RS-232 console manager for first time set up depends on
how you allocate IP addresses on your network. Read Chapter 4, First Time Set
Up to help you decide how best to use the Router on your network.
Connect the Power
Insert the AC Power Adapter cord into the power receptacle located on the rear
panel of the Router and plug the adapter into a nearby power source. You should
see the Power LED indicator light up and remain lit.
Connect ADSL Line
Use the twisted-pair ADSL cable (standard telephone cable) included with the
Router to connect it to your telephone line. Simply plug one end of the cable into
the ADSL port (RJ-11 receptacle) on the rear panel of the Router and insert the
other end into the wall jack. The ADSL connection is the WAN interface. It links
the Router to the network service provider’s backbone infrastructure. This is the
Router’s access point to the Internet.
The Router must undergo a negotiation process to establish the terms of the
ADSL connection. During this negotiation the Status LED will light a steady
green, after which it will blink. If the ADSL line is disconnected, it will repeat
this process.
Connect Ethernet LAN to Router
The Router may be connected to any 10BASE-T Ethernet LAN. Connection to an
Ethernet concentrating device such as a switch or hub should use standard
twisted-pair cable with RJ-45 connectors. The RJ-45 port on the Router is a
27
DSL-500 ADSL Router User’s Guide
straight-through (MDI-X) connection. Follow standard Ethernet guidelines when
deciding what type of cable to use to make this connection. Use a normal crossed
cable when connecting the Router to a normal (MDI-X) port on a switch or hub.
Use a straight-through cable when connecting it to an uplink (MDI-II) port on a
hub or switch. When connecting the Router directly to a PC or server (MDI-II)
use a straight-through cable. A valid connection will be indicated by a steady
green Ethernet Link LED indicator.
The rules governing Ethernet cable lengths apply to the LAN to Router
connection. Be sure that the cable connecting the Ethernet LAN to the Router
does not exceed 100 meters.
The diagram below illustrates a typical Ethernet LAN to Router connection.
LAN to Router Connection

First Time Set Up
It will be convenient for most users to establish an initial ADSL connection for
one PC equipped with an Ethernet NIC (Network Interface Card). It is
recommended that you install and configure the Router using one non-networked
computer. This allows you to verify that the ADSL service is functioning and that
you are able to communicate with the device. Once the initial ADSL connection is
established, you can proceed to build an Ethernet LAN around the device or
incorporate it into an existing LAN. For convenience, the PC used to configure
the Router is henceforth referred to as the manager PC.
To further simplify things it is recommended that you use the Router’s web-based
management software for initial configuration. To communicate with the Router,
the manager PC must be connected to it via an Ethernet connection and have a
web browser installed. Furthermore, the manager PC must reside within the
same subnet as the Router. This can be done easily using the DHCP function of
the Router. The Router will act as a DHCP server by default. You can configure
the manager PC to obtain its IP settings from the Router by following the
procedure in the next section.
You should start by configuring the manager PC to obtain IP settings from the
Router. Next disconnect the manager PC from the network and connect it directly
to the Router with a straight-through Ethernet cable.
If you do not wish to change the existing IP settings of the manager PC, you can
change the IP address of the Router. For instructions for changing the Router’s
IP address read Chapter 6, LAN Setup, for more information.

The Manager PC can now use a web browser to communicate with the Router. Be
sure that the Manager PC is not configured to use a proxy server for Internet
access.
Note: Be sure that the Manager PC is not configured to use a proxy server in the Internet
settings. In Windows Internet Explorer, you can check if a proxy server is enabled using the
following procedure:
1. In Windows, click on the START button, go to Settings and choose Control Panel.
2. In the Control Panel window, double-click on the Internet Options icon.
3. Click the Connections tab and click on the LAN Settings button.
4. Verify that the “Use proxy server” option is NOT checked. If it is checked, click in the
checked box to deselect the option and click OK.
To use the web-based management software, launch a suitable web browser and
direct it to the IP address of the Router. Type in http:// followed by the default IP
address, 192.168.0.1 in the address bar of the browser. The URL in the address
bar should read: http://192.168.0.1.
In the page that opens, click on the Login to web-based management module
button:
A new window will appear and you will be prompted for a user name and
password to access the web-based manager. Use the default user name admin
and password admin for first time set up. You should change the web-based
manager access user name and password once you have verified that a
connection can be established. The user name and password allows any PC
within the same subnet as the Router to access the web-based manger.
