NAT Firewall Protection
The firewall protection provided by the Broadband Router is an intrinsic side
effect of NAT (Network Address Translation). All users on the LAN share a
single external IP address. From the external viewpoint, there is no network, only
a single device.
For internal users, the Broadband Router acts as a “transparent proxy server”,
translating the multiple internal IP addresses into a single external IP address.
For external requests, any attempt to connect to local resources are blocked. The
Broadband Router will not “reverse translate” from a global IP address to a local
IP address.
This type of “natural” firewall provides an impregnable barrier against malicious
attacks.

Configuration Program
The Broadband Router contains a HTTP server. This enables you to connect to it, and configure it, using your Web Browser.
Most Browsers should work, provided they support HTML tables and forms.
Preparation
Before attempting to configure the Broadband Router, please ensure that:
• Your PC can establish a physical connection to the Broadband Router. The PC and the
Broadband Router must be directly connected (using one of the Switching Hub ports on the
Broadband Router) or on the same LAN segment.
• The Broadband Router must be installed and powered ON.
• If the Broadband Router's default IP Address (192.168.0.1) is already used by another
device, the other device must be turned OFF until the Broadband Router is allocated a new
IP Address during configuration.
Connecting to the Broadband Router
To establish a connection from your PC to the device:
1. After installing the Broadband Router in your LAN, start your PC. If your PC is already
running, restart it.
2. Start your WEB browser.
3. In the Address box, enter "HTTP://" and the IP Address of the Broadband Router, as in the
following example, which uses the Broadband Router’s default IP Address:
HTTP://192.168.0.1
4. If you have assigned a password to the Broadband Router you will be prompted for the
password, as shown below. (If no password has been set, this dialog will not appear.)
• Leave the "User Name" blank.
• Enter the password for this device, if one has been set.

If you can't connect
If the Broadband Router does not respond, check the following:
• The Broadband Router is properly installed, LAN connection is OK, and it is
powered ON.
• Ensure that your PC and the Broadband Router are on the same network
segment. (If you don't have a router, this must be the case.)
• 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 Broadband
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.
Navigation & Data Input
• Use the menu bar on the left of the screen, and the "Back" button on your Browser, for
navigation.
• Changing to another screen without clicking "Save" does NOT save any changes you may

DHCP Server
Operation
If Enabled, the Broadband Router will allocate IP Addresses to PCs on
your LAN. 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. See
Chapter 5 for further details.
Start IP Address
Finish IP Address
The IP Start Address and IP Finish Address fields set the values used
by the DHCP server.

IP Addresses
You do NOT need to enter DNS addresses UNLESS you are using a
Fixed IP Address on the WAN port. (Your ISP has allocated you a
fixed IP Address.) In this case, your ISP should recommend a DNS.
You need to enter that address or addresses here.
If using a Dynamic IP Address (DHCP Client), on the WAN port, the
DNS entries are optional.
Multiple DNS entries should be entered in the order you want them

Overview
While the Broadband Router includes a standard (static) routing table, this feature can be
completely ignored if you do not have a router in your LAN.
If you DO have a router, it is necessary to configure BOTH the Router and the Routing table in
the Broadband Router correctly, as described in the following sections.

Router Configuration
It is essential that all IP packets for devices not on the local LAN be passed to the Broadband
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 Broadband Router as the Default Route or Default
Gateway.
Local Router
The local router is the Router installed on the same LAN segment as the Broadband Router.
This router requires that the Default Route is the Broadband Router itself. Typically, routers
have a special entry for the Default Route. It should be configured as follows.
Destination IP Address
Network Mask
Gateway IP Address
Metric
Normally 0.0.0.0, but check your router
documentation.
Normally 0.0.0.0, but check your router
documentation.
The IP Address of the Broadband Router.

Other Routers on the Local LAN
Other routers on the local LAN must use the Broadband Router's Local Router as the Default
Route. The entries will be the same as the Broadband Router's local router, with the exception
of the Gateway IP Address.
• For a router with a direct connection to the Broadband Router's local Router, the Gateway
IP Address is the address of the Broadband Router's local router.
• For routers which must forward packets to another router before reaching the Broadband
Router's local router, the Gateway IP Address is the address of the intermediate router.

