Forwarding
Port forwarding sets up public services on your network. When users from the
Internet make certain requests of your network, the Router will forward those
requests to the appropriate computer. It is recommended that the Router's
DHCP function is disabled when Forwarding.
Forwarding is generally used to set up a webserver, ftp server, or e-mail serv-
er on your network. To add a server using Forwarding:
1.
Enter the port number used by the server. On the same line, enter the IP
Address of the server that you want the Internet users to be able to access.
2.
Configure as many entries as you would like until all of the link entries
are filled.
3.
Click the Apply button to save the settings.
Filters
Filters block specific internal users from accessing the Internet. You can set
up a filter through an IP address or a network Port number.
To Modify Filter Settings
• Enter the IP addresses you wish to filter into the IP address fields. The
users who have these IP addresses will not be able to access the Internet.
• You can also filter users by entering their network port number. Enter the
port numbers you want to filter into the port numbers fields. Users who are
connected to the Router will no longer be able to access any port number
listed there.
Block WAN Request
• By enabling the
Block WAN Request
feature, you can prevent your network
from being pinged, or detected, by other Internet users. The
Block WAN
Request
feature also adds another measure of security to your network by
hiding your network ports. Both functions of the
Block WAN Request
feature
make it more difficult for outside users to work their way into your network.

Static Routing
If the Router is connected to more than one network, it may be necessary to
set up a static route between them. A static route is a pre-determined pathway
that network information must travel to reach a specific host or network.
Click the
Show Routing Table
button to view the current static routing con-
figuration.
To create a static route entry:
1. Select
Static Route Entry
from the drop down list. The Cable/DSL
Router supports up to 20 static route entries.
Dynamic Routing
With Dynamic Routing you can automatically adjust to physical changes in
the network's layout. The Router, using the RIP protocol, determines the net-
work packets’ route based on the fewest number of hops between the source
and the destination. The RIP protocol regularly broadcasts routing informa-
tion to other routers on the network. To set up Dynamic Routing:
1.
Choose the correct working mode.
Gateway Mode
should be used if the
Router is hosting your network's connection to the Internet.
Router Mode
should be selected if the Router exists on a network with other routers.
2. Choose the
protocol
by which you transmit data on the network.
3. Choose the
protocol
by which the Router receives network data.
4. Click the
Apply
button to save your changes.
