Limited Warranty
Hardware:
D-Link warrants each of its hardware products to be free from defects in workmanship and materials under normal use and service for a
period commencing on the date of purchase from D-Link or its Authorized Reseller and extending for the length of time stipulated by the
Authorized Reseller or D-Link Branch Office nearest to the place of purchase.
This Warranty applies on the condition that the product Registration Card is filled out and returned to a D-Link office within ninety (90)
days of purchase. A list of D-Link offices is provided at the back of this manual, together with a copy of the Registration Card.
If the product proves defective within the applicable warranty period, D-Link will provide repair or replacement of the product. D-Link
shall have the sole discretion whether to repair or replace, and replacement product may be new or reconditioned. Replacement product
shall be of equivalent or better specifications, relative to the defective product, but need not be identical. Any product or part repaired by
D-Link pursuant to this warranty shall have a warranty period of not less than 90 days, from date of such repair, irrespective of any earlier
expiration of original warranty period. When D-Link provides replacement, then the defective product becomes the property of D-Link.
Warranty service may be obtained by contacting a D-Link office within the applicable warranty period, and requesting a Return Material
Authorization (RMA) number. If a Registration Card for the product in question has not been returned to D-Link, then a proof of purchase
(such as a copy of the dated purchase invoice) must be provided. If Purchaser's circumstances require special handling of warranty
correction, then at the time of requesting RMA number, Purchaser may also propose special procedure as may be suitable to the case.
After an RMA number is issued, the defective product must be packaged securely in the original or other suitable shipping package to
ensure that it will not be damaged in transit, and the RMA number must be prominently marked on the outside of the package. The
package must be mailed or otherwise shipped to D-Link with all costs of mailing/shipping/insurance prepaid. D-Link shall never be
responsible for any software, firmware, information, or memory data of Purchaser contained in, stored on, or integrated with any product
returned to D-Link pursuant to this warranty.
Any package returned to D-Link without an RMA number will be rejected and shipped back to Purchaser at Purchaser's expense, and
D-Link reserves the right in such a case to levy a reasonable handling charge in addition mailing or shipping costs.
Software:
Warranty service for software products may be obtained by contacting a D-Link office within the applicable warranty period. A list of
D-Link offices is provided at the back of this manual, together with a copy of the Registration Card. If a Registration Card for the product
in question has not been returned to a D-Link office, then a proof of purchase (such as a copy of the dated purchase invoice) must be
provided when requesting warranty service. The term "purchase" in this software warranty refers to the purchase transaction and
resulting license to use such software.
D-Link warrants that its software products will perform in substantial conformance with the applicable product documentation provided by
D-Link with such software product, for a period of ninety (90) days from the date of purchase from D-Link or its Authorized Reseller.
D-Link warrants the magnetic media, on which D-Link provides its software product, against failure during the same warranty period.
This warranty applies to purchased software, and to replacement software provided by D-Link pursuant to this warranty, but shall not

DSL-502T DSL Router User’s Guide
About This User’s Guide
This user’s guide provides instructions on how to install the DSL-502T ADSL Router and use it to connect a
computer or Ethernet LAN to the Internet.
If you are using a computer with a functioning Ethernet port or an available USB port, the quickest and easiest
way to set up the DSL-502T is to insert the Installation CD into the CD-ROM drive of your computer and follow
the instructions provided in the Quick Installation Guide. Alternatively, you can click the “Install DSL-502T”
link on the initial pop-up menu that appears shortly after inserting the CD and follow the instructions as they are
presented. If the menu fails to appear, explore the CD, find the file “dsl502t.exe” and double-click it to launch
the installation software.
Before You Start
Please read and make sure you understand all the prerequisites for proper installation of your new Router. Have
all the necessary information and equipment on hand before beginning the installation.
Installation Overview
The procedure to install the Router can be described in general terms in the following steps:
1.
Gather information and equipment needed to install the device. Before you begin the actual installation
make sure you have all the necessary information and equipment.
2.
Install the hardware, that is, connect the cables (Ethernet and telephone) to the device and connect the
power adapter.
3.
Check the IP settings on your computer and change them if necessary so the computer can access the
web-based software built into the Router.
4.
Use the web-based management software to configure the device to suit the requirements of your ADSL
account.
Installation Requirements
In order to establish a connection to the Internet it will be necessary to provide information to the Router that
will be stored in its memory. For some users, only their account information (Username and Password) is
required. For others, various parameters that control and define the Internet connection will be required. You can
print out the two pages below and use the tables to list this information. This way you have a hard copy of all the
information needed to setup the Router. If it is necessary to reconfigure the device, all the necessary information
can be easily accessed. Be sure to keep this information safe and private.
Low Pass Filters
Since ADSL and telephone services share the same copper wiring to carry their respective signals, a filtering
mechanism may be necessary to avoid mutual interference. A low pass filter device can be installed for each
telephone that shares the line with the ADSL line. These filters are easy to install passive devices that connect to
the ADSL device and/or telephone using standard telephone cable. Ask your service provider for more
information about the use of low pass filters with your installation.
Operating Systems
The DSL-502T uses an HTML-based web interface for setup and management. The web configuration manager
may be accessed using any operating system capable of running web browser software, including Windows 98
SE, Windows ME, Windows 2000, and Windows XP.
ix
DSL-502T DSL Router User’s Guide
Web Browser
Any common web browser can be used to configure the Router using the web configuration management
software. The program is designed to work best with more recently released browsers such as Opera, Microsoft
Internet Explorer® version 5.0, Netscape Navigator® version 4.7, or later versions. The web browser must have
JavaScript enabled. JavaScript is enabled by default on many browsers. Make sure JavaScript has not been
disabled by other software (such as virus protection or web user security packages) that may be running on your
computer.
Ethernet Port (NIC Adapter)
Any computer that uses the Router must be able to connect to it through the Ethernet port on the Router. This
connection is an Ethernet connection and therefore requires that your computer be equipped with an Ethernet
port as well. Most notebook computers are now sold with an Ethernet port already installed. Likewise, most fully
assembled desktop computers come with an Ethernet NIC adapter as standard equipment. If your computer does
not have an Ethernet port, you must install an Ethernet NIC adapter before you can use the Router. If you must
install an adapter, follow the installation instructions that come with the Ethernet NIC adapter.
Additional Software
It may be necessary to install software on your computer that enables the computer to access the Internet.
Additional software must be installed if you are using the device a simple bridge. For a bridged connection, the
information needed to make and maintain the Internet connection is stored on another computer or gateway
device, not in the Router itself.
If your ADSL service is delivered through a PPPoE, PPPoA or CLIP (IPoA) connection, the information needed
to establish and maintain the Internet connection can be stored in the Router. In this case, it is not necessary to
install software on your computer. It may however be necessary to change some settings in the device, including
account information used to identify and verify the connection.
All connections to the Internet require a unique global IP address. For bridged connections, the global IP settings
must reside in a TCP/IP enabled device on the LAN side of the bridge, such as a PC, a server, a gateway device
such as a router or similar firewall hardware. The IP address can be assigned in a number of ways. Your network
service provider will give you instructions about any additional connection software or NIC configuration that
may be required.
About CLIP Connections (RFC 1577)
Classical IP over ATM (CLIP) connections may require global IP settings for the device. Your service provider
will give you IP settings information if needed. Some CLIP connections function like peer-to-peer connections
and therefore do not require IP settings on the WAN interface.

