It doesn't but with a two libs it could be made to do so.  Their are  
two libs to do both uPNP and PMP with little trouble.

That would allow you to create a module to subscribe to events to make  
them map the ports back to the FreeSWITCH box.  So mod_sofia could  
fire an event saying "Hey, I'm on port 5060" and your mod_nat could  
listen to those and poke the holes back to FreeSWITCH on those ports.   
Just an idea :)  I have thought about it before.
