When webrtc connect to STUN, if the public IP's port returned by the STUN is the same as the port that is webrtc create socket with STUN used?

I find when the webrtc create socket with STUN , the port return by STUN always same as the socket port. Is it accidental or fixed?

It's called port preservation in NAT terminology. Port numbers are preserved unless there is a conflict which happens when you have more than one machine behind NAT accessing the same service.

This depends on the type of NAT you're behind, some NATs may translate the port as well.
