Firewall rules (Ubuntu)

Hi guys

I want to configure the ufw firewall on my Ubuntu server but without it interfering with the channels dvr service running on it.

Is it only 8089 tcp inbound that the dvr server uses for all it's functionality? Or is it more complicated with the tuners/bonjour/client apps involved?

Regards

8089 tcp and 5353 udp

Excellent, thank you!
