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.

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.
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.
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
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 ADSL Router are on the same network
segment. (If you don't have a router, this must be the case.)
•
Ensure you are using the wired LAN interface. The Wireless interface can only
be used if its configuration matches your PC's wireless settings.

Data - LAN Screen
TCP/IP
IP Address
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.
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 Wireless ADSL Router is attached (the same
value as the PCs on that LAN segment).
DHCP Server
•
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.
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.

WPA Encryption
The WPA-PSK standard allows different encryption methods to be
used. Select the desired option. Wireless Stations must use the same

Router
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.
Modem
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.)
•

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.

This screen provides access to the DMZ, Special Applications and URL Filter features.
Figure 49: Internet Screen
DMZ
This feature, if enabled, allows the DMZ computer on your LAN to be exposed to all users on
the Internet.
57
Wireless ADSL Router User Guide
•
This allows almost any application to be used on the "DMZ PC".
•
The "DMZ PC" will receive all "Unknown" connections and data.
•
If the DMZ feature is enabled, you must select the PC to be used as the "DMZ PC".
The "DMZ PC" is effectively outside the Firewall,
making it more vulnerable to attacks. For this reason,
you should only enable the DMZ feature when required.
Special Applications
If you use Internet applications which use non-standard connections or port numbers, you may
find that they do not function correctly because they are blocked by the Wireless Router's
firewall. In this case, you can define the application as a "Special Application".
The Special Applications screen can be reached by clicking the Special Applications button on
the Internet screen.
You can then define your Special Applications. You will need detailed information about the
application; this is normally available from the supplier of the application.
Also, note that the terms "Incoming" and "Outgoing" on this screen refer to traffic from the
client (PC) viewpoint

application server, for data you receive. If the application uses a single
port number, enter it in both the "Start" and "Finish" fields.
•
Finish - Enter the end of the range of port numbers used by the
application server, for data you receive.
•
Type - Select the protocol (TCP or UDP) used when you send data to
the remote system or service.
•
Start - Enter the beginning of the range of port numbers used by the
application server, for data you send to it. If the application uses a
single port number, enter it in both the "Start" and "Finish" fields.
•
Finish - Enter the end of the range of port numbers used by the
application server, for data you send to it. If the application uses a
single port number, enter it in both the "Start" and "Finish" fields.
Using a Special Application
•
Configure the Special Applications screen as required.
•
On your PC, use the application normally. Remember that only one (1) PC can use each
Special application at any time. Also, when 1 PC is finished using a particular Special
Application, there may need to be a "Time-out" before another PC can use the same
Special Application. The "Time-out" period may be up to 3 minutes.
URL Filter
If you want to limit access to certain sites on the Internet, you can use this feature. The URL
filter will check each Web site access. If the address, or part of the address, is included in the
block site list, access will be denied.
On the Advanced Internet screen, select the desired setting:
•
Disable - disable this feature.
•
Block By Schedule - block according to the settings on the Schedule page.
•
Block Always - allow blocking all of the time, independent of the Schedule page.
Click the Configure URL Filter button to open the URL Filter screen, allowing you to create
or modify the filter strings which determine which sites will be blocked.
The URL Filter screen is displayed when the Configure URL Filter button on the Advanced

Advanced Features
Dynamic DNS (Domain Name Server)
This free service is very useful when combined with the Virtual Server feature. It allows
Internet users to connect to your Virtual Servers using a URL, rather than an IP Address.
This also solves the problem of having a dynamic IP address. With a dynamic IP address, your
IP address may change whenever you connect, which makes it difficult to connect to you.
DDNS Services work as follows:
1.
2.
3.
4.
5.
You must register for the service at one of the listed DDNS Service providers.
After registration, use the Service provider's normal procedure to obtain your desired
Domain name.
Enter your DDNS data on the Wireless ADSL Router's DDNS screen, and enable the
DDNS feature.
The Wireless ADSL Router will then automatically ensure that your current IP Address is
recorded at the DDNS service provider's Domain Name Server.
From the Internet, users will be able to connect to your Virtual Servers (or DMZ PC)
using your Domain name, as shown on this screen.
Dynamic DNS Screen
Select Advanced on the main menu, then Dynamic DNS, to see a screen like the following:

The Firewall Rules screen allows you to define "Firewall Rules" which can allow or prevent
certain traffic. "Traffic" means incoming connection attempts, not packets.
By default:
•
All Outgoing traffic is permitted.
•
All Incoming traffic is denied.
Because of this default behavior, any Outgoing rules will generally Block traffic, and
Incoming rules will generally Allow traffic.

