Description

I'm currently running a private server with a few minecraft instances on it. We have tried a few times to get the Simple Voice Chat (and Audioplayer) mod working, however it requires an extra port (24454/udp in this case).

Is there a way to pass through this extra port? I even tried directly exposing the minecraft docker port and pointing the mod client at the server's ip address (though this would mean multiple instances would need different ports hard coded) but no luck.

If this isn't currently possible on mc-router, is it possible to add this support?

Cheers

Research direction

Start by inspecting mc-router's current connection-routing and Docker port configuration, then reproduce the Simple Voice Chat case using UDP port 24454 across multiple Minecraft instances. Determine whether the requested mapping can avoid conflicting hard-coded ports; done means configurable UDP forwarding works for each instance.
