Looking at CLI of the asterisk behing NAT, do you see anything trying
to authenticate when you call from another box? How would the asterisk
behind NAT ever know anyone was calling it without forwarding port
4569 to it (or at least allowing traffic inside on it)? One of the
boxes has  to begin a dialogue, and that would be the one behind NAT.
I'm not betting my life on the above, it's just a free opinion which
I'm sure 10,000 people will jump in and correct if necessary.