Advanced Features
Virtual Servers
This feature, sometimes called Port Forwarding, allows you to make Servers on your LAN
accessible to Internet users. Normally, Internet users would not be able to access a server on
your LAN because:
•
Your Server does not have a valid external IP Address.
•
Attempts to connect to devices on your LAN are blocked by the firewall in this device.
The "Virtual Server" feature solves these problems and allows Internet users to connect to your
servers, as illustrated below.
Figure 60: Virtual Servers
IP Address seen by Internet Users
Note that, in this illustration, both Internet users are connecting to the same IP Address, but
using different protocols.
To Internet users, all virtual Servers on your LAN have the same IP Address.
This IP Address is allocated by your ISP.
This address should be static, rather than dynamic, to make it easier for Internet users to
connect to your Servers.
However, you can use the DDNS (Dynamic DNS) feature to allow users to connect to your
Virtual Servers using a URL, instead of an IP Address.
Virtual Servers Screen
•
The "Virtual Servers" feature allows Internet Users to access PCs on your LAN.
•
The PCs must be running the appropriate Server Software.
•
For Internet Users, ALL of your Servers have the same IP address. This IP address is
allocated by your ISP.
•
To make it easier for Internet users to connect to your Servers, you can use the "DDNS"
feature. This allows Internet users to connect to your Servers with a URL, rather than an
IP address. This technology works even if your ISP allocates dynamic IP addresses (IP
address is allocated upon connection, so it may change each time you connect).

For each entry, the PC must be running the
appropriate Server software.
If the desired Server type is not listed, you can define
your own Servers, using the Firewall Rules.
Connecting to the Virtual Servers
Once configured, anyone on the Internet can connect to your Virtual Servers. They must use
the Internet IP Address (the IP Address allocated to you by your ISP).
e.g.
http://203.70.212.52
ftp://203.70.212.52
It is more convenient if you are using a Fixed IP Address from your ISP, rather than Dynamic.
However, you can use the Dynamic DNS feature to allow users to connect to your Virtual
Servers using a URL, rather than an IP Address.
From the Internet, ALL Virtual Servers have
the IP Address allocated by your ISP

Advanced Features
VPN Setup
The VPN (Virtual Private Network) feature in the Wireless ADSL Router allows you to create
a VPN connection between 2 Wireless ADSL Routers, or a remote PC to establish a VPN
connection to the Wireless ADSL Router.
To establish a VPN connection from a remote PC to the Wireless ADSL Router, you need
suitable (IPSec) VPN client software on your PC.
For more information about VPNs, please refer to Appendix C - About VPNs.
VPN Policies
A "VPN Policy" contains all the configuration data for a particular VPN connection. Generally,
you will have to create one policy for each site you wish to connect to. The remote VPN
Gateway (or client) needs to have matching configuration.
•
Traffic covered by an enabled policy will automatically be sent via a VPN tunnel. If the
VPN tunnel does not exist, it will be created.
•
The VPN tunnel is created according to the parameters in the SA (Security Association).
•
The remote VPN Endpoint must have a matching SA, or it will refuse the connection.
There are 2 types of VPN Policies:
•
Manual - All settings (including the keys) for the VPN tunnel are manually input at each
end (both VPN Endpoints).
•
Auto - Some parameters for the VPN tunnel are generated automatically. This requires
using the IKE (Internet Key Exchange) protocol to perform negotiations between the 2
VPN Endpoints.

