Debian linux Routing configuration

In Debian linux, i need to add some IP specific routing config. I have a default route for internet, and have other gateway for other services to access.

So i need to be able make the routing configuration is injected when the network services loaded.

How to do this are, in your /etc/network/interfaces add this :

auto eth0

iface eth0 inet static
  hwaddress 00:1b:24:b0:b7:8f
  address 192.168.113.109
  netmask 255.255.255.0
  broadcast 192.168.113.255
  gateway 192.168.113.224
  up route add -net 172.16.0.0 netmask 255.255.0.0 gw 192.168.113.204
  up route add -net 172.30.0.0 netmask 255.255.0.0 gw 192.168.113.205
  up route add -net 192.168.0.0 netmask 255.255.0.0 gw 192.168.113.206
  up route add -net 10.0.0.0 netmask 255.255.0.0 gw 192.168.113.104



So the result are like this :

Default traffic going to 192.168.113.224 , and traffic going to network 172.16.x.x going through gateway 192.168.113.204 , and same rule apply to the next network destination.

You can add more route according your needs.
