Persistent static routes

I wanted to direct traffic to the network 192.168.1 via 192.168.0.200 rather than via the default gateway and this is how I did it. It is kind of basic, but it varies between platforms.

In Windows it is very easy, simply run:


route -p add 192.168.1.0 mask 255.255.255.0 192.168.0.200 metric 10

The route is added immediately and will survive restarts.

For Red Hat Linux, CentOS and their relatives, create a file in /etc/sysconfig/network-scripts named route-ethX where X is the interface number. In my case I created the file /etc/sysconfig/network-scripts/route-eth0. The file should contain:


GATEWAY-N=xxx.xxx.xxx.xxx
NETMASK-N=yyy.yyy.yyy.yyy
ADDRESS-N=zzz.zzz.zzz.zzz

where N is the route number. In my example:


GATEWAY0=192.168.0.200
NETMASK0=255.255.255.0
ADDRESS0=192.168.1.0

Finally for Ubuntu and other Debian-related Linux versions, modify the file /etc/network/interfaces and add an up command. In my case I added:


up route add -net 192.168.1.0 netmask 255.255.255.0 gw 192.168.0.200 eth0

Including the other lines for eth0 this resulted in:


iface eth0 inet static
address 192.168.0.20
netmask 255.255.255.0
gateway 192.168.0.1
up route add -net 192.168.1.0 netmask 255.255.255.0 gw 192.168.0.200 eth0
auto eth0
