Here's a nice step-by-step: <http://www.swcp.com/~synk/ipf-howto.txt>.
The "IP Filter Home Page",
<http://coombs.anu.edu.au/~avalon/ip-filter.html>, has more links, but
not NetBSD-specific. There are examples in /usr/share/examples/ipf,
and three each ipf and ipnat man pages, "man -a ipf ipnat". Also,
don't overlook the mailist list archives, especially
<http://www.netbsd.org/MailingLists/index.html#netbsd-help>.
