Chapter 1
Introduction
This Chapter provides an overview of the Wireless Router's features and ca-
pabilities.
Congratulations on the purchase of your new Wireless Router. The Wireless 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.
•Wireless Access Point for 802.11a, 802.11b and 802.11gWireless Stations.
Figure 1: Wireless Router
Wireless Router Features
The Wireless 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 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).
•DSL & Cable Modem Support. The Wireless Router has a 10/100BaseT Ethernet port
for connecting a DSL or Cable Modem. All popular DSL and Cable Modems are supported.
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. Unnumbered IP with PPPoE is also supported.

•Fixed or Dynamic IP Address. On the Internet (WAN port) connection, the Wireless
Router supports both Dynamic IP Address (IP Address is allocated on connection) and
Fixed IP Address.
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 ap-
plications 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.
•DDNS Support. DDNS (Dynamic DNS) allows Internet users to connect to Virtual
Servers on your LAN using a domain name, even if your IP address is not fixed.
•Multi-DMZ. For each WAN (Internet) IP address allocated to you, 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 in-
compatible 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.
•Access Control. Using the Access Control feature, you can assign LAN users to differ-
ent groups, and determine which Internet services are available to each group.
•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 Router complies with the IEEE802.11aand
IEEE802.11g(DSSS) specifications for Wireless LANs.
•Supports 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 802.11gmaximum of 54Mbps are supported.
•WPA-PSK support. The WPA-PSK (Pre-shared Key) standard provides greater security
for your Wireless clients than WEP.
•WEP support. Support for WEP (Wired Equivalent Privacy) is included. Key sizes of 64
Bit and 128 Bit are supported.
•Wireless MAC-level 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.

Introduction

LAN Features
•4-Port Switching Hub. The Wireless Router incorporates a 4-port 10/100BaseT switch-
ing 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 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 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 configura-
tion.
•Configuration File Upload/Download. Save (download) the configuration data from
the Wireless Router to your PC, and restore (upload) a previously-saved configuration file
to the Wireless Router.
•Remote Management. The Wireless 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 Router to perform a Ping or DNS
lookup.
•UPnP Support. UPnP (Universal Plug and Play) allows automatic discovery and con-
figuration of the Wireless 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.
•Wireless LAN Security. WPA-PSK and WEP (Wired Equivalent Privacy) are supported,
as well as MAC-level Wireless access control to prevent unknown wireless stations from
accessing your LAN.
•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 Wireless 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.
•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 Wireless
Router incorporates protection against DoS attacks.

If you can't connect
If the Wireless Router does not respond, check the following:
•The Wireless 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 Wireless 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 Wireless 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 Wireless Router are on the same network segment.

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") net-
works. For other networks, use the Subnet Mask for the LAN segment
to which the Wireless Router is attached (the same value as the PCs on
that LAN segment).
DHCP Server •If Enabled, the Wireless Routerwill 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 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.
