Features
• PPP (Point-to-Point Protocol) Security – The DSL-2640R ADSL Router supports PAP (Password Authentication Protocol) and CHAP
(Challenge Handshake Authentication Protocol) for PPP connections. The Router also supports MSCHAP.
• DHCP Support – Dynamic Host Configuration Protocol automatically and dynamically assigns all 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-2640R 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 (T ransfer C ontrol Protocol/Internet Protocol) – The DSL-2640R 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-2640R 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 an 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.
• Precise ATM Traffic Shaping – Traf fic 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.
• Full Network Management – The DSL-2640R incorporates SNMP (Simple Network Management Protocol) support for web-based
management and text-based network management.
• Easy Installation – The DSL-2640R 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.

Section 2 – Installation
Installation
This section will walk you through the installation process. Placement of the Wireless ADSL Router is very important. Do not place the Router in an
enclosed area such as a closet, cabinet, or in the attic or garage. Place the Wireless ADSL Router in a location where it can be easily connected to
Ethernet devices, the telephone line as well as to a power source.
Before You Begin
Please read and make sure you understand all the prerequisites for proper ins tallation of your new Router. Have all the necessary information and
equipment on hand before beginning the installation.
Installation Notes
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 Passwo rd) is required. For others, various parameters that control and define the Inte rnet
connection will be required. You can print out the two pages below and use the tables to l ist thi s informatio n. Th is way yo u have a hard copy of all
the information needed to setup the Router. If it is necessary to reconfigure the d evice, all the necessary information can be easily accesse d. 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 passiv e 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-2640R 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, Windows XP, and Windows
Vista.
D-Link DSL-2640R User Manual 5
Section 2 – Installation
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 6.0, Netscape Navigator® version 6.2.3, 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 or PPPoA 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. Y our network service provider will give you instructions about any additional connection software or NIC
configuration that may be required.
Wireless LAN
Computers using the Wireless network can access the Internet or use the embedded 802.1g wireless access point. Wireless workstations must
have an 802.1g or 802.1b wireless network card installed to use the Wireless ADSL Router. In addition the workstations must be configured to
operate on the same channel and SSID as the Wireless ADSL Router. If wireless security is used, the wireless workstations must be properly
configured for the security settings used.

Network Connections
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 ADS L port
(RJ-1 1 recept acle) 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. 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.
Computer to Router Connection
You can connect the Router directly to a 10/100BASE-TX Ethernet adapter card (NIC) installed on a PC using the Ethernet cable provided.
Wireless Connection to Router
The Router’s embedded 802.11g wireless access point should be configured to suit the local wireless network. All 802.11g or 802.11b devices that
associate with the Router’s wireless access point must have the same SSID and channel. If wireless security is used, the wireless clients must be
configured with the correct security inf ormation t o use the R outer. More information on config uring t he w ireless sett ings is found later in this manual.

If your account is time-based, that is, if your connection fees are based
on the amount of time the Router is actively connected to the Internet,
select the Connect On-Demand option and enter an appropriate idle
timeout in the entry field provided. If your account is billed with a flat fee
regardless of how much time the Router is connected, select the Always
On option. This will maintain the PPP session as long as the Router is
powered on.
8. The TCP MSS option can be used when excessive fragmentation of
packets effect download speeds. Enter a value for the Maximum
Segment Size to avoid fragmenting TCP packets
9. Typically the globally IP settings (i.e. IP address for the WAN interface)
for a PPPoA or PPPoA connection will use Dynamic IP assignment from
the ISP. Some accounts may be assigned a specific global IP address. If
you have been give an IP address for you PPPoE/PPPoA connection,
select the Static option from the Get IP Address pull-down menu and
enter the Static IP Address, IP Subnet M ask, and Gateway information.
10. NAT should remain Enabled. If you disable NAT, you will not be able to
use more than one computer for Internet connections. NAT is Enabled
and Disabled system-wide, therefore if you are using multiple virtual
connections, NAT will disabled on all connections.
11. Turn on the Default Route feature if you want to use the Router as the
default route to the Internet for your LAN. Whenever a computer on the
LAN attempts to access the Internet, the Router becomes the Internet
gateway to the computer. If you have an alternative route for Internet
traffic you may turn this off without effecting the Router’s connection.
12. Leave the TCP MTU Option value at the default setting unless you have
specific reasons to change this.
13. Select the desired Dynamic Route from RIP1, RIP2-B, or RIP2-M. Next,
set the Direction to Both, IN Only, OUT Only, or None.
14. The Multicast feature is Disabled by default. Toggle between IGMP v1
and IGMP v2.
15. When you are satisfied that all the Internet settings are configured
correctly, click on the SAVE button.
When PPPoE or PPPoA is used, the Router becomes the PPP client, that is, all the
software needed to est ab lish and maintain the connection is located on the Router.
ISPs frequently require PPP client software to be installed on workstations. If any
computers have PPP client software installed on them, this software must be
removed or at least disabled before the computers are able to connect to the
Internet through the Router. If you are required to provide a User Name and
Password every time you access the Internet, your computer may have PPP client
software installed on it.

