DSL-G604T Wireless A DSL Router User’s Guide

About This User’s Guide

This user’s guide provides instructions on how to install the DSL-G604T Wireless ADSL Router and use it to provide Internet access for an Ethernet or 802.11g/802.11b wireless LAN.

If you are using a computer with a functioning Ethernet port, the quickest and easiest way to set up the DSL-G604T is to insert the Installation CD into the CD-ROM drive of your computer and follow the instructions

provided in the Quick Installation Guide.

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, connect the cables 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 service and wireless LAN.

The Setup Wizard

Many users will be able to configure all the settings necessary to use the DSL-G604T with the Setup Wizard. For ADSL connections that use Dynamic, Statis IP, PPPoE/PPPoA, or Bridge connections, the simplest way to setup the DSL-G604T is to use the Setup Wizard to configure the Internet connection. Once you access the web interface used to configure the device, just launch the Setup Wizard to configure your Internet connection. Once you have the Internet connection established, set up the wireless nework and security settings using web manager.

DSL-G604T Wireless A DSL Router User’s Guide

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 most 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 section labeled “Information you will need from your ADSL service provider” 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-G604T 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.

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 laptop 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.

Wireless LAN Configuration

Wireless LAN settings for 802.11g and 802.11b wireless operation must be enabled using the Setup Wizard before it can be configured. Basic wireless settings including the Channel and SSID can be configured through the Setup Wizard. Advanced wireless security settings can also be configured with the Setup Wizard.

Security for wireless communication can be accomplished in a number of ways. The DSL-G604T supports WEP, WPA and WPA -PSK.

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.

This is the method your ADSL service provider uses to transport data betw een the Internet and your computer. Most users will use the default PPPoE/PPPoA, connection type. The Setup Wizard can be used to configure a PPPoE/PPPoA connection type. You may need to specify one of the following connection types (PPPoE LLC, PPPoA LLC or PPPoA VC-MUX). The other available connection and encapsulation combinations must be configured using the web manager. These include Bridge Mode (1483 Bridged IP LLC or 1483 Bridged IP VC-MUX), and Static IP (Bridged IP LLC, 1483 Bridged IP VC-MUX, 1483 Routed IP LLC, 1483 Routed IP VC-MUX or IPoA ).

Most users will not be required to cha n ge this set t i ng. Th e Virtual Path Identifier (VPI) is used in conjunction with the Virtual Channel Identifier (VCI) to identify the data path between your ADSL service provider’s network and your computer. If you are setting up the Router for multiple virtua l connections, you will need to configure the VPI and VCI as instructed by your ADSL service provider for the additional connections. This setting can be changed in the WAN menu of the web management interface.

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-G604T Router is designed to provide a simple and cost-effective ADSL Internet connection for a private Ethernet or 802.11g/802.11b wireless network. The Router combines high-speed ADSL Internet connection, IP routing for the LAN and wireless connectivity in one package.

The Router is easy to install and use. The DSL-G604T connects to an Ethernet LAN or computers via standard Ethernet ports. The ADSL connection is made using ordinary telephone line with standard connectors. Multiple workstations can be networked and connected to the Internet using a single Wide Area Network (WAN) interface and single global IP address. 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.

Network and Router management is done through the web-based management interface that can be accessed through the local Ethernet using any web browser. You may also enable remote management to enable configuration of the Router via the WAN interface.

ADSL

Asymmetric Digital Subscriber Line (ADSL) is a broadband network technology that utilizes standard twistedpair copper wire telephone lines to enable broadband high-speed digital data transmission and bandwidth hungry applications for business and residential customers.

ADSL routers and modems provide faster downloads and more reliable connectivity to the user without loss of quality or disruption of voice/fax telephone capabilities.

ADSL service operates at speeds of up to 8 Mbps downstream and up to 640 Kbps upstream. A secure dedicated point-to-point connection is established between the user and the central office of the service provider.

