Has PF even been > fully implemented into the 5.x series? Yes. The 5.3-RELEASE version was the first official release of FreeBSD that included PF as part of the base system. As far as the original question, regarding PF and forwarding, the answer is AFAIK, that it should work. I haven't used PF's network address translation until now, but I don't see why it wouldn't work. Packet forwarding is, unless I'm mistaken, a prerequisite for any gateway. The fact that the gateway also translates addresses is not obligatory but just a characteristics of the local network topology (i.e. availability of public addresses).
