Traversal Using Relay NAT (TURN)

Traversal Using Relay NAT (TURN) is a protocol, currently at the working draft stage, that is intended to govern the reception of data over a Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) connection by a single communications device operating behind a Network Address Translator (NAT) or firewall. A TURN server relays packets from an external Internet Protocol address (IP address) towards an internal device only if that internal device has previously sent a packet through the same TURN server to that particular external IP address.