DSL-502T DSL Router User’s Guide
Information you will need from your ADSL service provider:
Username
This is the Username used to log on to your ADSL service
provider’s network. It is commonly in the form −
user@isp.com. Your ADSL service provider uses this to
identify your account.
Password
This is the Password used, in conjunction with the Username
above, to log on to your ADSL service provider’s network.
This is used to verify the identity of your account.
Connection Protocol
This is the method your ADSL service provider uses to send
and receive data between the Internet and your computer.
Your Modem supports the following connection protocols:
PPPoE, PPPoA, PPPoA with DHCP, Bridge, and CLIP
(IPoA).
Modulation Type
ADSL uses various standardized modulation techniques to
transmit data over the allotted signal frequencies. Some
users may need to change the type of modulation used for
their service. The default DSL modulation (MMODE) used for
the Router automatically detects all types of ADSL
modulation. However, if you are instructed to specify the
modulation type used for the Router, you have three
alternatives: G.LITE, G.DMT and T1.413
Security Protocol
This is the method your ADSL service provider will use to
verify your Username and Password when you log on to their
network. Your Modem supports the PAP and CHAP
protocols.
VPI
This is the Virtual Path Identifier (VPI). It is used in
conjunction with the Virtual Channel Identifier (VCI) below, to
identify the data path between your ADSL service provider’s
network and your computer.
VCI
This is the Virtual Channel Identifier (VCI). It is used in
conjunction with the VPI above to identify the data path
between your ADSL service provider’s network and your
computer.

If your computer has an available USB port, you can
connect the DSL-502T to this USB port using a USB cable.
DHCP Client status
Your DSL-502T ADSL Modem is configured, by default, to
be a DHCP server. This means that it can assign an IP
address, subnet mask, and a default gateway address to
computers on your LAN. The default range of IP addresses
the DSL-502T will assign are from 192.168.1.2 to
192.168.1.254. Your computer (or computers) needs to be
configured to Obtain an IP address automatically (that is,
they need to be configured as DHCP clients.)
Record info here
It is recommended that your collect and record this information here, or in some other secure place, in case you
have to re-configure your ADSL connection in the future.
Once you have the above information, you are ready to setup and configure your DSL-502T ADSL Router.

Introduction
This section provides a brief description of the Router, its associated technologies and a list of Router features.
Router Description and Operation
The DSL-502T ADSL Router is designed to provide a simple and cost-effective ADSL Internet connection for
individual computers through either the Ethernet or USB ports, or use it to bridge your Ethernet LAN to the
Internet. The DSL-502T combines the benefits of high-speed ADSL technology and LAN IP management in one
compact and convenient package. ADSL technology enables many interactive multi-media applications such as
video conferencing and collaborative computing.
The Router is easy to install and use. The DSL-502T connects to single computer or an Ethernet LAN via a
standard Ethernet interface. A single computer may also be connected through the USB port. The ADSL
connection is made using ordinary twisted-pair telephone line with standard connectors. Multiple PCs can be
networked and connected to the Internet using a single Wide Area Network (WAN) interface and single global
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 for your private network. 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.
What is ADSL?
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.
ADSL greatly increases the signal carrying capacity of copper telephone lines without interfering with regular
telephone services. For the ADSL user, this means faster downloads and more reliable connectivity. ADSL
devices make it possible to enjoy benefits such as high-speed Internet access 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
and up to 640 Kbps upstream, depending on local telephone line conditions. A secure point-to-point connection
is established between the user and the central office of the service provider.
D-Link ADSL devices incorporate the recommendations of the ADSL Forum regarding framing, data format,
and upper layer protocols.

DSL-502T ADSL Router User’s Guide
Router Features
The DSL-502T ADSL Router utilizes the latest ADSL enhancements to provide a reliable Internet portal suitable
for most small to medium sized offices. DSL-502T advantages include:
•
PPP (Point-to-Point Protocol) Security – The DSL-502T ADSL Router supports PAP (Password
Authentication Protocol) and CHAP (Challenge Handshake Authentication Protocol) for PPP connections.
•
DHCP Support – 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-502T 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-502T 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-502T supports both RIP-1 and RIP-2 exchanges with other routers. Using both
versions lets the Router to communicate with all RIP enabled devices.
•
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-502T supports Bridged Ethernet over ATM (RFC1483),
IP over ATM (RFC1577) and PPP over ATM (RFC 2364).
•
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 eight Mbps
downstream bit rate using the G.dmt.
•
Telnet Connection – The Telnet enables a network manager to access the Router’s management software
remotely.
•
Easy Installation – The DSL-502T 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.

