In a similar situation at my place of work, there is a machine set up with two NICs, one to access a 'private' LAN with a DB server on it and one for general customer access. In that case, we have the customer LAN set as the default card with the default gateway. With the other, we have added a route which specifies the second CARD - NOT a gateway address on that second LAN. I believe you have to tell the box which card to use for that 'private' LAN and not which gateway. If you just specify a gateway address then it will look for this address via the default NIC/gateway. It has to be an address it has knowledge of. I.e. the second NIC's IP address.

Hope this helps
