DSL-504 ADSL Ethernet Router User’s Guide

About This User’s Guide

This user’s guide provides instructions on how to install the DSL-504 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, you can use the Quick Installation Guide to quickly establish your ADSL connection and access the Internet.

Guide Overview

Introduction – Describes the Router and its key features. Provides an introduction to ADSL. Lists standards to which the Router complies. Contains a packing list.

Hardware Installation – Discusses how to connect the Router to an Ethernet LAN. Configuring the Router for the First Time – Provides information on how to configure the Router and

establish the WAN connection using the web-based manager. Web-based Configuration – Describes how to use the web-based manager to change Router settings and

configure additional virtual connections (PVCs). Appendix A - Technical Specifications – Lists the technical specifications of the Router, including

standards compliance.

Appendix B - Low Pass Filters – Illustrated examples of how to use low pass filters.

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. Check the contents of the package to be certain that everything listed on the packing list is included. A packing list is included at the end of this section. The information you will need includes the account name or number and the password used

to gain access to your service provider’s network, and ultimately to the Internet. In addition, some users may be given information used to configure the Router so it can establish a connection to the service provider’s network and the Internet.

2. Install the hardware, that is, connect the Ethernet and telephone cables to the device to establish the

necessary network links to your computer and to the service provider’s network and connect the power adapter to power on the Router.

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. Without the correct IP settings your computer will not be able to communicate with the ddevice or access the software used to configure the Router. Without compatible IP settings on your computer, you will not be able to use a web browser to access the Internet.

4. Use the web-based management software to configure the device to suit the requirements of your ADSL

account as instructed by your service provider. Some users may not need to change any of the device settings that establish and maintain the network connection. It may only be necessary to supply the user name or number and the password used for your account. Other users may not be required to change anything in the Router but they may need to install software on a computer used to access the Internet. Follow the instructions of your service provider to find out what is required for your account.

DSL-504 ADSL Ethernet Router User’s Guide

Requirements

To install and use the Router you need a computer equipped with an Ethernet port (such as an Ethernet NIC) and a web browser. You may also need to use information given to you by your service provider. This information is

stored in the Router’ s memory and used to establish the network connection and confirm your identity. The information may be only your user name (or number) and password, or it may be information used to define your Connection Profile. The connection profile is used to instruct the Router how to communicate with the computers and other routers that are used to control access to the service provider’ s network and ultimately to the Internet. The connection profile is a logical construct that establishes a definite path used for communication and defines the rules or protocols used to initiate and maintain the communication path.

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. Appendix B provides illustrated examples of how to install two common styles of low pass filters.

Operating System

The DSL-504 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.

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 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. Normally, an Ethernet port will be TCP/IP enabled, this means that it is able to communicate with other computers on an IP network (such as the Internet). Make sure your computer has the TCP/IP protocol installed. If you have accessed the Internet with the computer before, it already has this installed.

Additional Software

It may be necessary to install software on your computer that enables it to access the Internet. Additional software must be installed if you are using what is called a “bridged” connection. For a bridged connection, the information needed to make and maintain the Internet connection is stored on your computer, not in the Router. This type of connection is similar to the arrangement used for analog dial-up Routers, but the connection speed is much faster. Various terms are to describe a bridged ADSL connection including the term “RFC 1483 Bridge” used in this guide. RFC 1484 is a technical standard used to define a bridged connection.

If your ADSL service is delivered through a PPP (Point to Point Protocol) connection, the information needed to establish and maintain the Internet connection is stored in the Router. In this case, it is not necessary to install software on your computer.

DSL-504 ADSL Ethernet Router User’s Guide

Account Information (User Name and Password)

Most users will need to supply a user name and password used to access the service provider’ s network (and ultimately, the Internet). This information is stored either in the Router’s memory or on your computer depending on the type of connection profile you use.

