[arm-allstar] Still struggleing with NAT

As mentioned in my previous message I can no longer stay connected when
transmitting to nodes outside my network.
With the 5268AC in DMZ and my router receiving the public address most
everything works other than allstar.
My Freepbx works just fine for both inbound and outbound SIP calls.
That version of Asterisk has a configuration option that lets you set if you
are using a NAT along with the info on the LAN being used.
It seems to be just fine.
If I switch to port forwarding and use the firewall and forwarding from the
5268AC to my router then Freepbx doesn't handle inbound calls.
The techs at my VOIP supplier say the packets are showing double NAT and
that is preventing inbound calls.
There must be something associated with my IAX2 packets since I can easily
connect to other nodes.
I can listen forever but only transmit for about 5 seconds before the
outbound TX quits.
The next transmit attempt causes the node to try and reconnect but after a
minute or so I get a node disconnected message.
This might not be strictly a Allstar issue but if NAT options make other
Asterisk installations function maybe there is something in the version we
run that I am overlooking.
If nothing else I'd sure like to know what is in the packets that is causing
the TX to barf.
tnx
