Technical Summary
 
  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.
 
Working Group Summary

  There was a strong consensus in the WG to publish this document.
 
Document Quality

  This is a revision and change of scope of the STUN protocol. Thus it
  benefits from a number of implementation experiences with RFC 3489. It
  has been well reviewed by the WG participants.
