TW100-BRM504 Features
The TW100-BRM504 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 TW100-BRM504, using only a single external IP Address. The local (invalid)
IP Addresses are hidden from external sources. This process is called NAT (Network Ad-
dress Translation).
•
•
•
Built-in ADSL Modem. The TW100-BRM504 has a built-in ADSL modem, supporting
all common ADSL connections.
IPoA, PPPoE, PPPoA, Direct Connection Support. The TW100-BRM504 supports
all common connection methods.
Auto-detection of Internet Connection Method. In most situations, the TW100-
BRM504 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 TW100-
BRM504 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 connec-
tions 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 dy-
namic IP address which changes every time you connect.
•
VPN Pass through Support. PCs with VPN (Virtual Private Networking) software
using PPTP, L2TP and IPSec are transparently supported - no configuration is required.
LAN Features
•
4-Port Switching Hub. The TW100-BRM504 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 TW100-BRM504 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 configu-
ration.
•
Configuration File Upload/Download. Save (download) the configuration data from
the TW100-BRM504 to your PC, and restore (upload) a previously-saved configuration
file to the TW100-BRM504.
•
•
Remote Management. The TW100-BRM504 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 TW100-BRM504 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.
•
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 TW100-BRM504.
•
•
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 band-

Address from within the range used by your LAN.
IP Address
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 TW100-BRM504 is attached (the same value as
the PCs on that LAN segment).
Subnet Mask
DHCP Server
•
If Enabled, the TW100-BRM504 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 TW100-BRM504 as the default Gateway. See the follow-
ing 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.

•
•
The TW100-BRM504 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 TW100-BRM504'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 TW100-BRM504'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 TW100-BRM504's, the following procedure is required.
1. Disable the DHCP Server feature in the TW100-BRM504. This setting is on the LAN
screen.
2. Configure the DHCP Server to provide the TW100-BRM504'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.

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
Windows Clients
This section describes how to configure Windows clients for Internet access via the TW100-
BRM504.
The first step is to check the PC's TCP/IP settings.
The TW100-BRM504 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 TW100-BRM504 settings, and the default Windows
TCP/IP settings, no changes need to be made.
•
•
By default, the TW100-BRM504 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 re-
quired:
•
•
The Gateway must be set to the IP address of the TW100-BRM504
The DNS should be set to the address provided by your ISP.
If your LAN has a Router, the LAN Administrator must re-
configure the Router itself. Refer to Chapter 8 - Ad-
vanced Setup for details.

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 35: 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

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).

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.
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.

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 37: 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 TW100-BRM504 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 re-
quired.

Routing
Overview
•
•
•
If you don't have other Routers or Gateways on your LAN, you can ignore the "Routing"
page completely.
If the TW100-BRM504 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 TW100-BRM504 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 seg-
ments 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
TW100-BRM504, 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 TW100-
BRM504, 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 TW100-BRM504 as the Default Route or
Default Gateway.
Local Router
The local router is the Router installed on the same LAN segment as the TW100-BRM504.
This router requires that the Default Route is the TW100-BRM504 itself. Typically, routers
have a special entry for the Default Route. It should be configured as follows.

Other Routers on the Local LAN
Other routers on the local LAN must use the TW100-BRM504's Local Router as the Default
Route. The entries will be the same as the TW100-BRM504's local router, with the exception
of the Gateway IP Address.
•
For a router with a direct connection to the TW100-BRM504's local Router, the Gateway
IP Address is the address of the TW100-BRM504's local router.
•
For routers which must forward packets to another router before reaching the TW100-

Appendix A
Troubleshooting
A
This Appendix covers the most likely problems and their solutions.
Overview
This chapter covers some common problems that may be encountered while using the TW100-
BRM504 and some possible solutions to them. If you follow the suggested steps and the
TW100-BRM504 still does not function properly, contact your dealer for further advice.
General Problems
Problem 1:
Can't connect to the TW100-BRM504 to configure it.
Check the following:
Solution 1:
•
•
•
•
The TW100-BRM504 is properly installed, LAN connections are OK,
and it is powered ON.
Ensure that your PC and the TW100-BRM504 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 com-
patible with the TW100-BRM504's default IP Address of 192.168.0.1.
Also, the Network Mask should be set to 255.255.255.0 to match the
TW100-BRM504.
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:
When I enter a URL or IP address I get a time out error.
A number of things could be causing this. Try the following troubleshooting
steps.
Solution 1:
•
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
TW100-BRM504. 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 TW100-BRM504's status screen to see if it is working
correctly.
Problem 2:
Some applications do not run properly when using the TW100-
BRM504.
