I won't presume to say you're wrong, but I've done natd on a single interface in three different setups, and they run perfectly. Of course you would want to make sure your router, modem, dsl device, etc wasn't going to accept any non-routable IP packets, especially if you're using IP based security like in Samba. > There are other problems with this scheme.
