Yes![1] If you really want to do just NAT without any sort of firewalling, it's still wrong, just use one NIC and use a virtual interface (this is what I've been doing until my broke ass gets a paycheck with enough left over after the important stuff (rent, food, bandwidth) that I have money to throw around for less important stuff (gas for the car, random hardware). You will need to have the appropriate kernel options set to have virutal interfaces (eth0, eth0:1). > Basically, you could be running 2 different subnets > on one network segment.
