You'll need to run ethereal or another packet sniffer on the network
to see what is happening.

In general if your asterisk is going to _register_ (or qualify)
your external IAX provider you don't need to port-forward 4569,
the registration will setup a suitable nat/port mapping
and the qualify (or re-register) will keep it alive.
(But that isn't your problem....)
