I'm in the process of configuring a new ACID node and all is going...slowly. My immediate challenge is Echolink connectivity. When I connect to the Echolink Test Server, I hear the connect message, but I do not hear my audio return after transmitting.  I have double-checked port forwarding through my router (UDP 5198-5199 and TCP 5200). What am I overlooking?  Troubleshooting suggestions appreciated.
