Ubuntu Linux Add Static Route

To add a static route to the network configuration on an Ubuntu Linux system, you can use the route command.

To add a static route, you will need to specify the destination network, the gateway to use for the route, and the network interface that the route should be associated with. For example, to add a static route to the 192.168.1.0/24 network via the gateway 192.168.0.1 on the eth0 interface, you can use the following command:

sudo route add -net 192.168.1.0/24 gw 192.168.0.1 dev eth0

This will add the static route to the system's routing table.

To make the static route persist across reboots, you can add the route to the /etc/network/interfaces file. For example, to add the above route to the eth0 interface configuration, you can add the following lines to the /etc/network/interfaces file:

up route add -net 192.168.1.0/24 gw 192.168.0.1 dev eth0
down route del -net 192.168.1.0/24 gw 192.168.0.1 dev eth0

This will cause the route to be added when the eth0 interface is brought up, and removed when the interface is brought down.

Keep in mind that the above steps assume that you are using the /etc/network/interfaces file to configure the network interfaces. If you are using a different method to configure the network, the steps may be different.

For more information on configuring static routes on Ubuntu Linux, you can refer to the route man page or the Ubuntu documentation.
