An IP :address is bound to a network. So if you're on a different network, :you get a different IP address. Why do you need the same Ethernet :address? You need a switch to do this. If your clients are on the same ethernet as your server, they can only talk to one MAC address. That means you only get the bandwidth of one interface. If you have a switch that can bond ports together, you can use both cards at the same time, transparently to everybody but the driver and the switch. I know that NetWare supports this, as do some Bay switch, and surely some Cisco stuff.
