I don't understand your question.

I'm tring to solve the more general case as possible.
Moreover, I'm tring to solve hairpin problems for UAs behind the same 
NAT (and only one).

All of this without proxing the RTP streams (just a couple of packets).

But the various kinds of "cone NATs" should allocate always the same 
port (for the same internal IP/Port). This is the assumption on which 
STUN is based!
