Manuel,

This is very interesting.  You say that ipfilter needs to be enabled for NAT
to work.  The rest of my ipnat.conf file is working just fine.  I have a
number of computers behind the NetBSD machine and they CALL are able to access
the Internet thanks to the first three lines of the ipnat.conf file.  But all
the same I took your word for it and created a basic ipf.conf that simply has:

pass in from any to any

I set ipfilter=Yes in the /etc/rc.conf and rebooted.  When I ssh from the
outside, I still end up on the NetBSD machine (future firewall).  Any more
thoughts on what I can try?
