Defining the Default Gateway (Optional)

Default routes or default gateways are used to forward packets addressed to unknown networks to avoid having to discard the packet. The not-too-practical alternative is that all routers, firewalls, and VPN devices would have to know all the routes in the world.

The default route for the Concentrator to which you forward all outside bound packets can be defined either by choosing the Default Gateway link on the Configuration | Interfaces screen or by using the Configuration | System | IP Routing | Default Gateways menu to add these special forms of static routes. Figure 14-14 shows the resulting screen with the appropriate entries to use Rtr1 as the default gateway for the network.

In the example scenario, if no additional routers are in the LAN, the PCs in the LAN would use the Concentrator private address for their default gateways.
