Vanadium forbids direct UDP for WebRTC, and mobile and company networks often
block direct connections; the only route then is a relay reached over TCP.

  • server/turn.ts: STUN and TURN on one port, over UDP and TCP, with
    short-lived credentials from /api/turn, quotas and a peer filter
  • The browser build fetches credentials and offers the relay automatically
  • Stats for nerds says when a stream is relayed and how the relay is reached
  • Tests: a TURN client over UDP and TCP, and a browser limited to the relay
    over TCP in the web E2E