802.11g Wireless

The embedded 802.11g wireless access point provides Internet access and connectivity to the Ethernet for

802.11g and 802.11b wireless workstations. IEEE 802.11g is fully compatible with IEEE 802.11b wireless devices. The 802.11g standard supports data transfer rates of up to 54 Mbps.* The Router’s wireless access point supports common security protocols used for wireless LAN including WEP encryption, 802.1x and WPA.

*Maximum wireless signal rate based on IEEE Standard 802.11g specifications. Actual data throughput will vary. Network conditions and environmental factors, including volume of network traffic, building materials and construction, and network overhead lower actual data throughput rate.

Router Features

The DSL-G604T Wireless ADSL Router utilizes the latest ADSL enhancements to provide a reliable Internet portal suitable for most small to medium sized offices. DSL-G604T advantages include:

• 802.11g Wireless Access Point – The built-in 802.11g wireless access point connects 802.11g and 802.11b

wireless devices to the Internet and the Ethernet.

• PPP (Point-to-Point Protocol) Security – The DSL-G604T 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-G604T 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-G604T 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-G604T supports both RIP-1 and RIP-2 exchanges with other routers. Using both

versions allow 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 –

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-G604T 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 standard.

• Full Network Management – The DSL-G604T incorporates SNMP (Simple Network Management

Protocol) support for web-based management and text-based network management via Telnet connection.

•

Telnet Connection –

remotely.

• Easy Installation – The DSL-G604T 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.

This allows you to choose a default path for incoming data packets for which the

The Telnet enables a network manager to access the Router’s management software

Wireless LAN Basics

Some basic understanding of 802.11b/g wireless technology and terminology is useful when you are setting up the Router or any wireless access point. If you are not familiar with wireless networks please take a few minutes to learn the basics.

Radio Transmission

Wireless LAN or WLAN devices use electromagnetic waves within a broad, unlicensed range of the radio spectrum to transmit and receive radio signals. When a wireless access point is present, it becomes a base station for the WLAN nodes in its broadcast range. WLAN nodes transmit digital data using FM (frequency modulation) radio signals. WLAN devices generate a carrier wave and modulate this signal using various techniques. Digital data is superimposed onto the carrier signal. This radio signal carries data to WLAN devices within range of the transmitting device. The antennae of WLAN devices listen for and receive the signal. The signal is demodulated and the transmitted data extracted. The transmission method used by the access point is called Direct Sequence Spread Spectrum (DSSS) and operates in a range of the radio spectrum between 2.4GHz

and 2.5GHz for transmission. See the technical specifications for more details on wireless operation.

Range

Range should not be a problem in most homes or small offices. If you experience low or no signal strength in some areas, consider positioning the Router in a location between the WLAN devices that maintains a roughly equal straight-line distance to all devices that need to access the Router through the wireless interface. Adding more 802.11g access points to rooms where the signal is weak can improve signal strength. Read the section about placement of the Router titled Location in the next chapter, Hardware Installation, for more information.

SSID

Wireless networks use an SSID (Service Set Identifier) to allow wireless devices to roam within the range of the network. Wireless devices that wish to communicate with each other must use the same SSID. Several access points can be set up using the same SSID so that wireless stations can move from one location to another without losing connection to the wireless network.

The DSL-G604T operates in Infrastructure mode. It controls network access on the wireless interface in its broadcast area. It will allow access to the wireless network to devices using the correct SSID after a negotiation process takes place. By default he DSL-G604T broadcasts its SSID so that any wireless station in range can learn the SSID and ask permission to associate with it. Many wireless adapters are able to survey or scan the wireless environment for access points. An access point in Infrastructure mode allows wireless devices to survey that network and select an access point with which to associate. You may disable SSID broadcasting in the web manager’s wireless menu.

Wireless Security

Various security options are available on the DSL-G604T including open or WEP, WPA, and WPA-PSK. Authentication may use an open system or a shared key. For details on these methods and how to use them, please read the wireless LAN configuration information in chapters 3 (Basic Router Configuration) and 4 (Advanced Router Configuration).