ACCOUNT INFORMATION

User Name:

About Bridged Ethernet Connections (RFC 1483)

Using this method, the DSL-504 acts as a transparent bridge, and is invisible to other devices on both the WAN (wide area network) and LAN (local area network) side of the bridge. It is “ invisible” in the sense that it does not have an IP address associated with it. Every device connected to the WAN must have an IP address to be “ seen” on the network. Devices that connect to the Internet have a “ global” IP address that is unique and is used to identify the device so that it can send and receive data.

All connections to the Internet require a global IP address. It is therefore necessary to provide some means of acquiring global IP settings for your account. 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 computer, a server or a firewall device. 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 IPoA Connections (RFC 1577)

IP over ATM connections may require global IP settings for the device. Your service provider will give you IP settings information if needed. Some IPoA connections function like peer-to-peer connections and therefore do not require IP settings on the WAN interface.

Packing List

Open the shipping carton and carefully remove all items. In addition to this User's Guide, ascertain that you have:

1. One DSL-504 ADSL Ethernet Router

2. One User’s Guide

3. One twisted-pair telephone cable used for ADSL connection

4. One straight-through Ethernet cable

5. One AC power adapter suitable for your electric service

Introduction

This section provides a brief description of the Router, its associated technologies and a list of Router features.

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. For ADSL services, it is not necessary expensive new cabling or condition the line in any way.

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.

Router Description and Operation

The DSL-504 ADSL Router is designed to provide a simple, cost-effective and secure ADSL Internet connection for your small- to medium-sized private network. The DSL-504 combines the benefits of high-speed ADSL connection technology and TCP/IP routing with a conventional Ethernet interface in one compact and convenient package. ADSL connection technology enables many interactive multi-media applications such as video conferencing and collaborative computing.

The Router is easy to install and use. The DSL-504 connects to an Ethernet LAN via a standard Ethernet 10BASE-T interface using RJ-45 connectors. The ADSL connection is made using ordinary twisted-pair telephone line with standard RJ-11 connectors. This arrangement means that several computers can be networked and connected to the Internet using a single WAN interface and IP address.

The Router supports transparent bridging and can be used for IP packet routing over the Internet. Cost saving features of the Router such as NAT (Network Address Translator) and DHCP (Dynamic Host Configuration Protocol) improve administration efficiency and improve security. The advanced security enhancements, packet filtering and port redirection, can help protect your network from potentially devastating intrusions by malicious agents from outside your network.

DSL-504 ADSL Router User’s Guide

Router Features

The DSL-504 ADSL Ethernet Router utilizes the latest ADSL enhancements to provide a reliable Internet portal suitable for most small to medium sized offices. DSL-504 advantages include:

• PPP (Point-to-Point Protocol) Security The DSL-504 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-504 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-504 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-504 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-504 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 8 Mbps downstream

bit rate using the G.dmt.

• Full Network Management The DSL-504 incorporates SNMP (Simple Network Management Protocol)

support for web-based management and text-based network management via an RS-232 or Telnet connection.

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

remotely.

• Easy Installation The DSL-504 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

When selecting the location for the Router, be sure to allow room to access the connections on the rear panel. You will want to place the Router so that you will be able to see the LED indicators on the front panel. Allow some space above the Router for ventilation and make sure it is not close to heat sources or appliances that produce a lot of heat to avoid problems from overheating. As with any electrical device, use common sense when choosing a location for the Router.

Connect ADSL Line

Use the twisted-pair ADSL cable (standard telephone cable) included with the Router to connect it to your telephone line. Plug one end of the cable into the ADSL port (RJ-11 receptacle) on the rear panel of the Router and insert the other end into the wall jack. The ADSL connection is the physical connection for the Router’ s

WAN interface. It links the Router to the network service provider’ s backbone infrastructure. This is the Router’ s link to the Internet.

