Hello! I was experimenting with the new High Performance screen sharing mode that Apple recently introduced to macOS Sonoma, which is supposed to (and, at least on LAN connections) reduces latency and increases quality by using the media engine in Apple Silicon Macs to accelerate screen sharing encode and decode.
According to Apple's documentation, this feature requires UDP ports 9000, 9001, and 9002 to be open, which I assume is available through the IKEv2 connection, since the connection succeeds and is able to authenticate to the remote Mac. However, as shown in the attachment below, no picture is displayed - there is only a mouse cursor. Clicks and mouse movements are still translated to the remote machine, but no picture is displayed.
I did quite a bit of research on this issue, and it seems that this issue is not due to a slow connection, since VM network bridges still result in the same issue. Indeed, it appears that this issue is quite widespread, and perhaps due to Apple's implementation of how High Performance Mode might only support local connections: [1], [2].
It is worth noting that someone suggested (but did not test themselves) High Performance mode via Tailscale. I have no clue if this works, and did not try, because Tailscale uses a different approach than a standard IKEv2 VPN like this container. Someone else on StackExchange said that WireGuard is able to perform High Performance, so perhaps it is possible (since Tailscale is based on WireGuard).
