You can try:

route add -net -n 192.168.0.0 netmask 255.255.255.0 dev eth0
route add -net -n 10.19.44.0 netmask 255.255.255.0 dev eth1
route add -net default gw 10.19.44.1

Thanks dimis! It works:d ah! thanks again.

btw, could you plz describe it a little..i mean i had configured it with netconfig, the gateway and all. but it didnt work.

dimis · 05-23-2006, 08:48 AM

It should work with netconfig maybe you just missed something there, i always hated these automated tools so i just prefer giving the commands myself.

here you're just adding static routes, specifying a network for every NIC you use and adding a default gateway for both NIC's unless other specified.

What you should check is if it works after reboot, if it doesn't you can just add these lines to your startup script

For Slackware for example is /etc/rc.local
