Re: Doing nat only with <ONE> nic

[Chuck Yerkes <chuck+obsd_(_at_)_2002_(_dot_)_snew_(_dot_)_com>]

The 2 simple things that jump to my mind:
1) get another NIC - a decent one, not a US$15 special.
2) for simple home use for a person who doesn't really "do" Unix,
   get a dedicated NAT box/DSL router instead.  Quiet, simple to
   configure, unlikely to die like an old machine, and YOU don't
   have to maintain it.  You get a reasonable protection via
   NAT if you keep it from mapping new connections back.

If/when that "old machine" dies and he has no internet access
for weeks, he will dislike Unix more.
