Routes
Configuration | System | IP Routing | Default Gateways
This screen lets you configure the default gateway for IP routing, and configure the tunnel default
gateway for tunneled traffic. You use this same screen both to initially configure and to change default
gateways. You can also configure the default gateway on the Configuration | Quick | System Info screen.
The IP routing subsystem routes data packets first using learned routes, then static routes, then the
default gateway. If you don't specify a default gateway, the system drops packets it can't otherwise route.
For tunneled data, if the system doesn't know a destination address it tries to route the packet to the
tunnel default gateway first. If that route isn't configured, it uses the regular default gateway.

Default Gateway
Enter the IP address of the default gateway or router. Use dotted decimal notation; e.g.,
192.168.12.77
Concentrator interface. If you do not use a default gateway, enter 0.0.0.0 (the default entry).
To delete a configured default gateway, enter 0.0.0.0 .
The default gateway must be reachable from a VPN Concentrator interface, and it is usually on the public
network. The Manager displays a warning screen if you enter an IP address that is not on one of its
interface networks, and it displays a dialog box if you enter an IP address that is not on the public
network.
Metric
Enter the metric, or cost, for the route to the default gateway. Use a number from 1 to 16 , where 1 is the
lowest cost. The routing subsystem always tries to use the least costly route. For example, if this route
uses a low-speed line, you might assign a high metric so the system will use it only if all high-speed
routes are unavailable.
