Router Application
The second basic application for the RASFinder is LAN-to-LAN routing as shown in Figure 4-3. The
RASFinder is initially configured for a RAS application. To configure the RASFinder for a router
application, you have to change the WAN port addresses to be on a different network from the LAN
port. The remote WAN ports have to be on the same network as the local WAN ports. Finally, you
would have to change the Remote Port setup from a RAS application (Client only) to a routing
application (Client or LAN). If your routing application would benefit from having all three WAN ports
tied together to triple your WAN speed, then you would have to enable the MultiLink Point-to-Point
protocol (MLPPP) option.
Figure 4-3. Router Application
During initial software loading, you begin to configure the RASFinder for a routing application. A
typical routing application is shown in Figure 4-3 and will be used as an example in the following
discussion.
When you changed your LAN IP address in the Default Parameters dialog box to your unique LAN
addressing structure and then try to change your Remote WAN port addresses to a different network
which you need for your routing application, you set up RAS as the default configuration versus your
router configuration. The Default Parameters dialog box will not allow you to change the addressing
scheme of the Remote WAN ports to your unique addressing structure for your routing application.
Therefore, you have to leave the Default Parameters dialog box set up for a RAS application initially
(during initial software installation and configuration); then later, from the main menu, you can switch
