Traversal Using Relay NAT (TURN) is a protocol that allows for an element
behind a NAT or firewall to receive incoming data over TCP or UDP
connections. 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. TURN does not allow for users to run servers on well known ports if
they are behind a nat; it supports the connection of a user behind a nat to
only a single peer. In that regard, its role is to provide the same
security functions provided by symmetric NATs and firewalls, but to "turn"
them into port-restricted NATs.
