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
there are two major TURN server providers and we are going to consider both.
these are
