This Chapter provides an overview of the Wireless ADSL Router's features
and capabilities.
Congratulations on the purchase of your new Wireless ADSL Router. The Wireless ADSL
Router is a multi-function device providing the following services:
ADSL Modem.
•
Shared Broadband Internet Access for all LAN users.
•
Wireless Access Point for 802.11b and 802.11g Wireless Stations.
•
VPN Gateway to allow secure VPN connections over the Internet.
•
4-Port Switching Hub for 10BaseT or 100BaseT connections.
•
Figure 1: Wireless ADSL Router
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.
1
Wireless ADSL Router User Guide
•
IPoA, PPPoE, PPPoA, Direct Connection Support. The Wireless ADSL Router
supports all common connection methods.
•
Auto-detection of Internet Connection Method. In most situations, 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 (ADSL 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.
Special Applications. This feature, also called Port Triggering, allows you to use
•
Internet applications which normally do not function when used behind a firewall.
•
Virtual Servers. This feature allows Internet users to access Internet servers on your
LAN. The required setup is quick and easy.
•
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.
• URL Filter. Use the URL Filter to block access to undesirable Web sites by LAN users.
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.
•
Scheduling. Both the URL Filter and Firewall rules can be scheduled to operate only at
certain times. This provides great flexibility in controlling Internet -bound traffic.
•
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.
•
VPN Pass through Support. PCs with VPN (Virtual Private Networking) software
using PPTP, L2TP and IPSec are transparently supported - no configuration is required.
VPN Features
• IPSec Support. IPSec is the most common protocol.
Easy Configuration. The configuration required to allow 2 Wireless ADSL Routers to
•
establish a VPN connection between them is easy accomplished.
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. WEP encrypts any data before transmission, providing
protection against snoopers.
• WPA-PSK support. Like WEP, WPA-PSK encrypts any data before transmission,
providing protection against snoopers. The WPA-PSK is a later standard than WEP, and
provides both easier configuration and greater security than WEP.
2
Introduction
•
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.
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 or Wireless 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. Password protection is provided to prevent
unauthorized users from modifying the configuration data and settings.
•
Wireless LAN Security. WPA-PSK, WEP and Wireless access control by MAC
address are all supported. The MAC-level access control feature can be used 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.

If you can't connect
If the Wireless ADSL Router does not respond, check the following:
• The Wireless ADSL 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 ADSL 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 ADSL
Router's default IP Address of 192.168.0.1. Also, the Network Mask must be

Configuring VC2, VC3 and VC4
The Wireless ADSL Router supports multiple VCs (Virtual Circuits) on the ADSL connection.
VC1 must be used for general-purpose Internet access. The other VCs (VC2, VC3 and VC4)
are available for special purposes, such as Video-on-Demand.
You can only use these VCs if supported by your ISP and ADSL service provider. In that case,
they will provide the necessary configuration data.
Some ISP's allow multiple PPPoE connections. This allows
multiple PCs to connect to the Internet using PPPoE client
software. When using the Wireless ADSL Router, multiple
PPPoE connections are neither necessary nor supported.
To Configure additional VCs
1. Start the Setup Wizard again.
2. On the first screen, select VC2, and click "Next"

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).
• The DHCP Server provides the Gateway and DNS addresses to the client, as well as
allocating an IP Address.
17
Wireless ADSL Router User Guide
• 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.
• Disable the DHCP Server feature in the Wireless ADSL Router. This setting is on the
LAN screen.
• 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.

Wireless Screen
The Wireless ADSL Router's settings must match the other Wireless stations.
Note that the Wireless ADSL Router will automatically accept both 802.11b and 802.11g
connections, and no configuration is required for this feature.
To change the Wireless ADSL Router's default settings for the Wireless Access Point feature,
use the Wireless link on the main menu to reach the Wireless screen. An example screen is
shown below.

slow data transfers) you may need to experiment with different
channels to see which is the best.
• If using multiple Access Points, adjacent Access Points should use
different Channels to reduce interference.

If enabled, the Wireless ADSL Router will broadcast its SSID. This
allows PCs and other wireless stations to detect this Access Point and
use the correct SSID.
If disabled, PC users will have to manually enter the SSID and other
details of the wireless interface before they can connect to this Access
Point.

Use this feature to determine which Wireless stations can use the
Access Point. The options are:
• All Wireless Stations - All wireless stations can use the access
point, provided they have the correct SSID and security settings.
• Trusted Wireless stations only - Only wireless stations you
designate as "Trusted" can use the Access Point, even if they have
the correct SSID and security settings.
This feature uses the MAC address to identify Wireless stations.
The MAC address is a low-level network identifier which is
unique to each PC or network device.
To define the trusted wireless stations, use the "Set Stations"
button.
Click this button to manage the trusted PC database.

Wireless Security
This screen is accessed by clicking the "Configure" button on the Wireless screen. There are 3
options for Wireless security:
• Disabled - no data encryption is used.
• WEP - data is encrypted using the WEP standard.
• WPA-PSK - data is encrypted using the WPA-PSK standard. This is a later standard than
WEP, and provides much better security than WEP. If all your Wireless stations support
WPA-PSK, you should use WPA-PSK rather than WEP.

WPA-PSK
Like WEP, data is encrypted before transmission. WPA is more
secure than WEP, and should be used if possible. WPA-PSK is the
version of WPA, which does NOT require a Radius Server on your
LAN.
PSK
WPA Encryption
Enter the PSK (network key). Data is encrypted using a key derived
from the network key. Other Wireless Stations must use the same
network key. The PSK must be from 8 to 63 characters in length.
The WPA-PSK standard allows different encryption methods to be
used. Select the desired option. Wireless Stations must use the same
encryption method.

Router
Modem
Both the ADSL Modem and the Router features are operational. In this
mode, this device can provide shared Internet Access to all your LAN users.
Also, by default, it acts a DHCP Server, providing an IP address and related
information to all Wireless and LAN users.
Only the ADSL Modem component is operational.
• All Router features are disabled. This device is "transparent" - it does
not perform any operations or make any changes to the network traffic
passing through it.
• You need to have a DHCP Server on your LAN to provide IP addresses
to the Wireless clients using this Access Point.
• All traffic received on either the Wireless or LAN interface will be sent
over the ADSL connection.
Notes:
• Generally, you should NOT use modem mode. Only select this mode if you are sure this is
what you want.
• After changing the mode, this device will restart, which will take a few seconds. The
menu will also change, depending on the mode you are in.
• The Wireless Access Point can function in either Router or Modem mode. But generally it
is not a good idea to combine a Modem with an Access Point, because all data received
from the wireless stations will be sent over the modem connection. (Since the modem is
transparent, it does not examine the traffic to determine whether the traffic is for the LAN
or the WAN.)
• For details on using Modem Mode, see Chapter 8.