About 802.11g Wireless

Today's 11-megabits-per-second 802.11b wireless networks are fine for broadband Internet access (which typically tops out at about 1 mbps) but rather slow for large internal file transfers or streaming video. However, 54-mbps, corporate-oriented 802.11a is expensive--and because its radio uses the 5-GHz band and 802.11b uses the 2.4-GHz band, upgrading to an 802.11a network means either scrapping 802.11b gear or buying even-pricier hardware that can support both standards.

But 802.11g promises the same speed as 802.11a and the ability to coexist with 802.11b equipment on one network, since it too uses the 2.4-GHz band.

802.11g is an extension to 802.11b, the basis of many wireless LANs in existence today. 802.11g will broaden

802.11b's data rates to 54 Mbps* within the 2.4 GHz band using OFDM (orthogonal frequency division multiplexing) technology. Because of backward compatibility, an 802.11b radio card will interface directly with an 802.11g access point (and vice versa) at 11 Mbps or lower depending on range. You should be able to upgrade the newer 802.11b access points to be 802.11g compliant via relatively easy firmware upgrades.

Similar to 802.11b, 802.11g operates in the 2.4GHz band, and the transmitted signal uses approximately 30MHz, which is one third of the band. This limits the number of non-overlapping 802.11g access points to three, which is the same as 802.11b.

Hardware Installation

The DSL-G604T maintains three separate interfaces, an Ethernet LAN, a wireless LAN and an ADSL (WAN) 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.

Choosing the Best Location for Wireless Operation

Many environmental factors can affect the effective wireless function of the DSL-G604T. If this is your first time setting up a wireless network device, read and consider the points listed below.

The access point 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.

Designed to go up to 100 meters indoors and up to 300 meters outdoors, Wireless LAN lets you access your network from anywhere you want. However, the number of walls, ceilings, or other objects that the wireless signals must pass through can limit signal range. Typical ranges vary depending on the types of materials and background RF noise in your home or business. For optimum range and signal strength, use these basic

guidelines:

1. Keep the number of walls and ceilings to a minimum:

The signal emitted from Wireless LAN devices can penetrate through ceilings and walls. However, each

wall or ceiling can reduce the range of Wireless LAN devices from 1 to 30M. Position your wireless

devices so that the number of walls or ceilings obstructing the signal path is minimized.

2. Consider the direct line between access points and workstations: A wall that is 0.5 meters thick, at a

45-degree angle appears to be almost 1 meter thick. At a 2-degree angle, it is over 14 meters thick. Be

careful to position access points and client adapters so the signal can travel straight through (90º angle)

a wall or ceiling for better reception.

3. Building Materials make a difference: Buildings constructed using metal framing or doors can reduce

effective range of the device. If possible, position wireless devices so that their signal can pass through

drywall or open doorways, avoid positioning them so that their signal must pass through metallic

materials. Poured concrete walls are reinforced with steel while cinderblock walls generally have little

or no structural steel.

4. Position the antenna for best reception. Play around with the antenna position to see if signal strength

improves. Some adapters or access points allow the user to judge the strength of the signal.

Keep your product away (at least 1-2 meters) from electrical devices:

Position wireless devices away from electrical devices that generate RF noise such as microwave ovens,

monitors, electric motors, etc.

Power on Router

CAUTION:

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.

The Router must be used with the power adapter included with the device.

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 device settings will be restored to the factory default IP address 192.168.1.1 and the subnet mask is

255.0.0.0, the default management Username is admin and the default Password is admin.

Wired Network Connections

Wired network connections are provided through the ADSL port and the four Ethernet ports on the back of the Router. See the Rear Panel diagram above and the illustrations below for examples.

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 10/100 BASE-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 between 0~100Mbps, 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 o hub for another device, connect to any on the othe 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 as shown in this diagram.

The illustration below shows the DSL-G604T connected to Ethernet LAN devices, Wireless LAN devices and the Internet.

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.

Configure the WAN Connection

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.

