Wireless ADSL Router Features

The Wireless ADSL Router incorporates many advanced features, carefully designed to provide sophisticated functions while being easy to use.

Internet Access Features

• Shared Internet Access. All users on the LAN or WLAN can access the Internet

through the Wireless ADSL Router, using only a single external IP Address. The local (invalid) IP Addresses are hidden from external sources. This process is called NAT (Network Address Translation).

Built-in ADSL Modem. The Wireless ADSL Router has a built-in ADSL modem,

•

supporting all common ADSL connections.

•

IPoA, PPPoE, PPPoA, Direct Connection Support. The Wireless ADSL Router

supports all common connection methods.

Wireless ADSL Router User Guide

Auto-detection of Internet Connection Method. The Wireless ADSL Router can test

•

your ADSL and Internet connection to determine the connection method used by your ISP.

•

Fixed or Dynamic IP Address. On the Internet (WAN port) connection, the Wireless

ADSL Router supports both Dynamic IP Address (IP Address is allocated on connection) and Fixed IP Address.

Advanced Internet Functions

• Application Level Gateways (ALGs). Applications which use non-standard

connections or port numbers are normally blocked by the Firewall. The ability to define and allow such applications is provided, to enable such applications to be used normally.

Virtual Servers. This feature allows Internet users to access Internet servers on your

•

LAN. The required setup is quick and easy.

•

URL Filter. Use the URL Filter to block access to undesirable Web sites by LAN users. Logs. Define what data is recorded in the Logs, and optionally send log data to a Syslog

•

Server. Log data can also be E-mailed to you.

•

Firewall. As well as the built-in firewall to protect your LAN, you can define Firewall

Rules to determine which incoming and outgoing traffic should be permitted.

•

Dynamic DNS Support. DDNS, when used with the Virtual Servers feature, allows

users to connect to Servers on your LAN using a Domain Name, even if you have a dynamic IP address which changes every time you connect.

•

VPN Pass through Support. PCs with VPN (Virtual Private Networking) software

using PPTP, L2TP and IPSec are transparently supported - no configuration is required.

Wireless Features

• Standards Compliant. The Wireless ADSL Router complies with the IEEE802.11g

(DSSS) specifications for Wireless LANs.

•

Supports both 802.11b and 802.11g Wireless Stations. The 802.11g standard

provides for backward compatibility with the 802.11b standard, so both 802.11b and

802.11g Wireless stations can be used simultaneously.

Speeds to 54Mbps. All speeds up to the 802.11g maximum of 54Mbps are supported.

•

WEP support. Support for WEP (Wired Equivalent Privacy) is included. Key sizes of

•

64 Bit and 128 Bit are supported.

•

Wireless MAC Access Control. The Wireless Access Control feature can check the

MAC address (hardware address) of Wireless stations to ensure that only trusted Wireless Stations can access your LAN.

Simple Configuration. If the default settings are unsuitable, they can be changed

•

quickly and easily.

LAN Features

• 4-Port Switching Hub. The Wireless ADSL Router incorporates a 4-port 10/100BaseT

switching hub, making it easy to create or extend your LAN.

•

DHCP Server Support. Dynamic Host Configuration Protocol provides a dynamic IP

address to PCs and other devices upon request. The Wireless ADSL Router can act as a DHCP Server for devices on your local LAN and WLAN.

•

Multi Segment LAN Support. LANs containing one or more segments are supported,

via the Wireless ADSL Router's RIP (Routing Information Protocol) support and built-in static routing table.

Introduction

Configuration & Management

• Easy Setup. Use your WEB browser from anywhere on the LAN or WLAN for

configuration.

•

Configuration File Upload/Download. Save (download) the configuration data from

the Wireless ADSL Router to your PC, and restore (upload) a previously-saved configuration file to the Wireless ADSL Router.

Remote Management. The Wireless ADSL Router can be managed from any PC on

•

your LAN. And, if the Internet connection exists, it can also (optionally) be configured via the Internet.

Network Diagnostics. You can use the Wireless ADSL Router to perform a Ping or

•

DNS lookup.

Security Features

• Password - protected Configuration. Optional password protection is provided to

prevent unauthorized users from modifying the configuration data and settings.

•

Wireless LAN Security. WEP (Wired Equivalent Privacy) is supported, as well as

Wireless access control to prevent unknown wireless stations from accessing your LAN.

•

NAT Protection. An intrinsic side effect of NAT (Network Address Translation)

technology is that by allowing all LAN users to share a single IP address, the location and even the existence of each PC is hidden. From the external viewpoint, there is no network, only a single device - the Wireless ADSL Router.

Firewall. All incoming data packets are monitored and all incoming server requests are

•

filtered, thus protecting your network from malicious attacks from external sources.

•

Protection against DoS attacks. DoS (Denial of Service) attacks can flood your

Internet connection with invalid packets and connection requests, using so much bandwidth and so many resources that Internet access becomes unavailable. The Wireless ADSL Router incorporates protection against DoS attacks.

