STUN (Simple Traversal of UDP (User Datagram Protocol) through NATs (Network Address
Translators)
is a network protocol allowing a client behind a NAT (or multiple NATs) to find out its public
address, the type of NAT it is behind and the internet side port associated by the NAT with a particular local
port. This information is used to set up UDP communication between two hosts that are both behind NAT
routers. The protocol is defined in RFC 3489.
