Description of Issue
My Roon Core runs on a Mac Mini with a static IP and my Comcast router is configured to port forward the ARC listen port to the Mac Mini and has UPnP enabled. Unfortunately, the Comcast router apparently has a bug that forces you to include the static IP address of the Roon Core server in the DHCP range when creating the port forward rule. At this point, I was able to successfully configure and test Roon ARC. I then reconfigured the Comcast router DHCP to exclude the static address of the Roon Core server. After I did this, Roon ARC stopped working on all my devices. Reverting the Comcast router DHCP settings fixes the problem. Why is this? Why would the DHCP configuration influence Roon ARC?
