Technical Summary
Session Traversal Utilities for NAT (STUN) is a protocol that
serves as a tool for other protocols in dealing with Network
Address Translator (NAT) traversal. It can be used by an endpoint
to determine the IP address and port allocated to it by a NAT. It
can also be used to check connectivity between two endpoints, and
as a keep-alive protocol to maintain NAT bindings. STUN works with
many existing NATs, and does not require any special behavior from
them.
STUN is not a NAT traversal solution by itself. Rather, it is a
tool to be used in the context of a NAT traversal solution.
In keeping with its tool nature, this specification defines an
extensible packet format, defines operation over several transport
protocols, and provides for two forms of authentication.
This document obsoletes the original STUN specification RFC 5389.