33
DSL-500 ADSL Router User’s Guide
NOTE: Do not confuse the user name and password used to access the web-based
manager with the ADSL account user name and password needed for PPP connections
to access the ADSL or network service provider’s network.
Logging in will bring up the main page of the web-based management module.
Click the DSL-500 folder in the main window. This folder will open revealing the
management menu options. These menus are used to configure the Router for

steps to first establish the WAN connection. The remaining features not directly
concerned with establishing the initial connection are explained in Chapter 5,
Web-based Management.
Web-based Manager Main Menu
Configure the WAN Connection
Now that you have accessed the web-based manager, you must configure the
Router for the ADSL connection (VPI/VCI pair) and provide other information to
establish the WAN connection. The other information provided depends on the
type of WAN connection you have. For PPPoE and PPPoA connections, you will
need to provide a User Name and Password used for authentication purposes.
For “Bridged Ethernet” (RFC 1483) connections a static IP address must be used.
It is necessary to supply IP settings for the WAN connection and other
information discussed in Chapter 2, Prepare for Installation. All connection
methods available to the Router are discussed in this chapter, beginning with
PPPoE connections. PPPoE is the most commonly used protocol to provide ADSL
connection and is the default method used by the Router. For a more detailed
discussion of the various menu items in the connection configuration windows,
see Chapter 5, Web-based Management.
If you are using either a PPPoA or Bridged Ethernet (RFC 1483) connection it
will be necessary to change the connection method. Please read the section

If your network account is billed according to the amount of time the Router is
actually connected to the Internet, enter an appropriate Idle Time value (in
seconds). This will disconnect the Router after the WAN connection has been idle
for the amount of time specified.
PPP Information
This field provides information regarding the status of the Router’s connection to
the WAN. The global IP Address for the Router should be assigned
automatically by the network service provider’s PPP server. The Connection
Status will read Disconnect until the Router has established the WAN
connection.
Connect to WAN
If you have enabled the Connect on Demand feature, the Router will have
established the WAN connection upon restarting.
If the Connect on Demand feature has been disabled, click the Connect button to
initiate the PPP connection via the ADSL WAN interface. The “handshake”
process will take a few seconds.
In the PPPoE or PPPoA Configuration widow, viewing the Connection Status
Connected, under PPPoA Information will indicate a valid connection. A valid
ADSL connection can also be confirmed by observing the LED indicators on the
front panel of the device.

Router Functions
The DHCP and NAT functions of the Router allows the network manager to more
easily manage IP addresses and subnets, and enhance network security by
presenting only one global IP address to the Internet. This section discusses how
to use these conventional routing functions.
DHCP
The Dynamic Host Configuration Protocol (DHCP) allows the Router to assign IP
addresses to all properly configured hosts on the network. Dynamic IP
assignment alleviates the need for the network administrator to maintain and
monitor IP address assignments and simplifies IP use because IP address are
automatically assigned when a station powers-on. Click on the DHCP
Configuration button to see the DHCP menu.
IMPORTANT: If you use DHCP to set your local IP addresses, the IP settings of all
stations on the network must be either manually configured to 0.0.0.0 or, select the
“Obtain an IP address automatically” option under the TCP/IP Properties tab in the
Network menu. See the Configure the Manager PC section at the beginning of Chapter
4 for more explicit instructions.
DHCP Configuration Window
In the DHCP Configuration window you define the following:
Start IP Address
This is the base (starting) address for the IP pool of unassigned IP addresses.
End IP Address
This is the last address of the contiguous IP address range to be used by the
Router for DHCP function.
51
DSL-500 ADSL Router User’s Guide
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.
Default Gateway
This specifies the Gateway IP Address that will be assigned to and used by the
DHCP clients.
Leased Time
This specifies the amount of time (in seconds) a client can lease an IP address,
from the dynamically allocated IP pool. A value of 4294967295 means the lease is
permanent.
DNS Server IP
Domain Name Service (DNS) servers are used on the Internet to match the
Uniform Resource Locator (URL) for a website to its Internet IP address. For
example, the URL: www.cnn.com, is a pseudonym for the IP address:
207.25.71.25. DNS entries allow users to access resources using URLs instead of
IP addresses.
