that port, particularly with UDP (with TCP, it could  figure out that it
can't bind to the port, but with UDP being  stateless, it might not know
there's another process also using the  port...?)

You are either worrying too much, or grasping at straws to try to explain a problem you're seeing but not telling us about. There is not a "NAT server" process; packet forwarding and address translation are done in the network stack. The right thing happens, unless you've tried hard to break it.

If you're seeing some actual problem and trying to figure out what's causing it, I suggest describing the problem to the list, rather than asking if your guess is right.