A Dynamic IP Address connection configures the Router to automatically obtain its
global IP address from a DHCP server on the ISP’s network. The service provider
assigns a global IP address from a pool of addresses available to the service
provider. Typically the IP address assigned has a long lease time, so it will likely be
the same address each time the Router requests an IP address.

LAN Setup
To access the LAN window, click the LAN button in the Interface Setup directory.
You can configure the LAN IP address to suit your preference. Many users
will find it convenient to use the default settings together with DHCP
service to manage the IP settings for their private network. The IP address
of the Router is the base address used for DHCP. In order to use the
Router for DHCP on your LAN, the IP address pool used for DHCP must
be compatible with the IP address of the Router. The IP addresses
available in the DHCP IP address pool will change automatically if you
change the IP address of the Router.
To configure the LAN IP address, type in the desired values and click the
SAVE button. Your web browser should automatically be redirected to the
new IP address. You will b e asked to login to the Router’s web manager
again.
The DHCP server is enabled by default for the Router’s Ethernet LAN
interface. DHCP service will supply IP settings to workstations configured
to automatically obtain IP s ettings that a re connect ed to the Route r though
the Ethernet port. When the Router is used for DHCP it becomes the
default gateway for DHCP client connected to it. Keep in mind that if you
change the IP address of the Router the ra nge of IP ad dresse s in the poo l
used for DHCP on the LAN will also be changed. The IP address pool can
be up to 253 IP addresses.
The three options for DHCP service are as follows:
Use the Router as a DHCP server for your LAN.
Disable DHCP service an d manually configure IP settings for
workstations.
Use DHCP service provided by your ISP.
D-Link DSL-2640R User Manual 25
Section 3 – Configuration
Use the Router for DHCP
To use the built-in DHCP server , click t he DHCP radio button to Enabled if it has not already selected. The IP Address Pool settings can be adjusted.
The Starting IP Address is the lowest available IP address (default = 192.168.1.2). If you change the IP address of the Router, this will change
automatically to be 1 more that the IP address of the Router. Type in the Lease Time in the entry field provided. This is the amount of time in
seconds that a workstation is allowed to reserve an IP address in the pool if the workstation is disconnected from the network or powered off.
You may also configure DNS settings for the LAN when using the Router in DHCP mode. Toggle the DNS Relay setting to Use User Discovered
DNS Server Only from Use Auto Discovered DNS Server Only and enter the IP addresses for the Primary DNS Server and Secondary DNS
Server in the field provided. The manually configured DNS settings will be supplied to clients that are configured to request them from the Router.
Disable the DHCP Server
To disable DHCP, select the Disabled option and click on the SAVE button. Choosing this option requires that workstations on the local network
must be configured manually or use another DHCP server to obtain IP settings.
If you configure IP settings manually, make sure to use IP addresses in the subnet of the Router. Y ou will need to use the Router’s IP address as the
Default Gateway for workstations in order to provide Internet access.
Use DHCP Relay
To use DHCP service from your ISP or another DHCP server, select the Relay option and type the DHCP Server IP for Relay Agent address in the
space provided. Click SA VE to begin DHCP relay from the ISP.