You may enter any Internet DNS server IP address available through the WAN
connection. This address should be provided by your network service provider.
(Note that without a DNS server IP, internet sites will only be available using IP
addresses and will not be available using URLs.)
State
This toggles Disable and Enable for DHCP function.
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. The Router allows up to 128
host IP addresses.
NAT has two major benefits. First, NAT allows many users to access the Internet
using 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 an added degree of security by
hiding your private network behind one IP address. The NAT function will
normally only allow incoming packets that are generated in response to a request
from a host within the LAN.
If your network uses web servers, FTP servers or other proxies used for data
requests from outside the private network, you can use NAT in conjunction with
52
DSL-500 ADSL Router User’s Guide
Port Redirection to allow appropriate use of your servers by outside users. See
the section on Port Redirection for more information.
For the purposes of network administration, NAT is almost indispensable. Hosts
and servers on the internal network can be moved easily. Using NAT together
with DHCP can greatly reduce the workload of a network manager while
allowing tremendous flexibility.
NAT Configuration Window
The NAT function is enabled by default on the Router. If you want to disable
NAT, open the NAT Configuration window, select disabled in the NAT Function
pull-down menu. Click the OK button to implement your choice. There are
security risks associated with disabling NAT, so it is important that you have
other network protection mechanisms in place before you do this.
53
DSL-500 ADSL Router User’s Guide
Security Features
Network security is an unfortunate necessity for any network connected to the
Internet. Protection of sensitive information and proprietary assets on your
private network should be designed into the network infrastructure from the
beginning. If you are not already, it is recommended that you become familiar
with network security issues and the strategies available to help reduce risks
from outside as well as from within your LAN. The Router provides features that
can enhance your network security and should be used in concert with other
security provisions, such as virus scanning software for all workstations, the use
of proxy servers and stateful inspection methods.
Advanced Filtering and Firewall
One of the most important elements of any network security implementation is
the firewall. Packet filtering is a basic firewall security measure that should be
used on any network that is exposed to security risk. A packet filter system
examines data packets and scrutinizes them for the purpose of controlling
network access. Filtering rules determine whether or not to allow access through
the Router from either side of the gateway. The rules are created and controlled
by the network administrator and can be precisely defined. These rules are used
to block access to the network from the outside, or deny access to the WAN from
within the network. The Router uses filtering rules to examine data packet
headers for specific information. Packets passing through the Router that do not
meet the criteria specified by the rule set are dropped.
In order to improve network security without severely limiting network
efficiency, it is important to carefully plan the sets of access rules. Effective
implementation of packet filtering requires detailed knowledge of network
services and communication protocols. An overly complicated filtering scheme
can adversely effect routing performance, while an inadequate set of rules may
needlessly compromise security.
Packet filtering can be used in conjunction with NAT, port redirection and proxy
servers to help provide basic firewall protection. However, these measures do not
address many security issues and should be used as only one part of an overall
network security strategy. It is important to remember that IP packet filtering
examines only the packet header and is not concerned with application
information. Therefore, packet filtering does not protect against higher-level
security threats that may operate at the application or other level.
Filtering rules can be precisely defined based upon source and destination IP
address, as well as port and protocol information. Up to twelve filter sets can be
used; each set contains up to seven filtering rules subsets.
54
DSL-500 ADSL Router User’s Guide
Advanced Filtering and Firewall (Screen #1)
To define the filter rule sets, click on the Advanced Filtering and Firewall button
to bring up the first window. Choose Enable in the IP Filter pull-down menu
and click the OK button to enable IP filtering. Then click on the set number you
wish to configure to proceed to the next window.
55
DSL-500 ADSL Router User’s Guide
Advanced Filtering and Firewall (Screen #2)
In the second Advanced Filtering window you can supply a comment or name of
up to 15 characters for the set in the Set Comments field. Click the OK button
to save the comments, then click on the number of the subset you want to
configure to proceed to the next window.
56
DSL-500 ADSL Router User’s Guide
Advanced Filtering and Firewall (Screen #3)
In the third Advanced Filtering window you will define the rule applied for the
chosen subset. Again you can supply a name for the subset in the Comment field
and click the box on the right to enable the Filter Rule.