An "Auto" VPN policy uses the IKE (Internet Key Protocol) to exchange and negotiate
parameters for the IPsec SA (Security Association). Because of this negotiation, it is not
necessary for all settings on this VPN Gateway to match the settings on the remote VPN
endpoint. Where settings must match, this is indicated.

no input is required.)
SA Parameters
Encryption
Encryption Algorithm used for both IKE and IPSec. This setting
must match the setting used on the remote VPN Gateway.
Authentication
Authentication Algorithm used for both IKE and IPSec. This
setting must match the setting used on the remote VPN Gateway.
Pre-shared Key
The key must be entered both here and on the remote VPN
Gateway. This method does not require using a CA (Certificate
Authority).
SA Life Time
This determines the time interval before the SA (Security
Association) expires. (It will automatically be re-established if
necessary.) While using a short time period (or data amount)
increases security, it also degrades performance. It is common to
use periods over an hour (3600 seconds) for the SA Life Time. This
setting applies to both IKE and IPSec SAs.
IPSec PFS (Perfect
Forward Secrecy)
If enabled, security is enhanced by ensuring that the key is changed
at regular intervals. Also, even if one key is broken, subsequent
keys are no easier to break. (Each key has no relationship to the
previous key.)
This setting applies to both IKE and IPSec SAs. When configuring
the remote endpoint to match this setting, you may have to specify
the "Key Group" used. For this device, the "Key Group" is the
same as the "DH Group" setting in the IKE section.

Overview
Normally, it is not necessary to use these screens, or change any settings. These screens and
settings are provided to deal with non-standard situations, or to provide additional options for
advanced users.
The available settings and features are:
PC Database
This is the list of PCs shown when you select the "DMZ PC" or a
"Virtual Server". This database is maintained automatically, but
you can add and delete entries for PCs which use a Fixed (Static)
IP Address.

Wireless ADSL Router User Guide
PC Database
The PC Database is used whenever you need to select a PC (e.g. for the "DMZ" PC).
•
It eliminates the need to enter IP addresses.
•
Also, you do not need to use fixed IP addresses on your LAN.
However, if you do use a fixed IP address on some devices on your LAN, you should enter
details of each such device into the PC database, using the PC Database screen.
PC Database Screen
An example PC Database screen is shown below.
Figure 66: PC Database
•
PCs which are "DHCP Clients" are automatically added to the database, and updated as
required.
•
By default, non-Server versions of Windows act as "DHCP Clients"; this setting is called
"Obtain an IP Address automatically".
•
The Wireless ADSL Router uses the "Hardware Address" to identify each PC, not the
name or IP address. The "Hardware Address" can only change if you change the PC's
network card or adapter.
•
This system means you do NOT need to use Fixed (static) IP addresses on your LAN.
However, you can add PCs using Fixed (static) IP Addresses to the PC database if
required.

Wireless ADSL Router User Guide
Routing
Overview
•
If you don't have other Routers or Gateways on your LAN, you can ignore the "Routing"
page completely.
•
If the Wireless ADSL Router is only acting as a Gateway for the local LAN segment,
ignore the "Routing" page even if your LAN has other Routers.
•
If your LAN has a standard Router (e.g. Cisco) on your LAN, and the Wireless ADSL
Router is to act as a Gateway for all LAN segments, enable RIP (Routing Information
Protocol) and ignore the Static Routing table.
•
If your LAN has other Gateways and Routers, and you wish to control which LAN
segments use each Gateway, do NOT enable RIP (Routing Information Protocol).
Configure the Static Routing table instead. (You also need to configure the other Routers.)
•
If using Windows 2000 Data center Server as a software Router, enable RIP on the
Wireless ADSL Router, and ensure the following Windows 2000 settings are correct:
•
Open Routing and Remote Access
•
In the console tree, select Routing and Remote Access , [server name], IP Routing,
RIP
•
In the "Details" pane, right-click the interface you want to configure for RIP version 2,
and then click "Properties".
•
On the "General" tab, set Outgoing packet protocol to "RIP version 2 broadcast", and
Incoming packet protocol to "RIP version 1 and 2".
Routing Screen
The routing table is accessed by the Routing link on the Administration menu.
Using this Screen
Generally, you will use either RIP (Routing Information Protocol) OR the Static Routing Table,
as explained above, although is it possible to use both methods simultaneously.
Static Routing Table
•
If RIP is not used, an entry in the routing table is required for each LAN segment on your
Network, other than the segment to which this device is attached.
•
The other Routers must also be configured. See Configuring Other Routers on your LAN
later in this chapter for further details and an example.

