What exactly is it you want to achieve? Fail-over? Load balancing? Increased uplink speed? And where doe these other two networks go? What's in the cloud on the right? –  wolfgangsz Jun 20 '11 at 13:58
    
fail over and increase speed, yes, in left its Internet cloud. –  haw3d Jun 20 '11 at 14:00

For a simple fail-over configuration you'll need two default routes with different metrics on the linux box. The one with the lower metric is the normal default gateway, the other one kicks in if the normal default gateway is down.

Speed increase cannot be achieved this way. For this you would need to trunk the connections, but since they reach into different networks, that is not possible.

Plus: The cloud on the right cannot be the public Internet. Addresses in the 192.168.x.y range cannot be routed on the public Internet. So what is it?
