Simple Traversal of User Datagram Protocol (UDP) Through Network
Address Translators (NATs) (STUN) is a lightweight protocol that
allows applications to discover the presence and types of NATs and
firewalls between them and the public Internet. It also provides the
ability for applications to determine the public Internet Protocol
(IP) addresses allocated to them by the NAT. STUN works with many
existing NATs, and does not require any special behavior from them.
As a result, it allows a wide variety of applications to work through
existing NAT infrastructure.
This document is a product of the Middlebox Communication Working
Group of the IETF.
This is now a Proposed Standard Protocol.
This document specifies an Internet standards track protocol for
the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the
"Internet Official Protocol Standards" (STD 1) for the
standardization state and status of this protocol. Distribution
of this memo is unlimited.