Hardware Installation
The DSL-502T maintains three separate interfaces, an Ethernet, a USB and an ADSL interface. Place the Router
in a location where it can be connected to the various devices as well as to a power source. The Router should
not be located where it will be exposed to moisture or excessive heat. Make sure the cables and power cord are
placed safely out of the way so they do not create a tripping hazard. As with any electrical appliance, observe
common sense safety procedures.
The Router can be placed on a shelf or desktop, ideally you should be able to see the LED indicators on the front
if you need to view them for troubleshooting.
Power on Router
CAUTION: The Router must be used with the power adapter included with the device.
To power on the Router:
1.
Insert the AC Power Adapter cord into the power receptacle located on the rear panel of the Router and plug
the adapter into a suitable nearby power source.
2.
You should see the Power LED indicator light up and remain lit. The Status LED should light solid green
and begin to blink after a few seconds.
3.
If the Ethernet port is connected to a working device, check the Ethernet Link/Act LED indicators to make
sure the connection is valid. The Router will attempt to establish the ADSL connection, if the ADSL line is
connected and the Router is properly configured this should light up after several seconds. If this is the first
time installing the device, some settings may need to be changed before the Router can establish a
connection.
Factory Reset Button
The Router may be reset to the original factory default settings by depressing the reset button for a few seconds
while the device is powered on. Use a ballpoint or paperclip to gently push down the reset button. Remember
that this will wipe out any settings stored in flash memory including user account information and LAN IP
settings. The factory default IP address of the Router is 192.168.1.1 and the subnet mask is 255.255.255.0, the
default management Username is admin and the default Password is admin.

DSL-502T ADSL Router User’s Guide
Network Connections
Network connections are provided through the ADSL port, the Ethernet port and the USB port on the back of the
Router. See the Rear Panel diagram above and the illustrations below for examples. See Installing the USB
Driver above for a description of the USB driver installation procedure.
Connect ADSL Line
Use the ADSL cable included with the Router to connect it to a telephone wall socket or receptacle. 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 RJ-11 wall socket. If you are using a low pass filter device, follow the instructions included with the device
or given to you by your service provider. The ADSL connection represents the WAN interface, the connection to
the Internet. It is the physical link to the service provider’s network backbone and ultimately to the Internet.
Connect Router to Ethernet
The Router may be connected to a single computer or Ethernet device through the 10BASE-TX Ethernet port on
the rear panel. Any connection to an Ethernet concentrating device such as a switch or hub must operate at a
speed of 10/100 Mbps only. When connecting the Router to any Ethernet device that is capable of operating at
speeds higher than 10Mbps, be sure that the device has auto-negotiation (NWay) enabled for the connecting port.
Use standard twisted-pair cable with RJ-45 connectors. The RJ-45 port on the Router is a crossed port (MDI-X).
Follow standard Ethernet guidelines when deciding what type of cable to use to make this connection. When
connecting the Router directly to a PC or server use a normal straight-through cable. You should use a crossed
cable when connecting the Router to a normal (MDI-X) port on a switch or hub. Use a normal straight-through
cable when connecting it to an uplink (MDI-II) port on a hub or switch.
The rules governing Ethernet cable lengths apply to the LAN to Router connection. Be sure that the cable
connecting the LAN to the Router does not exceed 100 meters.
Hub or Switch to Router Connection
Connect the Router to an uplink port (MDI-II) on an Ethernet hub or switch with a straight-through cable as
shown in the diagram below:
If you wish to reserve the
uplink port on the switch or
hub for another device,
connect to any on the other
MDI-X ports (1x, 2x, etc.)
with a crossed cable.