After the Router is powered on it will undergo a negotiation process to establish the ADSL connection. During this negotiation the Status LED will light a steady green, after which it will blink. If the ADSL line is disconnected or the Router restarted, it will repeat this process. If you are required to change the PVC settings (VPI/VCI values), these will need to be changed before the Router can complete a connection to the service provider’ s network through the ADSL connection.

Connect Router to the Ethernet

The Router may be connected to any 10/100BASE-TX Ethernet LAN. 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 Category 5 or better twisted-pair Ethernet cable with RJ-45 connectors. The RJ-45 ports on the Router are crossed (MDI-X) ports.

The rules governing Ethernet cable lengths apply to the LAN to Router connection. Be sure that any cable connecting a computer or the Ethernet LAN to the Router does not exceed 100 meters.

Computer to Router Connection

You can connect the Router directly to a 10/100BASE-TX Ethernet adapter card (NIC) installed on a computer or an embedded Ethernet port on a notebook computer or PC using the Ethernet cable provided. The Ethernet cable that come with the Router is known as a straight-through cable. This type of cable is appropriate for connecting to a crossed (MDI-X) port, the kind of port used on common Ethernet adapters for PCs and notebook computers.

Switch to Router Connection

If the switch has an available uplink port (MDI-II) you may connect the Router to the uplink port with a straightthrough cable. If the switch has an uplink port and you wish to reserve this for another device, connect to any on the other MDI-X ports (1x, 2x, etc.) with a crossed cable. The easiest way to see if the Ethernet connection is valid is to observe the LED indicators (see Figure 2- 1) when the device is connected and powered on.

Sample Ethernet LAN with the DSL-504 Router

Power On Router

To power on the device:

1. Insert the AC Power Adapter cord into the power receptacle located on the rear panel (see Figure 2- 2) of the

Router and plug the adapter into a 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 you have the Router connected to your network you can look at the Ethernet Link/Act LED indicators to

make sure they have valid connections. The Router will attempt to establish the ADSL connection, if the ADSL line is connected and the connection is properly configured (see Chapter 4) this should light up after several seconds.

Configuring the Router for the First Time

The first time you setup the Router it is recommended that you configure the WAN connection using a single computer. If you will use the device for a private network, make sure that the Router is connected only to the single computer and not connected to the LAN. Check the Ethernet connection to the computer by observing the Ethernet Link/Act LED indicator for the connected port.

Once you have the WAN connection functioning properly you may continue to make changes to Router configuration including IP settings and DHCP setup. This chapter is concerned only with using a 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 instruction 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.

The first page that appears after you successfully login displays the menu you need to configure the Router so it can connect to the Internet. The Router/Bridge Configuration menu is used to configure the Router’s

Connection Profile. The remainder of this chapter describes how to configure or change the Connection Profile. The following chapter describes the numerous other functions that can be performed by the Router.

Router/Bridge Configuration

Page 26

DSL-504 ADSL Router User’s Guide

When the Router connects to the Internet, it must first access your service provider’ s network, that is, it must

communicate with computers and other routers owned by your service provider. These computers and routers then provide the link to the Internet. The Router must be configured to communicate with the systems that give it access to the larger network (WAN). There are different protocols used to make this communication possible. Both ends of the connection must agree on what protocol to use and how to set up the connection. This is what you will configure the Router to do, to agree with the service provider’ s equipment and negotiate the terms of the connection using a language or protocol that both sides understand.

Sometimes it is also necessary to configure settings that define the path used for the ADSL connection. So in addition to telling the Router what protocol it must use, you may also be asked change the PVC (Permanent Virtual Channel) settings. These settings are defined by two number the VPI (Virtual Path Indicator) and the VCI (Virtual Channel Indicator).

Your service provider will give the information needed if any changes to the Connection Profile are necessary. To configure the WAN connection, open the Router/Bridge Configuration menu and perform the steps listed

below. Some of the settings do not need to be changed when you first set up the device but can be changed later if you choose.

