Providing two channel at one TURN server

[Wonchul Shin]

Is there any way to have two channels at one TURN server?

I want to provide one more channel like as one UDP only(typically supported on TURN server) and one more TCP only.

I want to know how to provide one more channel for scalability.

It will be used for client control on NAT environment.

Have I set-up one more TURN server?

One more thing,

As I know, two ports are needed for RTP and RTCP.

TCP relay is used on some network such as UDP blocked environment.

I have set it to 443 port. it means RTP packet is relayed on TCP 443 port.

How about RTCP?

In this case it have to use multiplexing port?

A single TURN client can create many channels over the same protocol.

If you need channels of different protocols (UDP and TCP) then you have to create separate TURN sessions for them.

"RTP / RTCP even port" TURN feature allows two consecutive relay ports.

I'd advise reading the TURN specs (search for RFC 5766) for better understanding how the TURN works.
