I also have ipnat, but for pure port forwarding, I recommend "portfwd". It
is not in pkgsrc as far as I know, but it's really easy to use and can
even forward to other hosts if desired.

So for me it forwards local port ... hm ... 6222 to remote 6220 or so, i
can run a vncview across NAT with this nice tool...

Search in the net, it's easy to find.