1 The default Connection Profile used for the Router is labeled AU_PPPoE, VPI=8, VCI=35, Router with

PPPoE. If you have not been instructed to change this, proceed to the next step. If you have been instructed to change the Connection profile, read the next section Changing the Connection Profile.

2 The default Encapsulation Method used for sending data packets, labeled LLC should already be selected.

If you are not instructed to change this continue to the next step. If you are instructed to change this, select the remaining alterative option labeled VC mux by clicking the empty option circle. A black dot appears in the option circle of the selected option.

3 Under PPPoE Login enter the Login User Name used for your network account. The user name and login

password, are used to authenticate the identity of the ADSL client and provide access to the service provider’ s network. This user name may also be a number assigned to your account. Often the user name take’ s a form similar to an email address, something like: 12345678@ISPnetwork.com.au The user name and login password can be any combination of up to 64 characters.

4 Enter the Login Password. 5 Enter the Login Password again in the Confirm Password field. 6 Leave the default Authentication protocol labeled chap selected in the drop-down menu. The alternative

protocol labeled pap, can be selected from the pull-down menu if required by the service provider. Do not change this unless instructed to do so.

7 Leave the Connect on Demand option as enabled in the pull-down menu. This will allow the Router to

establish a WAN connection upon restarting. You may change this later if you wish.

8 Leave Idle Time set to the default value 0. Again, you can change this later if you wish. If you pay for your

Internet access according to the amount of time spent online, you may want to change this.

9 Click on the OK button on the bottom of the window. A new message prompt appears asking if you want

to restart the Router.

10 Click OK to save a restart. The Router will connect automatically upon restarting.

Changing the Connection Profile

The default connection profile used by the Router is labeled AU_PPPoE, VPI=8, VCI=35, Router with PPPoE. If you are not instructed to change the connection profile, it is not necessary to change this setting. However, if you are instructed to change it you will need to first change the connection profile and restart the Router before the Router can be used to access the Internet. Follow the instructions below to change the connection profile using one of the available connection profile options. To view the option available click the Connection Profile drop-down menu. If the protocol and VCI/VPI combination needed for your account is not listed here, it will be necessary to create a new connection profile option. If it is necessary to define a new connection profile option, please read the section on Connection Profile Configuration in the next chapter.

Available Connection Profiles

To change the connection profile using the Bridge/Router Configuration menu, follow these steps:

1. In the Bridge/Router Configuration window, use the drop-down menu under Connection Profile to

select the alternative profile you have been instructed to use.

2. Click on the OK button on the bottom of the window. A new message prompt appears asking if you

want to restart the Router.

3. Click OK to save a restart.

4. Upon restarting the Router it will be necessary to make further configuration changes. The settings you

are required to configure depends on the type of connection you are using. Follow the guidelines below for the type of connection used for your connection profile.

Router with PPPoA Connections

If your connection profile is a Router with PPPoA (AU_PPPoA, NZ_PPPoA) type profile, you will go through the same procedure listed in the previous section. From the users viewpoint, there is no difference between a PPPoA connection and a PPPoE connection. Follow these steps to complete the WAN configuration:

1 The default Encapsulation Method used for sending data packets, labeled LLC should already be selected.

2 Under PPPoE Login enter the Login User Name used for your network account. The user name and login

password, are used to authenticate the identity of the ADSL client and provide access to the service

provider’ s network. This user name may also be a number assigned to your account. Often the user name take’ s a form similar to an email address, something like: 12345678@ISPnetwork.com.au The user name and login password can be any combination of up to 64 characters.

Router with IPoA Connections

The IP over ATM connection method uses a different method to connect to the WAN. Some IPoA connections operate in a way similar to peer-to-peer connections, and therefore do not require a global IP address for the WAN interface. Some networks using IPoA do require global IP settings. In this case the settings are assigned manually or by DHCP. The default configuration for IPoA is peer-to-peer connection, that is, global IP settings are not required.

