MacOS – Internet sharing over AirPort

airportinternet-sharingmacos

In MacOS X 10.6, is Internet sharing over AirPort implemented as NAT or full-blown routing? The backing wired network is a corporate one, Ethernet with DHCP.

Can't find anything definitive from Apple, but the detailed testing done here by Princeton University indicates that it's NAT (and that it's inappropriate for use on their campus, so might well be for your scenario too).
