could send a document to the corporate printer.
This static route is shown in the top network in Figure 4-4. A static route can also use an
unnumbered link to provide a particular route for a remote server to appear as a server on the
corporate network. The unnumbered link is shown in the middle network in Figure 4-4.
Figure 4-4. Static Routes
In our first example above, where a data packet from the remote client PC on the manufacturing
network is being sent to the corporate printer, a static route would be established on the corporate
RASFinder to have WAN 1 and WAN 2 with network address of 200.2.10.1 and a gateway address of
200.2.10.2, the remote network. The Static Routes Setup dialog box would contain the address of
200.1.1.0 in the IP Address field and a gateway address of 200.2.10.2. The Unnumbered option
would be left unchecked in this example. The IP Address field contains the address of the target host
or network, a PC on the manufacturing network. The Gateway Address is the address of the local
router on the manufacturing network (200.2.10.2) on the next hop toward the target host. The
Address Mask is the IP subnetwork mask (255.255.255.0) of the target host. The Port field is
inactive, greyed out in this example.
This example establishes a static (direct) path for the user on the client pc on the manufacturing
network to send a letter to the corporate LAN and have it printed on the corporate network printer.
The control for this static path is the RASFinder on the corporate LAN.
Now, for our second example of an unnumbered link where we want a server on a remote network to
appear as a device on the corporate LAN. Lets use the example of the Internet router on the
corporate network wanting to provide manuals from the Publications network to Internet users. Lets
say that the Manuals Server on the Publications Network contains released manuals that a customer
can down load from the corporate network. So in order to have the Manuals Server appear on the
Internet router, we need to set up the corporate RASFinder with an unnumbered link and for the
purposes of our example, lets use the middle two WAN ports (WAN 3 and WAN 4). Also, the
Internet router will have a default route of 192.168.2.224 with a subnet Address Mask of
255.255.255.224, and a Gateway Address of 192.168.2.10. The Manuals server would need a
gateway pointing to the corporate RASFinder. The gateway address on the Manuals server could be
192.168.2.225.
