Port Control Protocol
RFC 6887, “Port Control Protocol”, is a Proposed Standard document published in April 2013 by D. Wing, S. Cheshire, M. Boucadair, R. Penno, P. Selkirk. It has since been updated by RFC 7488, RFC 7652, RFC 7843. The canonical text is published by the RFC Editor.
Abstract
The Port Control Protocol allows an IPv6 or IPv4 host to control how incoming IPv6 or IPv4 packets are translated and forwarded by a Network Address Translator (NAT) or simple firewall, and also allows a host to optimize its outgoing NAT keepalive messages.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
