Known PCs
This lists all current entries. Data displayed is
name (IP Address) type
.
The "type" indicates whether the PC is connected to the LAN.
Name
If adding a new PC to the list, enter its name here. It is best if this
matches the PC's "hostname".

IP Address
Select the appropriate option:
Automatic
- The PC is set to be a DHCP client (Windows: "Ob-
tain an IP address automatically"). The TW100-BRV204 will
allocate an IP address to this PC when requested to do so. The IP
address could change, but normally won't.
DCHP Client - Reserved IP Address
- Select this if the PC is set
to be a DCHP client, and you wish to guarantee that the TW100-
BRV204 will always allocate the same IP Address to this PC.
Enter the required IP address. Only the last field is required; the
other fields must match the TW100-BRV204.
Fixed IP Address
- Select this if the PC is using a Fixed (Static)
IP address. Enter the IP address allocated to the PC. (The PC must
be configured to use this IP address.)
MAC Address
Select the appropriate option
Automatic discovery
- Select this to have the TW100-BRV204
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-BRV204 uses this to provide
a unique identifier for each PC. Because of this, the MAC address
can NOT be left blank.
Add as New
Entry
Add a new PC to the list, using the data in the "Properties" box.
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.
Update Selected
PC
Update (modify) the selected PC, using the data in the "Properties"
box.
Clear Form
Clear the "Properties" box, ready for entering data for a new PC.
Refresh
Update the data on screen.
Generate Report
Display a read-only list showing full details of all entries in the PC
database.

Remote Administration
This feature allows you to manage the TW100-BRV204 via the Internet.
Figure 94: Remote Administration Screen
Data - Remote Administration Screen
Enable Remote
Administration
Enable to allow administration via the Internet. If Disabled, this
device will ignore management connection attempts from the Inter-
net.
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 Address
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-
BRV204. If the port number is not 80, the port number is also required. (After the IP Ad-
dress, 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-BRV204 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-BRV204 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-BRV204, 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.

Enable RIP
Check this to enable the RIP (Routing Information Protocol) feature
of the TW100-BRV204.
The TW100-BRV204 supports RIP 1 only.
Static Routing
Table Entries
This list shows all entries in the Routing Table.
The "Properties" area shows details of the selected item in the
list.
Change any the properties as required, then click the "Update"
button to save the changes to the selected entry.
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 TW100-BRV204 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.