Router with IPoA Configuration

Follow these steps to configure an IPoA connection: 1 Choose one of the following options:

 For peer-to-peer network connections, check the IP Unnumbered

not already selected.

 For DHCP service, check the DHCP client box to select it.  To assign the global IP settings manually, type in the IP Address, Subnet Mask and De

Bridge with RFC 1483 Connections

Upon restarting the device, it will serve as a bridge, and therefore it will not have any IP function on the WAN interface. Your network service provider will instruct you on what further steps are needed to establish the WAN connection. You may have to install software on your computer or you may be required to alter the IP settings on your computer.

You will notice that the configuration options have changed since this device is no longer acting as a router.

Bridge with RFC 1483 Configuration

The only configuration option available for RFC 1483 connections is the Encapsulation Method. Do not change this unless you are instructed to do so. To change the Encapsulation Method select the option and click the OK button. You will have to restart the device again for the change to take effect.

When the Bridged Connection has been properly configured and any required additional software as been installed on the computer or computers using the device, you should be able to access the Internet according to the instructions that came with the software.

DSL-504 ADSL Router User’s Guide

Web-based Management

The DSL-504 offers a web-based (HTML) graphical user interface allowing users to manage the Router from anywhere on the LAN using a standard browser. A web browser is used to communicate directly with the Router and make changes to the configuration or monitor status.

Accessing the Web Manager

In order to use the web-based management software it will be necessary to use a computer that occupies the same subnet as the Router. The simplest way to do this for many users will be to use DHCP server that is enabled by default on the Router. Chapter 3 provides instructions on how to configure a system running Windows operating systems to be DHCP client. You may also specify IP settings for your computer. The Router has a default IP address of 192.168.0.1 and a subnet mask of 255.255.255.0. Once you have accessed the

configuration software you can configure the Router’ s IP settings and DHCP server configuration to suit your preferences.

To use the web-based management software run the browser you have installed on your computer and direct it to the Router’ s HTML interface using its LAN IP address. If this is the first time you are accessing the web-based manager you must type its default IP address, 192.168.0.1 in the address bar of the browser. The URL in the address bar should read: http://192.168.0.1. If you change the IP address you will use the new IP address to access the web-based manager.

In the page that opens, click on the Login to web-based management module button. A new window will appear and you will be prompted for a user name and password. Use default user name

admin and password admin for first time set up.

1. In Windows, click on the START button, go to Settings and choose

Control Panel.

Note

2. In the Control Panel window, double-click on the Internet Options icon.

3. Click the Connections tab and click on the LAN Settings button.

NAT Configuration

Network Address Translation (NAT) is a routing protocol that allows your network to become a private network that is isolated from, yet connected to the Internet. It does this by changing the IP address of packets from a global IP address usable on the Internet to a local IP address usable on your private network (but not on the Internet) and vice-versa. The Router allows up to 128 host IP addresses.

NAT has two major benefits. First, NAT allows many users to access the Internet using a single global IP address. This can greatly reduce the costs associated with Internet access and helps alleviate the current shortage of Internet IP addresses. Secondly, the NAT process creates an added degree of security by hiding your private network behind one IP address. The NAT function will normally only allow incoming packets that are generated in response to a request from a host within the LAN.

If your network uses web servers, FTP servers or other proxies used for data requests from outside the private network, you can use NAT in conjunction with Port Redirection to allow appropriate use of your servers by outside users. See the section on Port Redirection for more information.

For the purposes of network administration, NAT is almost indispensable. Hosts and servers on the internal network can be moved easily. Using NAT together with DHCP can greatly reduce the workload of a network manager while allowing tremendous flexibility.

To view the NAT Configuration menu, click on the NAT Configuration button:

Figure 4 - 5. NAT Configuration Menu

The following parameters can be configured using the NAT Configuration menu:

NAT Function

DMZ State

DMZ IP Address

Default = enabled. Select enabled or disabled to enable or disable the NAT function.

Default = disabled. Select enabled or disabled to enable or disable the DMZ function.