Basic Router Configuration
The first time you setup the Router it is recommended that you configure the WAN connection using a single
computer making sure that both the computer and the Router are not connected to the LAN. Once the WAN
connection is functioning properly, you may continue to make changes to Router configuration including IP
settings and DHCP setup. This chapter is concerned with using your computer to configure the WAN
connection. The following chapter describes the various menus used to configure and monitor the Router
including how to change IP settings and DHCP server setup.
Wan Configuration Summary
1.
Connect to the Router To configure the WAN connection used by the Router it is first necessary to
communicate with the Router through its management interface, which is HTML-based and can be
accessed using a web browser. To access the management software your computer must be able to
“see” the Router. Your computer can see the Router if it is in the same “neighborhood” or subnet as the
Router. This is accomplished by making sure your computer has IP settings that place it in the same
subnet as the Router. The easiest way to make sure your computer has the correct IP settings is to
configure it to use the DHCP server in the Router. The next section describes how to change the IP
configuration for a computer running a Windows operating system to be a DHCP client.
2.
Configure the WAN Connection Once your are able to access the configuration software you can
proceed to change the settings required to establish the ADSL connection and connect to the service
provider’s network. There are different methods used to establish the connection to the service
provider’s network and ultimately to the Internet. You should know what Encapsulation and connection
type you are required to use for your ADSL service. It is also possible that you must change the PVC
settings used for the ADSL connection. Your service provider should provide all the information you
need to configure the WAN connection.
Configuring IP Settings on Your Computer
In order to configure your system to receive IP settings from the Router it must first have the TCP/IP protocol
installed. If you have an Ethernet port on your computer, it probably already has TCP/IP protocol installed. If
you are using Windows XP the TCP/IP is enabled by default for standard installations. Below is an illustrated
example of how to configure a Windows XP system to automatically obtain IP settings from the Router.
Following this example is a step-by-step description of the procedures used on the other Windows operating
systems to first check if the TCP/IP protocol has been installed; if it is not, instructions are provided for
installing it. Once the protocol has been installed you can configure the system to receive IP settings from the
Router.
For computers running non-Windows operating systems, follow the instructions for your OS that configure the
system to receive an IP address from the Router, that is, configure the system to be a DHCP client.
Note
If you are using this Router to provide Internet access for more than one computer, you
can use these instructions later to change the IP settings for the other computers.
However, you cannot use the same IP address since every computer must have its own
IP address that is unique on the local network.

Configure Connection 1 for PPPoA
PPP or Point-to-Point protocol is a standard method of establishing a network connection/session between
networked devices. Different forms of PPP include PPPoA and PPPoE (discussed below) involve an
authentication process that requires a username and password to gain access to the network. PPPoA (PPP over
ATM) as described in RFC 2364, is a method of using PPP on an ATM network. ATM is used for many types of
telecommunications services including ADSL.
To configure the WAN connection for PPPoA, perform the steps listed below. Some of the settings do not need
to be changed the first time the device is set up, but can be changed later if you choose.
Figure 3- 5. PPPoA Connection 1 Setup menu
To configure the default connection type (PPPoA) for Connection 1, follow the steps listed below. To change the
connection type of Connection 1 to an alternative type follow the instructions according to the desired type as
described below in Change the Connection Type.
1.
Click the Connection 1 button under WAN Setup to view the PPPoA Connection Setup menu
pictured in the example above.

