Use policy routes to control the routing of packets through the ZyWALL's
interfaces, trunks, and send traffic through VPN connections. You also use policy
routes for bandwidth management (out of the ZyWALL), port triggering, and
general NAT on the source address. You have to set up the criteria, next-hops,
and NAT settings in other screens first.
