Introduction
Congratulations on the purchase of your new WL-108/109 Broadband
Router. The WL-108/109 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.
4-Port Switching Hub for 10BaseT or 100BaseT connections.
WL-108/109 Features
The WL-108/109 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 WL-108/WL-109 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 WL-108/WL-109 Wireless ADSL Router
has a built-in ADSL modem, supporting all common ADSL connections.
IPoA, PPPoE, PPPoA, Direct Connection Support. The WL-
108/WL-109 Wireless ADSL Router supports all common connection
methods.
Auto-detection of Internet Connection Method. The WL-108/WL-
109 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 (WAN port)
connection, the WL-108/WL-109 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.
Virtual Servers. This feature allows Internet users to access Internet
servers on your LAN. The required setup is quick and easy.
URL Filter. Use the URL Filter to block access to undesirable Web sites
by LAN users.
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.
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.
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.
WL-108 Wireless Network Modem/router 11M

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 WL-108/109 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.
Wireless MAC Access Control. The Wireless Access Control feature
can check the 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 WL-108/109 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 WL-
108/109 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 WL-108/109'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 for
configuration.
Configuration File Upload/Download. Save (download) the
configuration data from the WL-108/109 to your PC, and restore
(upload) a previously-saved configuration file to the WL-108/109.
Remote Management. The WL-108/109 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 WL-108/WL-109 Wireless
ADSL Router to perform a Ping or DNS lookup.
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 (Wired Equivalent Privacy) is 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) technology is that by allowing all LAN users to share a
WL-108 Wireless Network Modem/router 11M
7
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 WL-108/109.
Stateful Inspection 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 WL-108/109 incorporates
protection against DoS attacks.

Data - LAN Screen
TCP/IP
IP Address
IP address for the WL-108/109, 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 WL-108/109 is attached (the same value as the
PCs on that LAN segment).
DHCP Server
If Enabled, the WL-108/109 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 WL-108/109 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.

Cancel
The "Cancel" button will discard any data you have entered and reload
the file from the WL-108/109.
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 WL-108/109 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 WL-108/109'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 WL-108/109'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 WL-108/109's, the following
procedure is required.
1. Disable the DHCP Server feature in the WL-108/109. This setting is on
the LAN screen.
2. Configure the DHCP Server to provide the WL-108/109's IP Address as
the Default Gateway.

Port Number
Enter a port number between 1024 and 65535 (8080 is
recommended). This port number must be specified when you
connect (see below).
Note: The default port number for HTTP (Web) connections is port
80, but using port 80 here will prevent the use of a Web "Virtual
Server" on your LAN. (See Advanced Internet - Virtual Servers)
Current IP
Address
You must use this IP Address to connect (see below).
This IP Address is allocated by your ISP. But if using a Dynamic IP
Address, this value can change each time you connect to your ISP.
So it is better if your ISP allocates you a Fixed IP Address.

To connect from a remote PC via the Internet
1. Ensure your Internet connection is established, and start your Web
Browser.
2. In the "Address" bar, enter "HTTP://" followed by the Internet IP
Address of the WL-108/109. If the port number is not 80, the port
number is also required. (After the IP Address, enter ":" followed by the
port number.)
e.g.
HTTP://123.123.123.123:8080
This example assumes the WAN IP Address is 123.123.123.123, and the
port number is 8080.

41
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.
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.
WL-108 Wireless Network Modem/router 11M

Virtual Servers Screen
The Virtual Servers screen is reached by the Virtual Servers link on the

Select the PC for this Server. The PC must be running the
appropriate Server software.
For each entry, the PC must be

software.
If the desired Server type is not
listed, you can define your own
Servers, using the Firewall Rules.
From the Internet, ALL Virtual
Servers have the IP Address
allocated by your ISP.
WL-108 Wireless Network Modem/router 11M
43
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,
described in the following section, to allow users to connect to your Virtual
Servers using a URL, rather than an IP Address.
WL-108 Wireless Network Modem/router 11M
44
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.
The Service works as follows:
1. You must register for the service at http://www.dyndns.org
(Registration is free). Your password will be E-mailed to you.
2. After registration, use the "Create New Host" option (at
www.dyndns.org) to request your desired Domain name.
3. Enter your data from www.dyndns.org in the WL-108/109's DDNS
screen.
4. The WL-108/109 will then automatically ensure that your current IP
Address is recorded at http://www.dyndns.org
5. 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.

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.
PC Database Screen
An example PC Database screen is shown below.
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 WL-108/109 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.
