Some security devices also enable you to configure a route entry based on the source IP
address of the data packet.
To create a static route for a network destination, you must enter the IP address and
netmask for the destination network, then select the interface through which the next
hop router is accessed. You must also enter the IP address of the next hop router and
configure a metric for the route.
For instructions for configuring virtual router source-based route entries, see the Network
and Security Manager Online Help.

In this example, you want to forward traffic from the 10.1.1.0/24 subnetwork to ISP 1, and
forward traffic from the 10.1.2.0/24 subnetwork to ISP 2. You must configure two entries
in the default trust-vr routing table and enable source-based routing. The subnetwork
10.1.1.0/24, with ethernet1 as the forwarding interface, uses the ISP 1 router (1.1.1.1) as the
next hop; subnetwork 10.1.2.0/24, with ethernet2 as the forwarding interface, uses the
ISP 2 router (2.2.2.2) as the next hop.
In the NSM navigation tree, select Device Manager > Devices. Double-click the device

In the device navigation tree, select Network > Virtual Routers. Double-click the

trust-vr virtual router. The General Properties screen appears.