In the Pass or Block field select the action to be performed on the IP packets,
the default is Pass Immediately. All blocked packets will be dropped.
In the Direction field choose either In or Out from the pull down menu. You can
block IP packets from coming into the network, by selecting In, blocking packets
from a specific IP address for example. Or you can block packets from a specific
IP address or subnet from leaving the LAN by selecting Out, for example, to block
Internet access for a specific host.
The Protocol field allows you to block packets based on the protocol used. You
may choose to block ICMP, TCP or UDP transmissions from the pull-down menu.
You must next specify the Source and Destination IP Addresses as well as
their Subnet Mask. This will block the packets from or destined to any specified
IP address from passing through the Router.
Finally you can specify individual protocol ports or an entire range of protocol
ports to be blocked for the Source or Destination. Type the Start Port number
57
DSL-500 ADSL Router User’s Guide
in either the Source or Destination row. If there is no port specified in the Start
Port column, the filter rule will be ignored. Use the <, >, = or ≠ in the pull down
menu to specify the port or range of ports to be filtered. Use the following guide
to define the port or port range:
< : specifies the port numbers less than and equal to the Start Port number
> : specifies the port numbers greater than and equal to the Start Port number
= : sets the port number equal to the Start Port if there is no End Port
specified; if an End Port number is specified, this defines a range of ports to
filter. The range is defined as the port numbers between the Start Port and
End Port, including the Start and End Port numbers.
≠ : the port number does not equal to the Start Port if there is no End Port
specified; if an End Port number is specified, this defines a range of ports not
to filter. The range is defined as the port numbers between the Start Port and
End Port, including the Start and End Port numbers.
Port Redirection
Port Redirection Window
The Port Redirection feature of the Router is used in conjunction with NAT to
improve security and efficiency. Port redirection can be used to direct potentially
hazardous packets to a proxy server outside your firewall. For example, it is
common practice to direct HTTP packets to a designated HTTP server in the
DMZ. Other common applications might include directing incoming SMTP
packets to an Email server for data scrutiny and improved network efficiency.
Click the Add button in the Port Redirection window to access the Redirect Port
menu.
58
DSL-500 ADSL Router User’s Guide
Redirect Port Window
The Redirect Port window presents five entry fields. The first field, Comment
can be used to assign an appropriate name to the new route, for our example we
will use the name HTTP Server. In the Internet Port field enter the designated
TCP or UDP protocol port number for the particular protocol packet you wish to
redirect. In our example an incoming HTTP packets use port 80. The local port is
the port used by the designated host on the LAN. In this case an HTTP server,
conventionally port 8080 is used for this purpose. Choose the protocol either TCP
or UDP from the pull-down Protocol menu, HTTP is defined within TCP. In the
Local Computer field supply the IP address of the local designated host
computer or device. Using our example you would enter the IP address of the
HTTP server.
Router Utility Functions
Once the Router configurations have been set, it is necessary to save the new
settings to memory. You may also upgrade the Router to use the latest firmware.
The procedures for saving settings and upgrading firmware are discussed here.
59

LAN Setup
The Router allows many possibilities for network layout. This gives the network
administrator much flexibility to decide how best to use it. One of the most
important decisions for the network administrator involves IP addressing on the
LAN. The easiest choice in most cases is to let the Router take care of it for you
using DHCP, which is done by default. This chapter discusses the various
alternatives for IP address assignment using the Router.
Assigning Network IP Addresses
The IP address settings, which include the IP address, subnet mask and gateway
IP address are the first and most important internal network settings that need
to be configured. The Router is assigned a default LAN IP address and subnet
mask. If you do not have a preexisting IP network and are setting one up now,
using the factory default IP address settings can greatly ease the setup process. If
you already have a preexisting IP network, you can adjust the IP settings for the
Router to fit within your existing scheme.
Using the Default IP Address
The Router comes with a preset default IP address setting of 192.168.0.1 for the
LAN port. There are two ways to use this default IP address, you can manually
assign an IP address and subnet mask for each PC on the LAN or you can
instruct the Router to automatically assign them using DHCP. The simplest
method is to use DHCP. The DHCP function is active by default.
