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 Address 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 Protocol), 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 su ch
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.

Page 7
Introduction
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 TW100BRF114 incorporates protection against DoS attacks.

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 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

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.
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).
• 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 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.

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. 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-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.

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 TW100BRF114.
The first step is to check the PC's TCP/IP settings.
The TW100-BRF114 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-BRF114 settings, and the default Windows
TCP/IP settings, no changes need to be made.
• By default, the TW100-BRF114 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-BRF114
• 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 - Other
Features and Operations for details.

Communication Applications
Most applications are supported transparently by the TW100-BRF114. But sometimes it is not
clear which PC should receive an incoming connection. This problem could arise with the
Communication Applications listed on this screen.
If this problem arises, you can use this screen to set which PC should receive an incoming
connection, as described below.
Communication Applications
Select an Application
Send incoming calls to
This lists applications which may generate incoming connections,
where the destination PC (on your local LAN) is unknown.
This lists the PCs on your LAN.
• If necessary, you can add PCs manually, using the "PC
Database" option on the advanced menu.
• For each application listed above, you can choose a destina-
tion PC.
• There is no need to "Save" after each change; you can set the
destination PC for each application, then click "Save".
Special Applications
If you use Internet applications which use non-standard connections or port numbers, you may
find that they do not function correctly because they are blocked by the TW100-BRF114 's
firewall. In this case, you can define the application as a "Special Application".
Special Applications Screen
This screen can be reached by clicking the Special Applications button on the Advanced
Internet screen.
You can then define your Special Applications. You will need detailed information about the
application; this is normally available from the supplier of the application.
Also, note that the terms "Incoming" and "Outgoing" on this screen refer to traffic from the
client (PC) viewpoint.

• Type - Select the protocol (TCP or UDP) used when you receive data
from the special application or service. (Note: Some applications use
different protocols for outgoing and incoming data).
• Start - Enter the beginning of the range of port numbers used by the
application server, for data you receive. If the application uses a single
port number, enter it in both the "Start" and "Finish" fields.
• Finish - Enter the end of the range of port numbers used by the applica-
tion server, for data you receive.
• Type - Select the protocol (TCP or UDP) used when you send data to
the remote system or service.
• Start - Enter the beginning of the range of port numbers used by the
application server, for data you send to it. If the application uses a single port number, enter it in both the "Start" and "Finish" fields.
• Finish - Enter the end of the range of port numbers used by the applica-
tion server, for data you send to it. If the application uses a single port
number, enter it in both the "Start" and "Finish" fields.
Using a Special Application
• Configure the Special Applications screen as required.
• On your PC, use the application normally. Remember that only one (1) PC can use each
Special application at any time. Also, when 1 PC is finished using a particular Special Application, there may need to be a "Time-out" before another PC can use the same Special
Application. The "Time-out" period may be up to 3 minutes.
44
Page 49
Internet Features
If an application still cannot function correctly,
try using the "DMZ" feature.
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 almost any application to be used on the "DMZ PC".
• The "DMZ PC" will receive all "Unknown" connections and data.
• If the DMZ feature is enabled, you must select the PC to be used as the "DMZ PC".
• The DMZ feature can be Enabled and Disabled on the Advanced Internet screen.
The "DMZ PC" is effectively outside the Firewall, making it more vulnerable to attacks. For this reason, you
should only enable the DMZ feature when required.

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 TW100-BRF114 's DDNS screen.
4. The TW100-BRF114 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.
Dynamic DNS Screen
Select Internet on the main menu, then Dynamic DNS, to see a screen like the following:

MAC Address
The MAC (hardware) address is a low-level network identifier. It may be called "MAC Address", "Hardware Address", or "Physical Address". On a PC, this address is associated with
the Network card or adapter. The address on the MAC Address screen is the address on the
Internet (WAN port) interface, and has no effect on the LAN interface.
• If your ISP asks for the "Network Adapter Address", "Physical Address", "Hardware
Address", or "MAC Address" for the PC the DSL/Cable modem is connected to, provide
this value.
• If your ISP has already recorded a MAC address, you can change the address used by the
Firewall Router to match the address recorded by your ISP.

