I think the best answer is 'man route' route add -net 192.168.2.1 netmask 255.255.255.0 dev eth1 route add -net 192.168.1.1 netmask 255.255.255.0 dev eth0
A good friend once described the best way to understand routing: "be the packet". If your .1.x clients are trying to get to .2.1, and their gw is .1.1, .1.1 needs to know _where_ .2.x is. You tell it that in the first route statement above. The inverse is true, .2.x clients (and responses from the .1.x pings, etc) need to know where .1.x is, hence the second statment. I imagine that you also will have a 'default' setup for all other traffic going to the net? I assumed your netmasks above to be /24, replace with whatever it really is, likewise for the eth naming. Make sure that whatever eth device each network is on is listed correctly. (in other words if 192.168.1.1 is bound to eth0 and 192.168.2.1 is bound to eth1 the above is correct).