If you are told to change the VPI or VCI values, type in the values given to you by your service
provider. Many users will be able to use the default settings.
5.
Leave the default QoS values if you are unsure or the ISP did not provide this information.
6.
Do not change the PCR or SCR values unless you are required to do so. If you are told to change these,
type in the values given to you by your service provider.
7.
Type the Username and Password used to verify the identity of your account. Typically, the Username
is an account number assigned by your ISP and appears in the form account#@serviceprovider.com,
while the Password may have been chosen by the account holder. For most users, the remaining settings
will not need to be changed. See your ISP for further information.
8.
Click the Apply button when you have entered all the information. The web browser will briefly go
blank. You are now finished changing setting for the primary WAN connection known as Connection 1.

Change the Connection Type
The default connection protocol used for the Router is Point-to-Point Protocol over ATM (PPPoA). The menu
used to configure a PPPoA connection is the first menu to appear when you click on the Connection 1 button in
the Setup menu. The alternative connection types supported by the Router are the PPPoE (PPP over Ethernet),
CLIP (Classical IP over ATM or IPoA), DHCP (for WAN), Static (IP for WAN), and Bridge connection types.
There are two ways you may configure the WAN connection to use these alternative types. You can create a
New Connection using the alternative connection type or you may configure the Connection 1 settings to use the
connection type of choice. This section describes how to change the Connection 1 settings to use a different
connection type. To change the Connection 1 settings to use a different connection type, follow the instructions
below according to the type of connection you want to use. To create and configure a New Connection, skip
ahead to Create a New Connection.
Configure Connection 1 for PPPoE
PPP or Point-to-Point protocol is a standard method of establishing a network connection/session between
networked devices. PPPoE configuration requires the same basic information as the previously discussed PPPoA
and both menus are nearly identical. It may be worthwhile for the user to change the default name of Connection
1 to something that states what connection type is being used, for example, conn_1_pppoe_8_35, the name used
in the example below. Notice the VPI and VCI values are included in the name. It is not functionally necessary
to change the name of the connection, this is done merely to provide descriptive reference.
Figure 3-6. Setup – Configure Connection 1 for PPPoE

UPnP
UPnP supports zero-configuration networking and automatic discovery for many types of networked devices.
When enabled, it allows other devices that support UPnP to dynamically join a network, obtain an IP address,
convey its capabilities, and learn about the presence and capabilities of other devices. DHCP and DNS service
can also be used if available on the network. UPnP also allows supported devices to leave a network
automatically without adverse effects to the device or other devices on the network.
UPnP can be supported by diverse networking media including Ethernet, 802.11b wireless, Firewire, phoneline
and powerline networking.

hyperlink in the Advanced setup menu. You can also click on the New IP button located in the Port Forwarding,
Access Control and Advanced Security menus to access this menu. In order to use these advanced features it is
necessary to have IP addresses available for configuration. If there are no IP addresses listed in the LAN Clients
menu, it will not be possible to configure Port Forwarding, Access Control and Advanced Security.
Use the LAN Clients menus to add or delete static IP addresses for the advanced functions mentioned above, or
to Reserve a Dynamically assigned IP address for an advanced function. Dynamically assigned IP addresses will
only be listed if DHCP is enabled on the Router.
Figure 4-3. LAN Clients Setup
To add a static IP address to the list of available IP addresses, type an IP address that falls within the range a
available IP addresses and click on the Add button. In the example above, available addresses range from
10.0.0.1 to 10.255.255.254. Any addresses added will appear in the list of Static Addresses available for
advanced configuration. These addresses can then be used in the other Port Forwarding, Access Control and
Advanced Security menus.
To delete an IP address from the list of Static Addresses, click the Delete box for the address or addresses you
want to eliminate and click on the Apply button.
Dynamically assigned IP addresses may be reserved so that the LAN IP address for the device does not expire.
This will create a permanent entry for the device in the ARP table and in effect, it becomes a static IP address.
Click to check the Reserve box for the address or addresses you want to reserve and click the Apply button.

specific UDP or TCP ports. Access control operates for specific IP addresses across all WAN connections. If
you are using more than one WAN connection, a single set of access rules is maintained for each controlled IP
address that operates on all WAN connections.
Note
In order to use Port Access Control, Firewall support must be enabled. See
Enable/Disable NAT and Firewall in the Advanced Security menu.

