- Route Configuration

This sub menu is used to add static routes into the routing table. This feature is useful when there are
destinations that cannot be reached using the default gateway or when there are several subnets in
your local network. The interface can accept a network or host address to route. For example:
Network=192.168.22.0/24 can be reached through router 192.168.1.50, then:
Destination IP: 192.168.22.0
Mask: 255.255.255.0
Gateway: 192.168.1.50
Static route to host 192.168.22.5 through router 192.168.1.50 then:
Destination IP: 192.168.22.5
Mask: 255.255.255.255
Gateway: 192.168.1.50