Manual IP Address Assignment
You can manually set the IP address, subnet mask and default gateway on each
computer by performing the following steps for each PC on the network:
1. In Windows 95/98, click on the START button, go to Settings and choose
Control Panel.
2. In the window that opens, double-click on the Network icon.
3. Under the Configuration tab, select the TCP/IP component and click
Properties.
4. Choose the Specify an IP address option and edit the address settings
accordingly. Consult the table below for IP settings on a Class C network.
63
DSL-500 ADSL Router User’s Guide
Default Addressing Example
Host
IP Address
Subnet Mask
Gateway IP
Router
192.168.0.1
255.255.255.0
Computer #1
192.168.0.2
255.255.255.0
192.168.0.1
Computer #2
192.168.0.3
255.255.255.0
192.168.0.1
Computer #3
192.168.0.4
255.255.255.0
192.168.0.1
Please note that when using the default IP address as in the above example, the
first three numbers in the IP address must always be the same with only the
fourth number changing (for a Class C network). This is because the first three
numbers define the network IP address (all machines must belong to the same IP
network), while the last number denotes the host IP address (each computer
must have a unique address to distinguish it on the network). Also note that the
subnet mask is the same for all machines and the default gateway address is the
LAN IP address of the Router.
It is a good idea to make a note of each device’s IP address for reference during
troubleshooting or when adding new stations or devices.
Using DHCP
The second way to use the default settings is to allow the Router to automatically
assign IP addresses to your computers using DHCP. To do this, simply make sure
your computers’ IP addresses are set to 0.0.0.0 (under Windows, choose the
option Obtain an IP address automatically in the TCP/IP network component
described above). When the computers are restarted, their IP settings will
automatically be assigned by the Router. The Router is set by default to use
DHCP. See the discussion in Chapter 5 for information on how to use configure
the Router for DHCP.
Changing the IP Address of the Router
If you choose to change the IP address of the Router you will need to access the
device directly via the RS-232 connection using a terminal emulation interface
(such as Microsoft HyperTerminal used in the sample screen captures). Your
terminal parameters will need to be set to:
VT-100/ANSI compatible
Terminal keys enabled
9,600 baud
8 data bits
No parity
One stop bit
64
DSL-500 ADSL Router User’s Guide
Connect a standard RS-232 (DB-9 to DB-9) cable to the Router’s RS-232 port on
the rear panel, connect the other end to a PC with a terminal emulation program
already installed. Power on the Router and launch the emulation program. The
terminal emulator will display system information while the unit undergoes selftesting. When 192.168.0.1> appears on the screen the unit has completed its
self-test. In this mode, the default IP address 192.168.0.1 and an angle bracket
(“greater than”) will appear each time the Enter key is depressed.
HyperTerminal Interface (Boot Up)
To change the IP address of the Router type ip after the command prompt and
hit Enter. Be sure to type commands using all lower case letters as the console
interface is case sensitive. A new command prompt 192.168.0.1 ip> will
appear indicating that the unit is now ready to accept ip commands.
Type the following command series after the ip prompt: enable ethernet
followed by the new IP address to be assigned to the device as seen in the
example below.
65
DSL-500 ADSL Router User’s Guide
HyperTerminal Interface with new IP address
You must save the new IP address by typing the command series config save
and pressing Enter. This will save the new IP address for the Router and store it
in the device’s flash memory. You may now disconnect the terminal emulator and
access the device using the web-based management interface for configuration.
For more thorough instructions on using the out-of-band console manager, see
Chapter 7.
66
DSL-500 ADSL Router User’s Guide
7
Using the Console Manager
Settings for the Router can be configured via the RS-232 console port connection
using terminal emulation software such as Microsoft HyperTerminal included
with Microsoft’s operating systems. This chapter lists and describes a few of the
most essential command sets that might be used by the typical user. This chapter
is not intended to be a complete list of the commands available.
General Use
To use a terminal emulation interface with the device, the terminal parameters
will need to be set to:
VT-100/ANSI compatible
Terminal keys enabled
9,600 baud
8 data bits
No parity
One stop bit
With the correct parameters set and the RS-232 connection established you
should be able to use the keyboard to communicate with the device. If the Router
is powered on when the terminal interface appears, depress the Enter key to
bring up the initial prompt. This will be the IP address of the device. For
information about changing the IP address, please read the section in Chapter 6.
