Select the appropriate option
Automatic discovery
- Select this to have the TW100-BRF114U
contact the PC and find its MAC address. This is only possible if
the PC is connected to the LAN and powered On.
MAC is
- Enter the MAC address on the PC. The MAC address is
also called the "Hardware Address", "Physical Address", or "Net-
work Adapter Address". The TW100-BRF114U uses this to
provide a unique identifier for each PC. Because of this, the MAC
address can NOT be left blank.

the PC is connected to the LAN, and powered on.

If enabled, this feature allows you to manage the TW100-BRF114U via the Internet.

Management
Enable to allow management via the Internet. If Disabled, this device
will ignore management connection attempts from the Internet.
Port Number
Enter a port number between 1024 and 65535 (8080 is recom-
mended). 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 prevent the use of a Web "Virtual
Server" on your LAN. (See
Advanced Internet - Virtual Servers
)
Current IP Ad-
dress
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-
BRF114U. 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.

Routing
Overview
If you don't have other Routers or Gateways on your LAN, you can ignore the "Routing"
page completely.
If the TW100-BRF114U 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-BRF114U
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-BRF114U, 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.

Properties
Destination Network
- The network address of the remote LAN
segment. For standard class "C" LANs, the network address is
the first 3 fields of the Destination IP Address. The 4th (last)
field can be left at 0.
Network Mask
- The Network Mask for the remote LAN
segment. For class "C" networks, the default mask is
255.255.255.0
Gateway IP Address
- The IP Address of the Gateway or
Router which the Broadband Router must use to communicate
with the destination above. (NOT the router attached to the re-
mote segment.)
Metric
- The number of "hops" (routers) to pass through to
reach the remote LAN segment. The shortest path will be used.
The default value is 1.

Add
Add a new entry to the Static Routing table, using the data shown in
the "Properties" area on screen. The entry selected in the list is
ignored, and has no effect.
Update
Update the current Static Routing Table entry, using the data shown
in the "Properties" area on screen.
Delete
Delete the current Static Routing Table entry.
Clear Form
Clear all data from the "Properties" area, ready for input of a new
entry for the Static Routing table.
Generate Report
Generate a read-only list of all entries in the Static Routing table.
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-
BRF114U, 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-BRF114U as the
Default Route
or
Default Gateway
.
Local Router
The local router is the Router installed on the same LAN segment as the TW100-BRF114U.
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
Normally 0.0.0.0, but check your router documentation.
Network Mask
Normally 0.0.0.0, but check your router documentation.
Gateway IP Address
The IP Address of the TW100-BRF114U.
