Kevin, thank you. I am big fan of best practices and now I know this, I will have one Pi per interface. So now I have one Pi on my 220 repeater (that Pi also runs the hub node) and one Pi on my 440. They are both at my QTH behind my firewall/router. They can connect to “outside nodes” but not each other. Each have their own dedicated IP address on the LAN. Each are using the same server on port 4569. Do I need a separate server and port (4570?) for one of them or is there something else I am missing?
Thx again, 73, VE7NZ