Once your are able to access the configuration software you can

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.

If you are using this Router to provide Internet access for more than one compu ter, you

Note

can use these instructions later to change the IP settings for the other comp uters. 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 Windows XP for DHCP

Use the following steps to configure a computer running Windows XP to be a DHCP client.

1. From the Start menu on your desktop, go to Settings, then click on Network Connections.

ecomes the default gateway fo DHCP client connected to it. Keep in mind that if you change the IP address of the Router, yo must change the range of IP addresses in the pool used fo DHCP on the LAN.

To display the DHCP Serve menu, click the DHCP button in the Home directory. Active

DHCP Clients appear listed in

the DHCP Client List below the

configuration menu. Informatio about DHCP clients includes the IP address, MAC address, hos name and lease time are displayed in the list.

Configure DHCP server settings for the LAN

The three options for DHCP service are as follows:

 You may use the Router as a DHCP server for your LAN.

 You can disable DHCP service and manually configure IP settings for workstations.

 You use DHCP service provided by your ISP.

Follow the instructions below according to which of the above DHCP options you want to use. When you have

configured the DHCP Settings as you want them, click the Apply button to commit the new settings. The new DHCP settings must be saved and the Router must be restarted for the settings to go into effect. To Save & Reboot the Router, click on the Tools directory tab and then click the Admin menu button. In the Administrator Settings menu, click he Save & Reboot button.

Use the Router for DHCP

To use the built-in DHCP server, click to select the DHCP Server option if it is 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. The Ending IP Address is the highest IP address number in the pool. 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.

Disable the DHCP Server

To disable DHCP, click to select the No DHCP option and click on the Apply button.

DHCP Relay

To use DHCP service from your ISP, select the DHCP Relay option and type the DHCP Relay IP address in the space provided. Click Apply to begin DHCP relay from the ISP.

DNS Server Settings

The Router can be configured to relay DNS from your ISP or another available service to workstations on your LAN. When using DNS relay, the Router will accept DNS requests from hosts on the LAN and forward them to the ISP (or alternative) DNS servers. DNS relay can use auto discovery or the DNS IP address can be manually entered by the user. Alternatively, you may also disable the DNS relay and configure hosts on your LAN to use DNS servers directly. Most users who are using the Router for DHCP service on the LAN and are using DNS servers on the ISP’s network. Leave DNS relay enabled (either auto discovery of user configured), unless specified by your ISP.

Configure DNS Settings

In the DNS Relay Selection pull-down menu, choose to Use Auto Discovery, Use User Configu red or Disable DNS relay.

If you have not been given specific DNS server IP addresses or if the Router is not pre-configured with DNS server information, select the Auto Discover option for DNS relay. Auto discovery DNS instructs the Router to automatically obtain the DNS IP address from the ISP through DHCP. If your WAN connection uses a Static IP address, auto discovery for DNS cannot be used.

If you have DNS IP addresses provided by your ISP, enter these IP addresses in the available entry fields for the

Preferred DNS Server and the Alternative DNS Server.

If you choose to disable DNS relay, it will be necessary to configure DNS settings for hosts on the LAN since they will not be depending on the Router to forward the DNS requests.

When you have configured the DNS settings as desired, click the Apply button.

Click the Status tab to view the Device Information, Event Log, Traffic Statistics and ADSL Status information windows.

The Help menu presents links to pages that explain various functions and services provided by the Router.

Port Forwarding

Use the Port Forwarding menu to create Virtual Server functions through the Router. A Virtual Server can allow remote users to access services on your LAN such as FTP for file transfers or SMTP and POP3 for e-mail. The DSL-G604T will accept remote requests for these services at your Global IP Address, using the specified TCP or UDP protocol and port number, and then redirect these requests to the server on your LAN with the Private IP address you specify. Remember that the Private IP Address must be within the range specified for your LAN.

