Hi John,<br>
<br>
As Tim mentioned, you need to setup your NAT-firewall device as the WAN<br>
host on the DMZ, rather than the RasPi node. Then, selectively forward the<br>
ports needed from the NAT-firewall to the BBB and RasPi on its LAN side.<br>
<br>
For the RasPi:<br>
echolink requires two ports:<br>
Forward UDP ports 5198 and 5199 to the RasPi LAN IP.<br>
<br>
IRLP is more complex. All these ports go to the RasPi LAN IP:<br>
Forward UDP ports 2074 through 2093<br>
Forward: TCP ports 15425, 15426, 15427<br>
<br>
For the BBB, assuming you're using the default port:<br>
AllStar: Forward UDP port 4569 to the BBB LAN IP.<br>
<br>
That should do it, I think!<br>
<br>
