What ports do I need open in my firewall

For just communication back to the TX server (like a cloud server set up) you only need port 40404 open.


If you are trying to communicate from your iOS and OS X devices back through the firewall as well then you also need:

1900 – UPD port

5350 – UPD port

5351– UPD port

5353– UPD port

9100 – TCP port

631 – windows airprint port

11631 – mac airprint port.
