Also IP based access would be the lowest possible form of security. Anyone can defeat that with an off the shelf linksys (or whatever brand) device.

I wanted to know the kernel module or setting that would allow 2 nics on the same subnet. (it was changed in i believe 2.2.x and up.) As this would allow the card not to be a bottleneck in traffic.
