You can put these into a script and call it from /etc/rc.local #!/bin/bash # Script may be called from rc.local # FIrst off use the following to add an address to the device (say eth0). ip address add 192.168.0.1 dev eth1 # Now add a route if you need it. ip ro add 192.168.1.0/24 via 192.168.0.1 dev eth0 # end script # ------------------------------------------------------------ # Make sure you allow packets to be forwarded # ie this will now route between the 2 networks # Add this line to /etc/sysctl.conf net.ipv4.ip_forward = 1 # To have above take effect without a reboot do sysctl -p g/