Configuring Other Routers on your LAN
It is essential that all IP packets for devices not on the local LAN be passed to the Wireless
ADSL Router, so that they can be forwarded to the external LAN, WAN, or Internet. To
achieve this, the local LAN must be configured to use the Wireless ADSL Router as the
Default Route or Default Gateway.
97
Wireless ADSL Router User Guide
Local Router
The local router is the Router installed on the same LAN segment as the Wireless ADSL
Router. This router requires that the Default Route is the Wireless ADSL Router itself.
Typically, routers have a special entry for the Default Route. It should be configured as follows.
Destination IP Address
Normally 0.0.0.0, but check your router documentation.
Network Mask
Normally 0.0.0.0, but check your router documentation.
Gateway IP Address
The IP Address of the Wireless ADSL Router.
Metric
Other Routers on the Local LAN
Other routers on the local LAN must use the Wireless ADSL Router's Local Router as the
Default Route. The entries will be the same as the Wireless ADSL Router's local router, with
the exception of the Gateway IP Address.
•
For a router with a direct connection to the Wireless ADSL Router's local Router, the
Gateway IP Address is the address of the Wireless ADSL Router's local router.
•
For routers which must forward packets to another router before reaching the Wireless
ADSL Router's local router, the Gateway IP Address is the address of the intermediate
router.

When this device restarts in Modem mode, the IP address does not change, but the DHCP
server is disabled. However, your PC will usually retain the IP address provided by the DHCP
Server, so the connection will be automatically re-established. You then need to ensure that the
IP address of this modem is suitable for your LAN.
•
You need to have a DHCP Server on your LAN to provide IP addresses to the Wireless
clients using this Access Point.
•
This Modem/AP must be a valid device on your LAN, to allow management connections.
You must assign a (fixed) IP address which is within the address range used on your LAN,
but not within the address range used by your DHCP server.
When you connect in future, just connect normally, using the IP address you assigned.

Device Mode
Select the desired device mode for the router:
•
Router - 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.
•
Modem - 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.
This mode is also called Bridge Mode.
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.
Operation
Operation is automatic and transparent.
• Wireless clients can connect to the Access Point if they have the correct SSID and security,
but they must obtain an IP address from the DHCP Server on your LAN.
•
The modem will act like any other ADSL modem. No routing will be performed, and no
client login will be done. If a client login is required, it must be performed by your
Router/Gateway or by software on your PC.