Multiple Virtual Connections
The Router can use up to eight simultaneous PVC connections. These additional connections occupy the same
bandwidth used for ADSL service. Additional PVC connections can be added to establish a private connection to
remote offices or maintain a server accessible through the WAN port. Provision for additional PVC profiles must
be done through the telephone company or telecommunications services company. The remote user must have
suitable ADSL equipment for a successful connection.
The New Connection menu is used to configure additional WAN connection that can operate simultaneously
with the other connections. PPPoE type WAN connections can be disconnected or connected as needed. NonPPPoE type connections must be deleted from the configuration settings if you want to disable them.
To set up additional virtual connections, follow the procedure described in Create a New Connection. Keep in
mind that each new connection must have a VPI/VCI value set that is unique to the Router. The numbers for
these values will be provided by your service provider.
PPPoE and PPPoA connections may be connected and disconnected with the Connect and Disconnect menu
buttons located in the connection settings menu.
The remaining connection types (Bridge, Static, DHCP and CLIP) connect upon saving the settings and
restarting the Router. These connections can be disconnected only if the connection set is deleted. To delete any
WAN connection set, click on the Delete button in the menu for the connection.

IP Address Setup
The DSL-502T is designed to provide network administrators maximum flexibility for IP addressing on the
Ethernet LAN. The easiest IP setup choice in most cases is to let the Router do it using DHCP, which is enabled
by default. This appendix briefly describes various options including DHCP, used for IP setup on a LAN. If you
are new to IP networking, the next appendix provides some background information on basic IP concepts.
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 is shipped with a preset default IP address setting of 192.168.1.1 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
Manually configuring IP settings for the LAN means you must manually set an IP address, subnet mask and IP
address of the default gateway (the Router’s IP address) on each networked computer. The example listed below
describes IP configuration for computers running Windows 95 or Windows 98. Regardless of what operating
system is used on each workstation, the three network IP settings must be defined so the network interface used
by each workstation can be identified by the Router, and vice versa. For detailed information about configuring
your workstations IP settings, consult the user’s guide included with the operating system or the network
interface card (NIC).
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.

IP Setup - Example #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. 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
63
DSL-502T ADSL Router User’s Guide
address (each computer must have a unique address to distinguish it on the network). The IP address scheme
used in Example #1 can be used for any LAN that requires up to 253 separate IP addresses (excluding the
Router). Notice 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 settings for
workstation 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
When planning your LAN IP address setup, you may use any scheme allowed by rules that govern IP
assignment. It may be more convenient or easier to remember an IP scheme that use a different address for the
Router. Or you may be installing the Router on a network that has already established the IP settings. Changing
the IP address is a simple matter and can be done using the web manager. If you are incorporating the Router
into a LAN with an existing IP structure, be sure to disable the DHCP function. Also, consider the effects of the
NAT function - which is enable by default.
An IP addressing scheme commonly used for Ethernet LANs establishes 10.0.0.1 as the base address for the
network. Using Example #2 below, the Router is assigned the base address 10.0.0.1 and the remaining addresses
are assigned manually or using DHCP.

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 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.
65
DSL-502T 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.
IP Network Classes

65,534
C
2,097,150
192.0.1(.0) to 223.255.254(.0)
254
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 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
10.0.0.0
10.255.255.255
B
172.16.0.0
172.31.255.255
C
192.168.0.0
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

Subnet Mask
In the absence of subnetworks, standard TCP/IP addressing may be used by specifying subnet masks as shown
below.
IP Class
Subnet Mask
Class A
255.0.0.0
Class B
255.255.0.0
Class C
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.

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 telephone 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.
Microfilters
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
Important: 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 RJ-11 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.