If at any time you want to view a list of commands available in the particular
mode you are currently operating, type help and press Enter. This will bring up
a list of the commands available in the current mode. For example, type help
after the initial IP address prompt and you will see a menu similar to this:
ap

DSL-500 ADSL Router User’s Guide
To see a list of available commands and command syntax along with brief
explanation of the command, type help all and depress Enter. Remember that
the console interface commands are case sensitive.
Typing any of the commands listed above and depressing Enter will put the
console interface into that command mode. For example, form the IP address
prompt type ip and depress Enter. This will put the interface into “ip” where it
can now accept ip mode commands. While in ip mode or any other command
mode you may again type help or help all to list the commands available in that
mode. You will see the command appear after the IP address and before the
“greater than” sign. If you type help in ip mode you would see a menu such as
this:
?
arp
config
device
disable
enable
help
ipatm
nat
norelay
ping
relay
rip
route
routes
snmp
stats
subnet
version
If you at any time wish to return to the original undefined command prompt (the
first IP address prompt), type home and depress Enter and you will again see the
IP address prompt.
The commands restart, uptime and version are not command modes. The
restart command will restart (reboot) the Router. Remember that any changes
made to the configuration must be saved before the Router is restarted or the
changes will be lost. The uptime and version commands simply list the uptime
(amount of time the Router has been continuously operating) and the software
version of the unit.
Saving Changes
To save changes made to the Router configuration type config save and press
Enter, the current settings will be saved to nonvolatile RAM.
Finding the Password
If you forget the user name and password that allows you to access the web-based
manager you can retrieve this information using the console terminal interface.
To do this type flashfs cat initweb and you will see the user name and
password listed.

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 it has a valid IP address. Even
if you will not use the WAN port (ADSL port), you should, at the very least, make
sure the Ethernet 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 for routing data between networks
within any site (often referred to as “subnetworks” or “subnets”). 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.
71
DSL-500 ADSL Router User’s Guide
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.

Note: 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.
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 IPcapable port or interface — connected directly to that network.
72
DSL-500 ADSL Router User’s Guide
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 Internetassigned 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
A
B
C
Beginning
Address
10.0.0.0
172.16.0.0
192.168.0.0
Ending Address
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.

DSL-500 Firmware Upgrade Utility
You can update system firmware using the DSL-500 Firmware Upgrade Utility.
To upgrade the Router’s firmware you must have installed this software on the
PC you wish to use for this purpose. Install the utility by clicking the file titled
setup.exe located on the Installation CD-ROM. It will be installed automatically.
It is recommended that the PC be directly connected to the Router using a
crossed cable, however you may upgrade it through the LAN from a remote host.
You also need to download the latest firmware version file from the D-Link web
site to the PC on which you will use the Upgrade Utility. Instructions for
downloading the firmware are located on the web site at www.dlink.com.
To launch the DSL-500 Firmware Upgrade Utility, click on the icon. Allow a few
moments for the software to discover the Router on the network. After the
discovery phase the following window will appear. You will see all the DSL-500
Routers on your network. You can identify individual devices by either its IP
address or its MAC address. Select the device you wish to upgrade by double
clicking on it.
When you select a Router to upgrade you will be prompted for a password. The
default password is admin. If you want to change the password, you can change
it using the console manager interface as described in Chapter 6.
74
DSL-500 ADSL Router User’s Guide
Enter the password and click OK.
In the new window you will see the MAC address of the Router and the IP
address of the PC you are using. The PC and the Router must be on the same
subnet for the upgrade to be completed. The upgrade utility will suggest a new IP
address to be temporarily assigned to the device during the firmware upgrade
procedure. Check the suggested IP address listed for the Router to be sure that it
does not conflict with any existing IP addresses on your network. To change the
temporary IP address of the Router, type in an available IP address in the space
provided. You should change only the host portion of the address.
To upload the new firmware to the selected Router click the ‘Upgrade’ button.
The utility will automatically load the new firmware. During the upgrade process
it is important that you allow the entire file to load onto the device. Do not turn
off the Router while the flash memory is being updated. A warning will appear
during the upgrade reminding you not to power off the device.
When the new firmware has been successfully loaded a new window will inform
you of the upgrade and tell you that the Router has been restarted. Click OK to
proceed.
