Default Route

The simplest option is to configure a default static route to send all traffic to an upstream router, relying on the router to route the traffic for you. A default route identifies the gateway IP address to which the threat defense device sends all IP packets for which it does not have a learned or static route. A default static route is simply a static route with 0.0.0.0/0 (IPv4) or ::/0 (IPv6) as the destination IP address.

You should always define a default route.

The threat defense has separate routing tables for data interfaces and for management-only interfaces (including the special Linux Management interface). You can only add a default route for the data routing table. The threat defense automatically adds a default route in the management-only routing table that sends traffic to the Linux Management interface, where a separate route lookup occurs in the Linux routing table. You can add static routes to the Linux routing table that can be used by Management using the threat defense CLI configure network static-routes command.

Note	The default Linux route is set with the configure network ipv4 or configure network ipv6 command.
