What are TURN servers?

When you are conducting webrtc video conferencing or file tranfers between devices that are behind different NATs, it becomes difficult to connect then directly

As NAT provides a private IP address to clients that are behind the NAT and all the traffic is tunneled through a single Public IP address

Here TURN servers come in to play. They transfer the data from one client to another when direct connection is not possible because of NAT or firewall rules

Here one client sends the data to the TURN server and the TURN server sends the data to other clients that are doing webrtc video conferencing or file transfers etc
