If you have an up to date /etc enabling IPNAT in rc.conf automatically sets up
ipf for you. So it does not really need a man page entry. Although I can see
that while experimenting before enabling it for real it would be useful to
know as I have also spent significant time wondering why it did not work.

This I would definitely support. It was only by scanning back through large
amounts of current-users mail that I managed to find the options required.
