Static routes are designed for traffic that should not pass through the default gateway. It can also be used to add some routes to link units to other networks in your company.

Go to the "Routing" tab on the "Preferences" page. If static routes are required, they can be added to the routing table using the "ip route add" command. 

To add a static route to a host address, in other words to a single IP address, use a command:  ip route add via

To add a static route to a network, in other words to an IP address representing a range of IP addresses, use the following command:  ip route add via

Restart the unit for the changes to take effect. Each time the system starts, the specified commands apply. The log will show the set up new routes or errors if it occurs.
