ok...here is what i want to do and i believe its possible with NAT but i just dont know how to set it up.

the setup:

i have a home network with a cable modem, router, hub, and WAP.

on a normal software basestation, your "external" network comes from the ethernet and your "internal" network goes out through airport....

what i want is a way to have my "external" network to come from airport via the WAP, and my "internal" network to go out through the ethernet. this is effect would make my ibook a bridge. i could just plug a crossover cable into another machine and that maching would be on the network....

any ideas as to how to accomplish this? this would eliminate the need for wires laying all around the house...

thanks
