Well...  Not just addresses.  Since the reason for NAT is that there
are too few "real" addresses in the first place, it also of necessity
changes port numbers to create the many-to-few relationship.

This sounds utterly reasonable to me.  I've had my share of troubles
because of such misdesign, for instance in trying to get Kerberos to
work right on machines with several IP interfaces.
