I am running a defederated local Matrix server, and I need to set up calls. From what I can tell, the “legacy” calls require a STUN and TURN server, and the new MatrixRTC standard seems to require them as well for Livekit to work. However, I do not want to expose anything out to the public internet, as I want everything to be behind NAT for local access only (all of the clients for the server will also be behind the NATted network). I also have Tailscale running on my servers, and it would be useful if I would be able to connect to the TURN server even when not in the network. Is there a way to get STUN/TURN to work in this situation? It seems that all the servers expect to have public network access.
I’m not qualified enough to answer that, but…
I tried setting up calls and while STUN/TURN works in WAN, but not LAN, Element are supposed to be making a replacement that makes voice and video calls entirely E2EE, aka Livekit, which I’ve completely failed to get working. So far I’ve given up on improving my instance’s features and stick to Element Classic. I hope you get it running well!
I’m in the same situation, I can do “legacy” calls almost without issues, but Livekit has constant issues connecting to TURN.
