One RTCPeerConnection to local TURN server to local TCP/UDP server back to single Data Channel?

[guest271314]

If I'm reading this https://datatracker.ietf.org/doc/html/rfc5766 and this https://datatracker.ietf.org/doc/html/rfc6062 correctly, it's possible to connect to a *local* TURN server (TCP socket) with something like this alone https://webrtc.org/getting-started/turn-server

```
const iceConfiguration = {
    iceServers: [
        {
            urls: 'turn:my-turn-server.mycompany.com:19403',
            username: 'optional-username',
            credential: 'auth-token'
        }
    ]
}

const peerConnection = new RTCPeerConnection(iceConfiguration);
```

and thereafter communicate directly with a local TCP or UDP socket, that can be sent back to WebRTC Data Channels https://datatracker.ietf.org/doc/html/rfc8831, negating the need for a second `RTCPeerConnection` to communicate directly with a local TCP or UDP socket through a local TURN server relay?

The question is not very clear. WebRTC doesn't support RFC6062. 

If the local TURN server means  TURN server running on the local IP address without external mapping then It has no practical use cases, especially in real-world WebRTC deployments.

Basically, connect a local RTCPeerConnection directly to a local TCP
or UDP server.

Got it. This should work. This doesn't need RFC6062. Need to configure and install TURN server properly. 

Thanks,

There's the rub.

I'm trying to use TCPServerSocket in Chrome browser itself as the TURN
server. So the TURN server will be written in JavaScript or compiled
to WebAssembly.

What are the basic connection parameters?
