Welcome to TurnServer project - open-source TURN server implementation.
This protocol allows a client to obtain IP addresses and ports from such a relay. It is most useful for elements behind symmetric NATs or firewalls that wish to be on the receiving end of a connection to a single peer.
The TurnServer project aims to be compliant with the TURN and STUN Request For Comments (respectively RFC 5766 and RFC 5389). It also support RFC6156 namely TURN-IPV6 (relay between IPv4-IPv6, IPv6-IPv4 and IPv6-IPv6 addresses) and RFC6062 namely TURN-TCP (relay data with TCP).
