From the Dynamic
Routing tab,
shown in Figure 5-
18, you can auto-
matically adjust to
physical changes
in the network’s
layout. The Router,
using the RIP pro-
tocol, determines
the network pack-
ets’ route based on
the fewest number
of hops between
the source and the
destination. The
RIP protocol regularly broadcasts routing information 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. In

the

TX field, choose the protocol by which you transmit data on the net-

work.

3. In

the

RX field, choose the protocol by which the Router receives network

data.

4. Click

the

Apply button to save your changes.

To view the Routing Table, which shows the network layout, click the Show
Routing Table button.

To clear any values you’ve entered on any page, click the Cancel button. To
apply any settings you’ve altered on any page, click the Apply button.

Advanced Tab: Dynamic Routing

Important:

Dynamic Routing is an Advanced Function. No

changes should be made to this tab without a thorough under-
standing of networking concepts.

Port Triggering

From the Port Range
Forwarding tab, shown
in Figure 5-17, click the
Port Triggering button
to allow the Router to
watch outgoing data for
specific port numbers.
The IP address of the
computer that sends the
matching data is
remembered by the
Router, so that when
the requested data
returns through the
Router, the data is
pulled back to the proper computer by way of IP address and port mapping
rules.

1. Enter

the

Application Name of the trigger.

2. Enter the Trigger Port Range used by the application. Check with the

Internet application for the port number needed.

3. Enter the Incoming Port Range used by the application. Check with the

Internet application for the port number needed.

4. Click the Apply button.
