NAT Behavior Discovery Using Session Traversal Utilities for NAT
RFC 5780, “NAT Behavior Discovery Using Session Traversal Utilities for NAT”, is an Experimental document published in May 2010 by D. MacDonald, B. Lowekamp. It has since been updated by RFC 8553. The canonical text is published by the RFC Editor.
Abstract
This specification defines an experimental usage of the Session Traversal Utilities for NAT (STUN) Protocol that discovers the presence and current behavior of NATs and firewalls between the STUN client and the STUN server. This document defines an Experimental Protocol for the Internet community.
What “Experimental” means
Describes a specification that is part of a research or development effort, published so the community can gain experience with it.