IP Address

Subnet Mask

DHCP Server

DHCP

IP address for the Wireless ADSL Router, as seen from the local LAN. Use the default value unless the address is already in use or your LAN is using a different IP address range. In the latter case, enter an unused IP Address from within the range used by your LAN.

The default value 255.255.255.0 is standard for small (class "C") networks. For other networks, use the Subnet Mask for the LAN segment to which the Wireless ADSL Router is attached (the same value as the PCs on that LAN segment).

• If Enabled, the Wireless ADSL Router will allocate IP Addresses to PCs (DHCP clients) on your LAN when they start up. The default (and recommended) value is Enabled.

• If you are already using a DHCP Server, this setting must be Disabled, and the existing DHCP server must be re-configured to treat the Wireless ADSL Router as the default Gateway. See the following section for further details.

• The Start IP Address and Finish IP Address fields set the values used by the DHCP server when allocating IP Addresses to DHCP clients. This range also determines the number of DHCP clients supported.

See the following section for further details on using DHCP.

What DHCP Does

A DHCP (Dynamic Host Configuration Protocol) Server allocates a valid IP address to a DHCP Client (PC or device) upon request.

• The client request is made when the client device starts up (boots).

Wireless ADSL Router User Guide

• The DHCP Server provides the Gateway and DNS addresses to the client, as well as allocating an IP Address.

• The Wireless ADSL Router can act as a DHCP server.

• Windows 95/98/ME and other non-Server versions of Windows will act as a DHCP client.

This is the default Windows setting for the TCP/IP network protocol. However, Windows uses the term Obtain an IP Address automatically instead of "DHCP Client".

• You must NOT have two (2) or more DHCP Servers on the same LAN segment. (If your LAN does not have other Routers, this means there must only be one (1) DHCP Server on your LAN.)

Using the Wireless ADSL Router's DHCP Server

This is the default setting. The DHCP Server settings are on the LAN screen. On this screen, you can:

• Enable or Disable the Wireless ADSL Router's DHCP Server function.

• Set the range of IP Addresses allocated to PCs by the DHCP Server function.

You can assign Fixed IP Addresses to some devices while using DHCP, provided that the Fixed IP Addresses are NOT within the range used by the DHCP Server.

Using another DHCP Server

You can only use one (1) DHCP Server per LAN segment. If you wish to use another DHCP Server, rather than the Wireless ADSL Router's, the following procedure is required.

1. Disable the DHCP Server feature in the Wireless ADSL Router. This setting is on the LAN screen.

2. Configure the DHCP Server to provide the Wireless ADSL Router's IP Address as the Default Gateway.

To Configure your PCs to use DHCP

This is the default setting for TCP/IP for all non-Server versions of Windows. See Chapter 4 - Client Configuration for the procedure to check these settings.

Chapter 4

PC Configuration

This Chapter details the PC Configuration required on the local ("Internal") LAN.

Overview

For each PC, the following may need to be configured:

• TCP/IP network settings

• Internet Access configuration

• Wireless configuration

Windows Clients

This section describes how to configure Windows clients for Internet access via the Wireless ADSL Router.

The first step is to check the PC's TCP/IP settings. The Wireless ADSL Router uses the TCP/IP network protocol for all functions, so it is

essential that the TCP/IP protocol be installed and configured on each PC.

TCP/IP Settings - Overview

If using the default Wireless ADSL Router settings, and the default Windows TCP/IP settings, no changes need to be made.

• By default, the Wireless ADSL Router will act as a DHCP Server, automatically providing a suitable IP Address (and related information) to each PC when the PC boots.

• For all non-Server versions of Windows, the default TCP/IP setting is to act as a DHCP client.

If using a Fixed (specified) IP address, the following changes are required:

• The Gateway must be set to the IP address of the Wireless ADSL Router

• The DNS should be set to the address provided by your ISP.

If your LAN has a Router, the LAN Administrator must reconfigure the Router itself. Refer to Chapter 8 - Advanced Setup for details.

PC Configuration

Checking TCP/IP Settings - Windows 9x/ME:

1. Select Control Panel - Network. You should see a screen like the following:

Figure 11: Network Configuration

2. Select the TCP/IP protocol for your network card.

3. Click on the Properties button. You should then see a screen like the following.

Figure 12: IP Address (Win 95)

Ensure your TCP/IP settings are correct, as follows:

Using DHCP

To use DHCP, select the radio button Obtain an IP Address automatically. This is the default Windows setting. Using this is recommended. By default, the Wireless ADSL Router will act as a DHCP Server.

Restart your PC to ensure it obtains an IP Address from the Wireless ADSL Router.

Using "Specify an IP Address"

If your PC is already configured, check with your network administrator before making the following changes:

Wireless ADSL Router User Guide

• On the Gateway tab, enter the Wireless ADSL Router's IP address in the New Gateway field and click Add, as shown below. Your LAN administrator can advise you of the IP Address they assigned to the Wireless ADSL Router.