Appendix A
Troubleshooting
This Appendix covers the most likely problems and their solutions.
Overview
This chapter covers some common problems that may be encountered while using the Wireless
ADSL Router and some possible solutions to them. If you follow the suggested steps and the
Wireless ADSL Router still does not function properly, contact your dealer for further advice.
General Problems
Problem 1:
Can't connect to the Wireless ADSL Router to configure it.
Solution 1:
Check the following:
•
The Wireless ADSL Router is properly installed, LAN connections are
OK, and it is powered ON.
•
Ensure that your PC and the Wireless ADSL Router are on the same
network segment. (If you don't have a router, this must be the case.)
•
If your PC is set to "Obtain an IP Address automatically" (DHCP
client), restart it.
•
If your PC uses a Fixed (Static) IP address, ensure that it is using an IP
Address within the range 192.168.0.2 to 192.168.0.254 and thus
compatible with the Wireless ADSL Router's default IP Address of
192.168.0.1.
Also, the Network Mask should be set to 255.255.255.0 to match the
Wireless ADSL Router.
In Windows, you can check these settings by using Control PanelNetwork to check the Properties for the TCP/IP protocol.
Internet Access
Problem 1:
When I enter a URL or IP address I get a time out error.
Solution 1:
A number of things could be causing this. Try the following troubleshooting
steps.
•
Check if other PCs work. If they do, ensure that your PCs IP settings
are correct. If using a Fixed (Static) IP Address, check the Network
Mask, Default gateway and DNS as well as the IP Address.
•
If the PCs are configured correctly, but still not working, check the
Wireless ADSL Router. Ensure that it is connected and ON. Connect to
it and check its settings. (If you can't connect to it, check the LAN and
power connections.)
•
Check the Wireless ADSL Router's status screen to see if it is working
correctly.
106
Appendix A - Troubleshooting
Problem 2:
Some applications do not run properly when using the Wireless ADSL
Router.
Solution 2:
The Wireless ADSL Router processes the data passing through it, so it is not
transparent.
For incoming connections, you must use the Virtual Server or Firewall
Rules to specify the PC which will receive the incoming traffic.
You can also use the DMZ function. This should work with almost every
application, but:
•
It is a security risk, since the firewall is disabled.
•
Only one (1) PC can use this feature.
Wireless Access
Problem 1:
My PC can't locate the Wireless Access Point.
Solution 1:
Check the following.
•
Your PC is set to Infrastructure Mode. (Access Points are always in
Infrastructure Mode)
•
The SSID on your PC and the Wireless Access Point are the same.
Remember that the SSID is case-sensitive. So, for example
"Workgroup" does NOT match "workgroup".
•
Both your PC and the Wireless ADSL Router must have the same
setting for WEP. The default setting for the Wireless ADSL Router is
disabled, so your wireless station should also have WEP disabled.
•
If WEP is enabled on the Wireless ADSL Router, your PC must have
WEP enabled, and the key must match.
•
If the Wireless ADSL Router's Wireless screen is set to Allow Trusted
PCs only, then each of your Wireless stations must have been
designated as "Trusted", or the Wireless station will be blocked.
•
To see if radio interference is causing a problem, see if connection is
possible when close to the Wireless ADSL Router.
Remember that the connection range can be as little as 100 feet in poor
environments.
Problem 2:
Wireless connection speed is very slow.
Solution 2:
The wireless system will connect at the highest possible speed, depending
on the distance and the environment. To obtain the highest possible
connection speed, you can experiment with the following:
•
Wireless ADSL Router location.
Try adjusting the location and orientation of the Wireless ADSL
Router.
•
Wireless Channel
If interference is the problem, changing to another channel may show a
marked improvement.
•
Radio Interference
Other devices may be causing interference. You can experiment by
switching other devices Off, and see if this helps. Any "noisy" devices
should be shielded or relocated.
•
RF Shielding
107
Wireless ADSL Router User Guide
Your environment may tend to block transmission between the wireless
stations. This will mean high access speed is only possible when close
to the Wireless ADSL Router.
108
Appendix B
About Wireless LANs
This Appendix provides some background information about using Wireless
LANs (WLANs).
Modes
Wireless LANs can work in either of two (2) modes:
•
Ad-hoc
•
Infrastructure
Ad-hoc Mode
Ad-hoc mode does not require an Access Point or a wired (Ethernet) LAN. Wireless
Stations (e.g. notebook PCs with wireless cards) communicate directly with each other.
Infrastructure Mode
In Infrastructure Mode, one or more Access Points are used to connect Wireless Stations
(e.g. Notebook PCs with wireless cards) to a wired (Ethernet) LAN. The Wireless Stations
can then access all LAN resources.
Access Points can only function in "Infrastructure" mode,
and can communicate only with Wireless Stations which are
set to "Infrastructure" mode.
BSS/ESS
BSS
A group of Wireless Stations and a single Access Point, all using the same ID (SSID), form a
