I’ve been using ZT on a bunch of nodes, including my mobile devices, with great success. Mostly to access various solar installations and control different systems remotely.
Recently, I configured the client on my mother’s iMac so I could use native screen sharing instead of TeamViewer, which works well.
This appears to have broken FaceTime, I assume because the systems can now see each other over Bonjour/Zeroconf. But whatever logic Apple uses isn’t working completely enough to get the RTP streams to he right places.
Is there a fix? Maybe disable multicast to that node?
