TW100-BRF114 Features
The TW100-BRF114 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-BRF114, 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).
•DSL & Cable Modem Support. The TW100-BRF114 has a 10/100BaseT Ethernet
port for connecting a DSL or Cable Modem. All popular DSL and Cable Modems are
supported. SingTel RAS and Big Pond (Australia) login support is also included.
•PPPoE, PPTP, SingTel RAS and Telstra Big Pond Support. The Internet (WAN
port) connection supports PPPoE (PPP over Ethernet), PPTP (Peer-to-Peer Tunneling Pro-
tocol), SingTel RAS and Telstra Big Pond (Australia), as well as "Direct Connection" type
services.
•Fixed or Dynamic IP Address. On the Internet (WAN port) connection, the TW100-
BRF114 supports both Dynamic IP Address (IP Address is allocated on connection) and
Fixed IP Address.

Advanced Internet Functions
•Communication Applications. Support for Internet communication applications, such
as interactive Games, Telephony, and Conferencing applications, which are often difficult
to use when behind a Firewall, is included.
•Special Internet Applications. 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.
•DMZ. One (1) PC on your local LAN can be configured to allow unrestricted 2-way
communication with Servers or individual users on the Internet. This provides the ability
to run programs which are incompatible with Firewalls.
•URL Filter. Use the URL Filter to block access to undesirable Web sites by LAN users.
•Internet Access Log. See which Internet connections have been made.
•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-BRF114 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-BRF114 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 TW100-BRF114 '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 or WLAN for configu-
ration.
•Remote Management. The TW100-BRF114 can be managed from any PC on your
LAN. And, if the Internet connection exists, it can also (optionally) be configured via the
Internet.
•UPnP Support. UPnP (Universal Plug and Play) allows automatic discovery and confi-
guration of the TW100-BRF114. UPnP is by supported by Windows ME, XP, or later.
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-BRF114.
•Stateful Inspection Firewall. All incoming data packets are monitored and all incom-
ing server requests are filtered, thus protecting your network from malicious attacks from
external sources.
2

Introduction
•Protection against DoS attacks. DoS (Denial of Service) attacks can flood your
Internet connection with invalid packets and connection requests, using so much band-
width and so many resources that Internet access becomes unavailable. The TW100-
BRF114 incorporates protection against DoS attacks.

Using your Web Browser
To establish a connection from your PC to the TW100-BRF114:
1. After installing the TW100-BRF114 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 TW100-BRF114, as in this
example, which uses the TW100-BRF114 's default IP Address:
HTTP://192.168.0.1
If you can't connect
If the TW100-BRF114 does not respond, check the following:
•The TW100-BRF114 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-BRF114 '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-BRF114 's de-
fault 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-BRF114 are on the same network seg-
ment. (If you don't have a router, this must be the case.)

Data - LAN Screen
TCP/IP
IP Address IP address for the TW100-BRF114, 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 TW100-BRF114 is attached (the same value as
the PCs on that LAN segment).
DHCP Server •If Enabled, the TW100-BRF114 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-BRF114 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.
Buttons
Save Save the data on screen.
Cancel The "Cancel" button will discard any data you have entered and reload
the file from the TW100-BRF114.

Setup
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-BRF114 can act as a DHCP server.
•Windows 95/98/ME2000/XP 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. How-
ever, 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-BRF114 '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-BRF114 '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-BRF114 's, the following procedure is required.
1. Disable the DHCP Server feature in the TW100-BRF114. This setting is on the LAN
screen.
2. Configure the DHCP Server to provide the TW100-BRF114 's IP Address as the Default
Gateway.
To Configure your PCs to use DHCP
This is the default setting for TCP/IP under Windows 95/98/ME/NT4.0/2000/XP.
See Chapter 4 - Client Configuration for the procedure to check these settings.
