I believe so, though I am not familliar with the Linux implementations and I just started using NATd today (though I have been told that it works flawlessly with a number of protocals). > 2) This one is a bit lengthy, involves ASCII artwork, and is > network-general, though I hope it will apply to FreeBSD or any free > 'nix. > > 10BaseT Ethernet > > A (WinNT) > | > ADSL --- HUB --- B (Win95) > | > C (whatever) > > All the machines in this scenario pull IP off a DHCP server over the > ADSL. > > Transfers from any local machines, such as A sending a file to B > cause the ADSL modem to go nutzo.

Once again, I am only vaguely familliar with the concept so you should check www.freebsd.org for info.