The Virtual Server feature employs UDP/TCP port redirection to direct traffic through the WAN port to specified servers on your private network. Port redirection can also be used to direct potentially hazardous packets to a proxy server outside your firewall. For example, you can configure the Router to direct HTTP packets to a designated HTTP server in the DMZ. You can define a set of instructions for a specific incoming port or for a range of incoming ports. Each instruction set or rule is indexed and can be modified or deleted later as needed.

Virtual server configuration sets can be used together with complimentary features such as Firewall Rules, DMZ devices and IP Filters to improve efficiency and security. Consider how these other functions will effect the virtual server sets you have configured and enabled.

The table below describes the configuration settings presented in the Virtual Server menu.

Figure 4- 1. Virtual Server Menu and List

To modify virtual server settings for any previously created virtual server set listed, click on the note pad icon in

the right hand column of the Virtual Servers List for the set you want to configure. The set will appear

highlighted in the list and the parameters that have been configured appear in the settings fields above the list.

Adjust the settings as desired and click the Apply button to put them into effect.

To configure a virtual server set, define the following settings in the Virtual Server configuration menu located in the top half of the browser window.

options from the pull-down menu to define a TCP, UDP or Both. The choice of this protocol is dependent on the application that is providing the service. If you do not know which protocol to choose, check your application’s documentation.

Configure a range of ports for forwarding. Type the lowest numbered port in the range in the Port Start space. Type the highest numbered port in the Port

Port Start/Port End

End space. For a single port, just enter the same number in both spaces. Virtual server port redirection must be used with a specified ser ver or

computer on the LAN (identified by the Private IP address). This is the local port being forwarded to from the Port Start/Port End port(s).

Port Map

Keep in mind that if you use a non-standard port number for an application with a reserved UDP/TCP port, some additional configuration may be required for the servers or workstations using the application on the LAN side.

Click the Apply button to put the new virtual server configuration set or modification into effect. Any server sets

configured in the menu will appear in the Virtual Server List with the new settings. The Router must save the new settings and reboot before the new virtual server configurations are applied.

To remove any configuration set from the Virtual Server List, click on the trashcan icon for set you want to delete.

Some applications require multiple TCP or UDP ports to function properly. Applications such as Internet gaming, video conferencing, and Internet telephony

Note

are some examples of applications that often require multiple connections. These applications often conflict with NAT, and therefore require special handling. See the discussion of DMZ configuration below.

Filters

Filter rules in the Router are put in place to allow or block specified traffic. The Filter Rules however can be used in a single direction to examine and then Allow or Deny traffic for Inbound (WAN to LAN) or Outbound (LAN to WAN) routed data. The rules based on IP address and TCP/UDP port.

Configure the filter rules as desired and click the Apply button to create the rule. The newly created rule appears

listed in the Outbound Filter List at the bottom of the menu. The table below describes the various parameters that are configured for the filter rules.

Figure 4- 2. Filters Configuration Menu

To modify any previously created filter rule, click on the note pad icon in the right hand column of the Filter List

Filters List with the new settings. The Router must save the new settings and reboot before the new rules are applied.

DMZ

Since some applications are not compatible with NAT, the Router supports use of a DMZ IP address for a single host on the LAN. This IP address is not protected by NAT and will therefore be visible to agents on the Internet with the right type of software. Keep in mind that any client PC in the DMZ will be exposed to various types of security risks. If you use the DMZ, take measures (such as client-based virus protection) to protect the remaining client PCs on your LAN from possible contamination through the DMZ.

To designate a DMZ IP address, type in the IP Address of the server or device on your LAN, select the Enabled radio button and click the Apply button. To remove DMZ status from the designated IP address, select the

Disabled radio button and click Apply. It will be necessary to save the settings and reboot the Router before the DMZ is activated.

Firewall

The Firewall Configuration men allows the Router to enforce specific predefined policies intended to protect against certain common types of attacks. There are two general types o

rotection (DoS and Port Scan) that can be enabled on the Router, as well as filtering for specific

acket types sometimes used b hackers.

