Traversal Using Relays around NAT (TURN) [RFC5766] is an extension to the Session Traversal Utilities for NAT [RFC5389] protocol. TURN allows for clients to communicate with a TURN server and ask it to allocate ports on one of its host interfaces, and then relay traffic between that port and the client itself. TURN, when used in concert with STUN and Interactive Connectivity Establishment (ICE) [RFC5245], forms a solution for NAT traversal for UDP-based media sessions.

Traversal Using Relays around NAT (TURN) Extensions for TCP Allocations
This specification defines an extension of Traversal Using Relays around NAT (TURN), a relay protocol for Network Address Translator (NAT) traversal. This extension allows a TURN client to request TCP allocations, and defines new requests and indications for the TURN server to open and accept TCP connections with the client's peers. TURN and this extension both purposefully restrict the ways in which the relayed address can be used. In particular, it prevents users from running general-purpose servers from ports obtained from the TURN server.
