Thanks for the help.  It works pretty quite well, even on the old server I
am using.  TCP and UDP traffic gets through okay, but pings and traceroutes
don't work.  I guess that is an extra field I have to add to
/etc/ipnat.conf, or is it even supported by ipnat.  Oh well, Its not that
important.  I'll re-read the man pages later.

It was this kind of thinking that caused the problem in the first place.
