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.

If "Automatic discovery" (for MAC address) is selected, the PC will be

sent a "ping" to determine its hardware address. This will fail unless

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

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

Enable Remote

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.

- 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.

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.
