My asterisk server (pbx) registers through my NAT without ANY rules or 
what have you.  I do have the NAT
option turned on for the 4 providers I connect to.

That said, sipoxd/pfSense may work as well.  I do go through pfSense, 
but again do NOT have any SUP proxying.  The asterisk server just keeps 
a registration open.

I can get and receive calls.

FWIW
