I've got a iBook with airport and I want to use it like a ethernet wireless brigde to connect other computer to my home network. I already have a router and the wireless access point, and i'm already on a private network so I don't need and don't want to run thru a second NAT. So I wan't to know if there is any possibility with IPFW to only foward packet from the Aiport adaptor to the ethernet without going thru a NAT and passing all the ARP correctly.
