I've been working on a similar setup only with with two ethernet cards,
one for the lan and the other for internet access.  The problem I've been
having is that when I attempt to specify the device I get an error:
"SIOCADDRT: Invalid argument" when I load the commandline

route add -net [local net address] dev eth0

or

route add -net [wan address] dev eth1

Both interfaces recieve correctly but all outbound is going through the
latter (eth1) interface.  I'd love to know how to get this to work
correctly.