Virtual Servers
This feature 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.

DMZ
This feature, if enabled, allows one (1) computer on your LAN to be exposed to all users on the
Internet, allowing unrestricted 2-way communication between the "DMZ" PC and other Internet
users or Servers.
This allows connection to special-purpose servers, which require proprietary client software, or
2-way user connections such as Video-conferencing, which requires both users to run special
software.
To allow unrestricted access, the Firewall in
this device is disabled, creating a security risk.
You should use this feature only if the "Special Applications" feature is insufficient to allow an application to function correctly. This feature should be turned
ON only when needed, and left OFF the rest of the time.

• Assign a fixed IP Address to the DMZ PC, ensuring that its IP
Address is NOT within the address range allocated by the DHCP
Server.
• Reserve an IP Address for the DMZ PC in the DHCP Server,
using the Access Control - PC screen.
This is the IP Address Internet users must use to connect to the
"DMZ" PC.
This IP Address is allocated by your ISP. It is better if you are using a
fixed IP Address, so that it never changes. This will make it easier for
Internet users to connect to you. If using a Static IP Address, it is

Overview
The Access Control feature allows administrators to restrict Internet Access by individual PCs.
The process uses "Packet Filtering" to block or discard data packets. By default, no packets are
blocked or discarded.
To use this feature:
• Set the desired restrictions on the "Everyone" group.
• All PCs are in the "Everyone" group unless explicitly moved to another group, using
the PC screen.
• Generally, access rights are managed by making the "Everyone" group the
strictive
assigning a user to a less restrictive group.
However, if you wish to restrict only a small number of users, it may be more convenient to reverse this, and make the "Everyone" group the
users requiring restrictions need to be assigned to a more restrictive group.
• Set the desired restrictions on the other groups ("Group 1", "Group 2", etc ) as needed.
• For each PC you wish to move from the "Everyone" group, enter their details on the PCs
screen, and assign them to the desired group
group. Additional access rights then have to be explicitly granted by
least restrictive
most re-
group. Only
You can limit Internet access for ALL PCs without
entering ANY PC data. Simply apply the desired
restrictions to the "Everyone" group.
It is also possible to define your own packet filters, and use these filters in addition to the predefined filters. Defining your own filters is optional.

Overview
This chapter covers some common problems that may be encountered while using the
Broadband Router and some possible solutions to them. If you follow the suggested steps and
the Broadband Router still does not function properly, contact your dealer for further advice.
General Problems
A
Problem 1:
Solution 1:
Can’t connect to the Broadband Router to configure it.
Check the following:
• The Broadband Router is properly installed, LAN connections are OK,
and it is powered ON.
• Ensure that your PC and the Broadband Router are on the same
network segment. (If you don't have a router, this must be the case.)
• Ensure that your PC is using an IP Address within the range
192.168.0.2 to 192.168.0.254 and thus compatible with the Broadband
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
Broadband Router.
In Windows, you can check these settings by using Control Panel-
Network to check the Properties for the TCP/IP protocol.

Internet Access
Problem 1:
Solution 1:
Problem 2:
Solution 2:
When I enter an URL or IP address I get a time out error.
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 (IP address, Network Mask, Default gateway and DNS).
• If the PCs are configured correctly, but still not working, check the
Broadband Router. Ensure that it is connected and ON. Connect to it
and check its settings and status. (If you can't connect to it, check the
LAN and power connections.)
• If the Broadband Router is configured correctly, check your Internet
connection (DSL/Cable modem etc) to see that it is working correctly.
Some applications do not run properly when using the Broadband
Router.
The Broadband Router processes the data passing through it, so it is not
transparent.
Use the Special Applications feature to allow the use of Internet applications which do not function correctly.
If this does solve the problem you can 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.
• When the DMZ feature is being used, the Special Applications and
Virtual Server features should be disabled.