Basic Service Set (BSS).
Using the same SSID is essential. Devices with different SSIDs are unable to communicate
with each other.
ESS
A group of Wireless Stations, and multiple Access Points, all using the same ID (ESSID), form
an Extended Service Set (ESS).
Different Access Points within an ESS can use different Channels. In fact, to reduce
interference, it is recommended that adjacent Access Points SHOULD use different channels.
As Wireless Stations are physically moved through the area covered by an ESS, they will
automatically change to the Access Point which has the least interference or best performance.
This capability is called Roaming. (Access Points do not have or require Roaming capabilities.)
109
Wireless ADSL Router User Guide
Channels
The Wireless Channel sets the radio frequency used for communication.
•
Access Points use a fixed Channel. You can select the Channel used. This allows you to
choose a Channel which provides the least interference and best performance. In the USA
and Canada, 11 channel are available. If using multiple Access Points, it is better if
adjacent Access Points use different Channels to reduce interference.
•
In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for an
Access Point. If more than one Access Point can be used, the one with the strongest signal
is used. (This can only happen within an ESS.)
•
If using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to use the
same Channel. However, most Wireless stations will still scan all Channels to see if there
is an existing "Ad-hoc" group they can join.
WEP
WEP (Wired Equivalent Privacy) is a standard for encrypting data before it is transmitted.
This is desirable because it is impossible to prevent snoopers from receiving any data which is
transmitted by your Wireless Stations. But if the data is encrypted, then it is meaningless
unless the receiver can decrypt it.
If WEP is used, the Wireless Stations and the Access Point must have the same settings
for each of the following:
WEP
Off, 64 Bit, 128 Bit
Key
For 64 Bit encryption, the Key value must match.
For 128 Bit encryption, the Key value must match
WEP Authentication
Open System or Shared Key.
WPA-PSK
WPA-PSK is another standard for encrypting data before it is transmitted. This is a later
standard than WEP (Wired Equivalent Privacy), and provides greater security for your data.
Data is encrypted using a 256Bit key which is automatically generated and changed often.
If all your Wireless stations support WPA-PSK, you should use this instead of WEP.
If WPA-PSK is used, the Wireless Stations and the Access Point must have the same
settings for each of the following:
WPA PSK
(Pre-shared Key)
Enter the same value on every station and the AP. The PSK
must be from 8 to 63 characters in length. The 256Bit key
used for the actual encryption is derived from this key.
Encryption
The same encryption method must be used. The most
common encryption method is TKIP. Another widelysupported method is AES.
110
Appendix B - About Wireless LANs
Wireless LAN Configuration
To allow Wireless Stations to use the Access Point, the Wireless Stations and the Access Point
must use the same settings, as follows:
Mode
On client Wireless Stations, the mode must be set to "Infrastructure".
(The Access Point is always in "Infrastructure" mode.)
SSID (ESSID)
Wireless Stations should use the same SSID (ESSID) as the Access
Point they wish to connect to. Alternatively, the SSID can be set to
"any" or null (blank) to allow connection to any Access Point.
Wireless
Security
The Wireless Stations and the Access Point must use the same settings
for Wireless security. (None, WEP, WPA-PSK).
WEP: If WEP is used, the Key size (64Bit, 128Bit), Key value, and
Authentication settings must be the same on the Wireless Stations and
the Access Point.
WPA-PSK: If WPA-PSK is used, all Wireless Stations must be set to
use WPA-PSK, and have the same Pre-shared Key and encryption
system.
For Ad-hoc networks (no Access Point), all Wireless stations must
use the same security settings.
111
Appendix C
About VPNs
Overview
A VPN (Virtual Private Network) provides a secure connection between 2 points, over an
insecure network - typically the Internet. This secure connection is called a VPN Tunnel.
There are many standards and protocols for VPNs. The standard implemented in the Wireless
ADSL Router is IPSec.
IPSec
IPSec is a near-ubiquitous VPN security standard, designed for use with TCP/IP networks. It
works at the packet level, and authenticates and encrypts all packets traveling over the VPN
Tunnel. Thus, it does not matter what applications are used on your PC. Any application can
use the VPN like any other network connection.
IPsec VPNs exchange information through logical connections called SAs (Security
Associations). An SA is simply a definition of the protocols, algorithms and keys used
between the two VPN devices (endpoints).
Each IPsec VPN has two SAs - one in each direction. If IKE (Internet Key Exchange) is used
to generate and exchange keys, there are also SA's for the IKE connection as well as the IPsec
connection.
There are two security modes possible with IPSec:
•
Transport Mode - the payload (data) part of the packet is encapsulated through
encryption but the IP header remains in the clear (unchanged).
