We've had 'ipfw2' for a very long while.  I couldn't help wondering why 
DF wouldn't just import our many years of development and experience 
rather than using bycn82's 'rewrite'? .. but DF already has ipfw2:

http://leaf.dragonflybsd.org/cgi/web-man?command=ipfw&section=ANY

man page dated October 2008.  Before tables, in-kernel NAT, later 
dummynet updates and no doubt more.  So why not start from there?

cheers, Ian