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.
Figure 32: 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.

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.

Overview
The Access Control feature allows administrators to restrict the level of Internet Access available to PCs on your LAN. With the default settings, everyone has unrestricted Internet access.
To use this feature:
1. Set the desired restrictions on the "Default" group. All PCs are in the "Default" group
unless explicitly moved to another group.
2. Set the desired restrictions on the other groups ("Group 1", "Group 2", "Group 3" and
"Group 4") as needed.
3. Assign PC to the groups as required.
Restrictions are imposed by blocking "Services", or types of
connections. All common Services are pre-defined.
If required, you can also define your own Services.

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 preven t the use of a Web "Virtual
Server" on your LAN. (See Advanced Internet - Virtual Servers)
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 TW100-
BRF114. 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.

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.
Figure 39: 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-BRF114 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.

ICMP
If enabled, DoS (Denial of Service) attacks will be detected and
blocked. The default is enabled. It is strongly recommended that this
setting be left enabled.
Note:
• A DoS attack does not attempt to steal data or damage your PCs,
but overloads your Internet connection so you can not use it - the
service is unavailable.
• This device uses "Stateful Inspection" technology. This system
can detect situations where individual TCP/IP packets are valid,
but collectively they become a DoS attack.
This setting affects the number of "half-open" connections allowed.
• A "half-open" connection arises when a remote client contacts the
Server with a connection request, but then does not reply to the
Server's response.
• While the optimum number of "half-open" connections allowed
(the "Threshold") depends on many factors, the most important
factor is the available bandwidth of your Internet connection.
• Select the setting to match the bandwidth of your Internet connec-
tion.
The ICMP protocol is used by the "ping" and "traceroute" programs,
and by network monitoring and diagnostic programs.
• If checked, the Firewall Router will repond to ICMP packets
received from the Internet.
• If not checked, ICMP packets from the Internet will be ignored.
Disabling this option provides a slight increase in security.

Routing
Overview
• If you don't have other Routers or Gateways on your LAN, you can ignore the "Routing"
page completely.
• If the TW100-BRF114 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-BRF114 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-BRF114, 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 Other screen.
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 TW100BRF114, 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-BRF114 as the Default Route or
Default Gateway.
Local Router
The local router is the Router installed on the same LAN segment as the TW100-BRF114.
This router requires that the Default Route is the TW100-BRF114 itself. Typically, routers
have a special entry for the Default Route. It should be configured as follows.
Destination IP Address
Network Mask
Normally 0.0.0.0, but check your router documentation.
Normally 0.0.0.0, but check your router documentation.
Gateway IP Address
Metric
The IP Address of the TW100-BRF114.

Other Routers on the Local LAN
Other routers on the local LAN must use the TW100-BRF114 's Local Router as the Default
Route. The entries will be the same as the TW100-BRF114 's local router, with the exception
of the Gateway IP Address.
• For a router with a direct connection to the TW100-BRF114 's local Router, the Gateway
IP Address is the address of the TW100-BRF114 's local router.
• For routers which must forward packets to another router before reaching the TW100-
BRF114 's local router, the Gateway IP Address is the address of the intermediate router.

Troubleshooting
This Appendix covers the most likely problems and their solutions.
Overview
This chapter covers some common problems that may be encountered while using the TW100BRF114 and some possible solutions to them. If you follow the suggested steps and the
TW100-BRF114 still does not function properly, contact your dealer for further advice.
General Problems
Problem 1:
Solution 1:
Can't connect to the TW100-BRF114 to configure it.
Check the following:
• The TW100-BRF114 is properly installed, LAN connections are OK,
and it is powered ON.
• Ensure that your PC and the TW100-BRF114 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 compatible with the TW100-BRF114 '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-BRF114.
In Windows, you can check these settings by using Control Panel-
Network to check the Properties for the TCP/IP protocol.

Appendix A - Troubleshooting
Problem 1:
Solution 1:
Problem 2:
Solution 2:
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.
• 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-BRF114. 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.)
• If the TW100-BRF114 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 TW100-BRF114.
The TW100-BRF114 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.
