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 Address 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.

Broadband ADSL Router User Guide
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 dynamic 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-

If you can't connect
If the TW100-BRM504 does not respond, check the following:
• The TW100-BRM504 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 TW100-BRM504'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 TW100-BRM504'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 TW100-BRM504 are on the same network segment. (If you don't have a router, this must be the case.)

IP address for the TW100-BRM504, 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 TW100-BRM504 is attached (the same value as
the PCs on that LAN segment).
• 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 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.
13
Broadband ADSL Router User Guide
• 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.

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 TW100BRM504.
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 required:
• 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 reconfigure the Router itself. Refer to Chapter 8 - Ad-
vanced Setup for details.
16
PC Configuration
Checking TCP/IP Settings - Windows 9x/ME:
1. Select Control Panel - Network. You should see a screen like the following:
Figure 9: Network Configuration
2. Select the TCP/IP protocol for your network card.
3. Click on the Properties button. You should then see a screen like the following.
Figure 10: IP Address (Win 95)
Ensure your TCP/IP settings are correct, as follows:
Using DHCP
To use DHCP, select the radio button Obtain an IP Address automatically. This is the default
Windows setting. Using this is recommended. By default, the TW100-BRM504 will act as a
DHCP Server.
Restart your PC to ensure it obtains an IP Address from the TW100-BRM504.
Using "Specify an IP Address"
If your PC is already configured, check with your network administrator before making the
following changes:
17
