Network Address Translation Behavioral Requirements for Unicast UDP
RFC 4787, “Network Address Translation Behavioral Requirements for Unicast UDP”, is a Best Current Practice document published in January 2007 by F. Audet, C. Jennings. It has since been updated by RFC 6888, RFC 7857. The canonical text is published by the RFC Editor.
Abstract
This document defines basic terminology for describing different types of Network Address Translation (NAT) behavior when handling Unicast UDP and also defines a set of requirements that would allow many applications, such as multimedia communications or online gaming, to work consistently. Developing NATs that meet this set of requirements will greatly increase the likelihood that these applications will function properly. This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.
What “Best Current Practice” means
Documents the IETF community's recommended operational or procedural practice rather than a protocol specification.