With the DMZ State enabled, type in the LAN IP address of a designated DMZ device (see explanation below).

Page 42

DSL-504 ADSL Router User’s Guide

DMZ IP Address

NAT may conflict with certain interactive applications such as video conferencing or playing Internet video games. For these applications, a NAT bypass can be set up using a DMZ IP address. The DMZ IP address is a

“ visible” address and does not benefit from the full protection of the NAT function. Therefore it is advisable that other security precautions be enabled to protect the other computers and devices on the LAN. It may be wise to use isolate the device with the DMZ IP address from the rest of the LAN.

For example, if you want to use video conferencing and still use NAT, you can use the DMZ IP address function. In this case, you must have a PC or server through which video conferencing will take place. The IP address of this PC or server will then be the DMZ IP address. You can designate the server’ s IP address as the DMZ by typing in the IP address in the DMZ IP Address space provided and clicking the OK button.

For the system that uses the DMZ IP address, you may want to manually assign an IP address to it and adjust your DHCP server addresses so that the DMZ IP address is not included in the DHCP server range. This way you avoid possible IP address problems if you reboot the DMZ system.

IP Masquerade Pass Through

Since certain protocols have difficulty operating in conjunction with NAT, the Router can forward these packets without subjecting them to NAT address mapping. In particular, IPsec (a special network security protocol) and PPTP (a tunneling protocol used for virtual private networks) are not compatible with NAT. For this reason, the Router is configured to allow them to pass by default. You may disable this using the IP Masquerade Pass Through menu. To block in effect either packet type while NAT is running you must deselect the type here and click the OK button.

Figure 4 - 6. IP Masquerade Pass Through

Page 43

DSL-504 ADSL Router User’s Guide

IP Masquerade Timer

The IP Masquerade Timer is used to control how frequently the IP Masquerade table is updated. The IP Masquerade table is used to map the internal LAN IP addresses to the external WAN global IP address used for your account. If you are familiar with Ethernet switching, you can think of the IP Masquerade Timer as being similar to a MAC address table timeout in a switch.

Figure 4 - 7. IP Masquerade Timer

To change the IP Masquerade for the default settings, select the time for TCP or UDP packets from their respective drop-down menus and click the OK button.

Port Redirection

DSL-504 ADSL Router User’s Guide

Figure 4 - 8. Port Redirection Menu

The Port Redirection feature of the Router is used in conjunction with NAT or IP Masquerading to improve security and efficiency. Port redirection can 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. Other common applications might include directing incoming SMTP packets to an Email server for data scrutiny and improved network efficiency.

Port Redirection can be used to redirect TCP or UDP packets to a specified port and a specified IP address on your local network. 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.

The user changeable variables available for Port Redirection are listed in the table below.

Page 45

DSL-504 ADSL Router User’s Guide

Port redirection is universally enabled or disabled for the Router with the Port Redirection State drop-down menu. The Existing Entry number tells you how many sets currently are configured. The Valid Entry number tells you the number of sets that are active.

Advanced Filter & Firewall

One of the most important elements of any network security implementation is the firewall. Packet filtering is a basic firewall security measure and should be used on any network that is exposed to security risk. A packet filter system examines data packets and scrutinizes them in order to control network access. Filtering rules determine whether packets are passed through the Router from either side of the gateway. The rules are created and controlled by the network administrator and can be precisely defined. These rules are used to block access to the LAN from outside the network and/or to deny access to the WAN from within the network. The Router uses filtering rules to examine data packet headers for specific information. Packets passing through the Router that do not meet the criteria specified by the rule set are dropped.

In order to improve network security without severely limiting network efficiency, it is important to carefully plan the sets of access rules. Effective implementation of packet filtering requires detailed knowledge of network services and communication protocols. An overly complicated filtering scheme can adversely affect Router performance, while an inadequate set of rules may needlessly compromise security.

