Introduction
This chapter provides an overview of the Wireless Router's features and capabilities.
Congratulations on the purchase of your new Wireless Router. The Wireless Router is a multifunction device providing the following services:
Shared Broadband Internet Access for all LAN users.
•
4-Port Switching Hub for 10BaseT or 100BaseT connections.
•
Wireless Router for 802.11b and 802.11g Wireless Stations.
•
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 Protocol), 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 that 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.
•
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.
Introduction
• 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 that 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.
•
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 IEEE802.11g (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 and WPA support. Support for WEP and WPA is included.
•
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 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 configu-
ration.
•
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. WEP and WPA are 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) 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 bandwidth and so many resources that Internet access becomes unavailable. The Wireless
Router incorporates protection against DoS attacks.

IP address for the Wireless 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 Router is attached (the same value as
the PCs on that LAN segment).
• If Enabled, the Wireless 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 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.
Save the data on screen.
Cancel
The "Cancel" button will discard any data you have entered and reload
the file from the Wireless Router.
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 Wireless 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 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 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 Router's, the following procedure is required.
1. Disable the DHCP Server feature in the Wireless Router. This setting is on the LAN
screen.
2. Configure the DHCP Server to provide the Wireless Router's IP Address as the Default
Gateway.
Wireless Screen
The Wireless Router's settings must match the other Wireless stations.
Note that the Wireless Router will automatically accept both 802.11b and 802.11g connec-
tions, and no configuration is required for this feature.
To change the Wireless Router's default settings for the Wireless Router feature, use the
Wireless link on the main menu to reach the Wireless screen. An example screen is shown
below.