You can choose to Enable o Disable protection against

customized basket of attack an

scan types. To enable DoS

Protection or Port Scan Protection, select the Enable

radio button for the protection type and click in the selection

oxes for the various types o

rotection listed under each.

Figure 4- 4. Firewall Configuration Menu

When DoS, Port Scan, or Service Filtering Protection is enabled, it will create a firewall policy to protect your network against the following:

Dos Protection Port Scan Protection Service Filtering

SYN Flood check ICMP Redirection check

Nmap/FIN attack URG/PSH attack Xmas Tree Scan Null Scan attack SYN/RST attack SYN/FIN Scan

Ping from WAN Telnet from WAN FTP from WAN DNS from WAN IKE from WAN RIP from WAN DHCP from WAN

A DoS "denial-of-service" attack is characterized by an explicit attempt by attackers to prevent legitimate users of a service from using that service. Examples include: attempts to "flood" a network, thereby preventing legitimate network traffic, attempts to disrupt connections between two machines, thereby preventing access to a service, attempts to prevent a particular individual from accessing a service, or, attempts to disrupt service to a specific system or person.

Port scan protection is designed to block attempts to discover vulnerable ports or services that might be exploited in an attack from the WAN.

The Service Filtering options allow you to block FTP, Telnet response, Pings, etc, from the external network. Check the category you want to block to enable filtering of that type of packet.

When you have selected the desired Firewall policies, click the Apply button to enforce the policies. Remember

to save any configuration changes.

Static Routing

Use Static Routing to specify a route used for data traffic within your Ethernet LAN or to route data on the WAN. This is used to specify that all packets destined for a particular network or subnet use a predetermined gateway.

Multiple Virtual Connections

The Router supports multiple virtual connections. Up to eight PVCs to eight separate destinations can be created and operated simultaneously utilizing the same bandwidth. Additional PVC connections can be added for various purposes. For example, you may want to establish a private connection to remote office in order to create an extended LAN, or setup a server on a separate connection. Provisioning for additional PVC profiles must be done through your telecommunications services provider. Extended LAN operations employing multiple virtual connections require ADSL routers or modems at the remote site for a successful connection. Contact your ISP or telecommunications service provider if you are interested in setting up multiple virtual connections.

After the necessary arrangements have been made to use the Router with multiple virtual connections, follow the instructions below to setup the Router using the VPI/VCI settings given to you by your server provider.

Configure Multiple PVCs

Additional PVCs can be configured by first accessing the WAN configuration menu in the Home directory.

IP Address Setup

The DSL-G604T 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

4. Choose the Specify an IP address option and edit the address settings accordingly. Consult the table below

component and click Properties.

IP Setup - Example #1

Please note that when using the default IP address as in the above example, the first number in the IP address must always be the same with only the second, third and fourth number changing. The first number defines the network IP address (all machines must belong to the same IP network), while the last three numbers denote the

host IP 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 computer’s 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 3 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 (see LAN IP Address in Chapter 5). 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 NAT (Network Address Translation). This is enabled by default but may be disabled in the NAT menu of the Advanced directory.

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.

These two examples are only examples you can use to help you get started. Other common private network IP addressing schemes use a base address of 192.168.1.1 or 192.168.0.1. If you are interested in more advanced information on how to use IP addressing on a LAN there are numerous resources freely available on the Internet. There are also many books and chapters of books on the subject of IP address assignment, IP networking and the TCP/IP protocol suite.

IP Concepts

This appendix describes some basic IP concepts, the TCP/IP addressing scheme and shows 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.

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

16,382 128.1(.0.0) to 191.254(.0.0) 65,534

B C

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 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 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 Router to the ADSL line.

Microfilters

Unless you are instructed to use a “line splitter” (see below), it is optional to install a microfilter (low pass filter) device for each telephone or telephone device (answering machines, Faxes etc.) that shares 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 Router 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 Router 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 Router 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 Router. Phone – This port connects to a telephone or other telephone device.

The diagram below illustrates the proper use of the splitter.