Filtering rules can be precisely defined based upon source and destination IP address, as well as port and protocol information.

Figure 4 - 10. Filter & Firewall Main Menu

The Existing Entry number tells you how many routes are currently configured. The Valid Entry number tells you the number of routes that are enabled. Filtering can be universally enabled or disabled with the drop-down IP Filter State drop-down menu.

Page 48

packets form that IP address. < specifies the port numbers less than and equal to the Start Port number > specifies the port numbers greater than and equal to the Start Port number = sets the port number equal to the Start Port if there is no End Port specified; if an End Port number

is specified, this defines a range of ports to filter. The range is defined as the port numbers between the Start Port and End Port, including the Start and End Port numbers.

Start Port

For a range of ports, this will be the first port in the range. For a single port

enter the port number.

End Port

Destination

For a range of ports, this will be the last port in the range. For a single port just

enter the same port number entered in Start Port.

Type in the destination IP address and select the Subnet Mask to pass or block

packets destined to that IP address.

To delete or modify an existing rule, select the index number and click the action button for Delete or Modify. Clicking on the Clear button will set the variables to the blank or default setting.

Each new rule that is added will appear in the entry table at the top of the web page. When you have configured all the rules you want to use, click on the Apply button. You can save and reboot the system now, or continue to configure the Router.

Date & Time Settings

The Router can use Network Time Protocol (NTP) to set system time and date accurately using a public or private NTP server. The function may be disabled if highly accurate time recording is not a priority.

Figure 4 - 12. Date & Time Configuration

If you wish to use NTP to set system time and date following these steps:

1. Make sure NTP enabled is displayed in the NTP State drop-down menu.

2. Type in an NTP server IP address that can be used by the Router. Keep in mind that many NTP servers

require permission before they may be used.

3. Select the Time Zone where the Router is located or the time zone you want to use for system time.

Time zones are displayed as GMT (Greenwich Mean Time) plus or minus hours incremented by whole hours.

4. Click the Set Time button to set the time with the chosen NTP server. This will send a request to update

system time and date. NTP update packets are sent periodically to ensure precision.

If you prefer to use to use the timer located in the computer you are using to configure the Router:

1. Select Set time with local PC time in the NTP State drop-down menu.

2. Click the Set Time button to set the time with your computer.

ATM Loopback Test

ATM loopback tests are used to verify connectivity and path integrity along a specified ATM circuit. In the test, a cell is sent to an endpoint or to the end of the first segment of the ATM path. If the path is available and the connections are functioning, an test cell will be returned along the same ATM path and be detected by the device. This is very similar to a Ping test. The test can help to determine if connectivity problems originate from outside the LAN.

Figure 4 - 14. ATM Loopback Screen

To perform the test, define the following parameters:

VPI

VCI

F4/F5

etoe/segment

Status

Type in the VPI setting used for the network connection. Type in the VCI setting used for the network connection. Choose F4 (Virtual Path) or F5 (Virtual Connection) from the pull-down menu to

define the flow type. An F4 flow test is used to verify that ATM network information (ATM cells) can be shared between network elements. This information is used within virtual paths to report an unavailable path or a virtual path that cannot be guaranteed. An F5 flow test is also used to verify that ATM network information can be shared between network elements. This information is used within virtual connections to report degraded virtual channel performance such as late arriving cells, lost cells, and cell insertion problems.

Select the test type from the remaining pull-down menu. Choose End-to-End to test the entire path from the Router to the ATM connection endpoint. Choose segment to test the path from the Router to the end of the first ATM connection segment.

A success or fail message appears here after the test is completed. If the reply cell is received within the standard-defined time, the Status will read OK. This indicates that the specified test path is functioning normally and all connections were successful. If the Status reads Fail, there is a fault in the segment or path tested.

When all the test parameters have been specified, click on the Loop Test button to initiate the test.

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 POTS (Plain Old Telephone Service) 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 or near the distribution cabinet. 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 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 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.
