Dear NetBSDers,
   It seems that the current implementation on NetBSD (well 1.2D) of ipnat
requires at least 2 bit net mask (as stated in the manual for dealing with
broadcast and network ip).
   However, it also seems that there are many situations where a ISP
provides only one IP and one would like to have a small lan behind the
machine running ipnat - for example a home lan or lan in a dorm suit. 
   Are there major issues in modifying ipnat to deal with one IP on one
side and a lan local IP (10.0.0.0) on the other side?  I understand that
broadcast might be a problem.  Has this been done already?  Any idea of
how hard it would be to do?