The Wireless ADSL Router does NOT support Transport Mode.
•
Tunnel Mode - everything is encapsulated, including the original IP header, and a new IP
header is generated. Only the new header in the clear (i.e. not protected). This system
provides enhanced security.
The Wireless ADSL Router always uses Tunnel Mode.
IKE
IKE (Internet Key Exchange) is an optional, but widely used, component of IPsec. IKE
provides a method of negotiating and generating the keys and IDs required by IPSec. If using
IKE, only a single key is required to be provided during configuration. Also, IKE supports
using Certificates (provided by CAs - Certification Authorities) to authenticate the identify of
the remote user or gateway.
If IKE is NOT used, then all keys and IDs (SPIs) must be entered manually, and Certificates
can NOT be used. This is called a "Manual Key Exchange".
When using IKE, there are 2 phases to creating the VPN tunnel:
•
Phase I is the negotiation and establishment up of the IKE connection.
•
Phase II is the negotiation and establishment up of the IPsec connection.
112
Appendix C - VPNs
Because the IKE and IPsec connections are separate, they have different SAs (security
associations).
Policies
VPN configuration settings are stored in Policies.
Note that different vendors use different terms. Generally, the terms "VPN Policy", "IPSec
Policy", and "IPSec Proposal" have the same meaning. However, some vendors separate IKE
Policies (Phase 1 parameters) from IPSec Policies (Phase 2 parameters).
For the Wireless ADSL Router; each VPN policy contains both Phase 1 and Phase 2
parameters (if IKE is used). Each policy defines:
•
The address of the remote VPN endpoint
•
The traffic which is allowed to use the VPN connection.
•
The parameters (settings) for the IPsec SA (Security Association)
•
If IKE is used, the parameters (settings) for the IKE SA (Security Association)
Generally, you will need at least one (1) VPN Policy for each remote site for which you wish
to establish VPN connections.
It is possible, and sometimes necessary, to have multiple Policies for the same remote site.
However, you should only Enable one (1) policy at a time.
VPN Configuration
The general rule is that each endpoint must have matching Policies, as follows:
VPN Endpoint
address
Each VPN endpoint must be configured to initiate or accept
connections to the remote VPN client or Gateway.
Usually, this requires having a fixed Internet IP address. However, it is
possible for a VPN Gateway to accept incoming connections from a
remote client where the client's IP address is not known in advance.
Local & Remote
LAN definition
This determines which outgoing traffic will cause a VPN connection
to be established, and which incoming traffic will be accepted. Each
endpoint must be configured to pass and accept the desired traffic
from the remote endpoint.
If connecting 2 LANs, this requires that:
•
Each endpoint must be aware of the IP addresses used on the
other endpoint.
•
The 2 LANs MUST use different IP address ranges.
IKE parameters
If using IKE (recommended), the IKE parameters must match (except
for the SA lifetime, which can be different).
IPsec parameters
The IPsec parameters at each endpoint must match.
113
Wireless ADSL Router User Guide
Common VPN Situations
VPN Pass-through
Figure 79: VPN Pass-through
Here, a PC on the LAN behind the Router/Gateway is using VPN software, but the
Router/Gateway is NOT acting as a VPN endpoint. It is only allowing the VPN connection.
•
The PC software can use any VPN protocol supported by the remote VPN.
•
The remote VPN Server must support client PCs which are behind a NAT router, and so
have an IP address which is not valid on the Internet.
•
The Router/Gateway requires no VPN configuration, since it is not acting as a VPN
endpoint.
Client PC to VPN Gateway
Figure 80: Client PC to VPN Server
In this situation, the PC must run appropriate VPN client software in order to connect, via the
Internet, to the Wireless ADSL Router or other VPN Gateway. Once connected, the client PC
has the same access to LAN resources as PCs on the local LAN (unless restricted by the
network administrator).
•
IPsec is not the only protocol which can be used in this situation, but the Wireless ADSL
Router supports IPsec ONLY.
•
Windows 2000 and Windows XP include an IPsec VPN client program. However,
configuration of this client program for use with the Wireless ADSL Router is very
complex and beyond the scope of this document.
114
Appendix C - VPNs
Connecting 2 LANs via VPN
Figure 81: Connecting 2 VPN Gateways
This allows two (2) LANs to be connected. PCs on each endpoint gain secure access to the
remote LAN.
•
The 2 LANs MUST use different IP address ranges.
•
The VPN Policies at each end determine when a VPN tunnel will be established, and what
systems on the remote LAN can be accessed once the VPN connection is established.
•
It is possible to have simultaneous VPN connections to many remote sites.
VPN Example
In this example, 2 LANs are connected via VPN. Each end has a Wireless ADSL Router.
Figure 82: Connecting 2 Wireless ADSL Routers
Note
•
The LANs MUST use different IP address ranges.
•
Both endpoints have fixed WAN (Internet) IP addresses.
•
This example uses an "Auto" policy, using IKE
