Chapter 1
Introduction
This Chapter provides an overview of the Broadband Router's features and
capabilities.
Congratulations on the purchase of your new Broadband Router. The Broadband Router is a
multi-function device providing the following services:
•
Shared Broadband Internet Access for all LAN users.
•
4-Port Switching Hub for 10BaseT or 100BaseT connections.
Figure 1: Broadband Router
Broadband Router Features
The Broadband 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 Broadband Router, using only a single external IP Address. The local (invalid)
IP Addresses are hidden from external sources. This process is called NAT (Network Ad-
dress Translation).
•
DSL & Cable Modem Support. The Broadband Router has a 10BaseT Ethernet port
for connecting a DSL or Cable Modem. All popular DSL and Cable Modems are sup-
ported. SingTel RAS and Big Pond (Australia) login support is also included.
• PPPoE, PPTP, SingTel RAS and Telstra Big Pond Support. The Internet (WAN
port) connection supports PPPoE (PPP over Ethernet), PPTP (Peer-to-Peer Tunneling Pro-
tocol), SingTel RAS and Telstra Big Pond (Australia), as well as "Direct Connection" type
services.
•
Fixed or Dynamic IP Address. On the Internet (WAN port) connection, the Broad-
band Router supports both Dynamic IP Address (IP Address is allocated on connection)
and Fixed IP Address.

Broadband Router User Guide
Advanced Internet Functions
• Communication Applications. Support for Internet communication applications, such
as interactive Games, Telephony, and Conferencing applications, which are often difficult
to use when behind a Firewall, is included.
•
Special Internet Applications. 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.
•
DMZ. One (1) PC on your local LAN can be configured to allow unrestricted 2-way
communication with Servers or individual users on the Internet. This provides the ability
to run programs which are incompatible with Firewalls.
•
URL Filter. Use the URL Filter to block access to undesirable Web sites by LAN users.
•
Internet Access Log. See which Internet connections have been made.
•
VPN Pass through Support. PCs with VPN (Virtual Private Networking) software
using PPTP, L2TP and IPSec are transparently supported - no configuration is required.
LAN Features
• 4-Port Switching Hub. The Broadband 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 Broadband 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 Broadband Router's RIP (Routing Information Protocol) support and built-in static
routing table.
Configuration & Management
• Easy Setup. Use your WEB browser from anywhere on the LAN or WLAN for configu-
ration.
•
Remote Management. The Broadband 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.
• UPnP Support. UPnP (Universal Plug and Play) allows automatic discovery and con-
figuration of the Broadband Router. UPnP is by supported by Windows ME, XP, or later.
Security Features
• Password - protected Configuration . Optional password protection is provided to
prevent unauthorized users from modifying the configuration data and settings.
•
NAT Protection. An intrinsic side effect of NAT (Network Address Translation) tech-
nology 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 Broadband Router.
•
Stateful Inspection Firewall. All incoming data packets are monitored and all incom-
ing server requests are filtered, thus protecting your network from malicious attacks from
external sources.
2

Installation
•
Protection against DoS attacks. DoS (Denial of Service) attacks can flood your
Internet connection with invalid packets and connection requests, using so much band-
width and so many resources that Internet access becomes unavailable. The Broadband
Router incorporates protection against DoS attacks.

Broadband Router User Guide
Configuration Program
The Broadband Router contains an HTTP server. This enables you to connect to it, and con-
figure it, using your Web Browser. Your Browser must support JavaScript. The
configuration program has been tested on the following browsers:
• Netscape V4.08 or later
• Internet Explorer V4 or later
Preparation
Before attempting to configure the Broadband Router, please ensure that:
• Your PC can establish a physical connection to the Broadband Router. The PC and the
Broadband Router must be directly connected (using the Hub ports on the Broadband
Router) or on the same LAN segment.
• The Broadband Router must be installed and powered ON.
• If the Broadband Router's default IP Address (192.168.0.1) is already used by another
device, the other device must be turned OFF until the Broadband Router is allocated a new
IP Address during configuration.
Using UPnP
If your Windows system supports UPnP, an icon for the Broadband Router will appear in the
system tray, notifying you that a new network device has been found, and offering to create a
new desktop shortcut to the newly-discovered device.
• Unless you intend to change the IP Address of the Broadband Router, you can accept the
desktop shortcut.
• Whether you accept the desktop shortcut or not, you can always find UPnP devices in My
Network Places (previously called Network Neighborhood).
• Double - click the icon for the Broadband Router (either on the Desktop, or in My Net-
work Places) to start the configuration. Refer to the following section Setup Wizard for
details of the initial configuration process.
Using your Web Browser
To establish a connection from your PC to the Broadband Router:
1. After installing the Broadband Router in your LAN, start your PC. If your PC is already
running, restart it.
2. Start your WEB browser.
3. In the Address box, enter "HTTP://" and the IP Address of the Broadband Router, as in
this example, which uses the Broadband Router's default IP Address:
HTTP://192.168.0.1
8

Setup
If you can't connect
If the Broadband Router does not respond, check the following:
• The Broadband Router is properly installed, LAN connection is OK, and it is
powered ON. You can test the connection by using the "Ping" command:
• Open the MS-DOS window or command prompt window.
• Enter the command:
ping 192.168.0.1
If no response is received, either the connection is not working, or your
PC's IP address is not compatible with the Broadband Router's IP Address.
(See next item.)
• If your PC is using a fixed IP Address, its IP Address must be within the range
192.168.0.2 to 192.168.0.254 to be compatible with the Broadband Router's
default IP Address of 192.168.0.1. Also, the Network Mask must be set to
255.255.255.0. See Chapter 4 - PC Configuration for details on checking your
PC's TCP/IP settings.
• Ensure that your PC and the Broadband Router are on the same network
segment. (If you don't have a router, this must be the case.)

TCP/IP
IP Address IP address for the Broadband 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.
Subnet Mask 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 Broadband Router is attached (the same value as
the PCs on that LAN segment).
DHCP Server • If Enabled, the Broadband 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 Broadband Router as the default Gateway. See the fol-
lowing 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.

Broadband Router User Guide
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).
• The DHCP Server provides the Gateway and DNS addresses to the client, as well as
allocating an IP Address.
• The Broadband 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 Broadband 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 Broadband 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 Broadband Router's, the following procedure is required.
1. Disable the DHCP Server feature in the Broadband Router. This setting is on the LAN
screen.
2. Configure the DHCP Server to provide the Broadband Router's IP Address as the Default
Gateway.
To Configure your PCs to use DHCP
This is the default setting for TCP/IP under Windows 95/98/ME.
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
Windows Clients
This section describes how to configure Windows clients for Internet access via the Broadband
Router.
The first step is to check the PC's TCP/IP settings.
The Broadband 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 Broadband Router settings, and the default Windows
TCP/IP settings, no changes need to be made.
• By default, the Broadband 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 re-
quired:
• The Gateway must be set to the IP address of the Broadband Router
• The DNS should be set to the address provided by your ISP.
If your LAN has a Router, the LAN Administrator must re-
configure the Router itself. Refer to Chapter 8 - Ad-
vanced 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 8: 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 9: 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 Broadband Router will act as a
DHCP Server.
Restart your PC to ensure it obtains an IP Address from the Broadband Router.
Using "Specify an IP Address"
If your PC is already configured, check with your network administrator before making the
following changes:
