turned

Traversal Using Relays around NAT (TURN) is a protocol that assists in traversal of network address translators (NAT) or firewalls for multimedia applications. It may be used with the Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). It is most useful for clients on networks masqueraded by symmetric NAT devices. TURN does not aid in running servers on well known ports in the private network through a NAT; it supports the connection of a user behind a NAT to only a single peer, as in telephony, for example.

Turn may refer to:

• Turn (dance and gymnastics), rotation of the body
• Turn (swimming), reversing direction at the end of a pool
• Turn (professional wrestling), a transition between face and heel
• Turn, a quality of spin bowling in cricket
