Hi. Could I please get some insight into my problem from the gurus here. I am trying to configure our Clubs Echolink linked to our repeater. It is all set up in sysop mode with router ports open - echolink tests router and firewall ports as succeeded. All is working fine if the user connects via a PC but it times out if trying to connect via a smartphone -IOS and Android. Echolink connects fine via smartphone to other repeaters in my area via smartphone but refuses to connect to our clubs echolink. Our internet for Echolink is via a Mikrotik router. I suspect it may be a firewall issue but am at a loss as to why it allows a PC to connect and not a smartphone - Oh, and the PC and smartphone is using the same wireless access from a user perspective.
