The IESG has approved the following document: - 'Port Control Protocol (PCP)' (draft-ietf-pcp-base-29.txt) as Proposed Standard This document is the product of the Port Control Protocol Working Group. The IESG contact persons are Ralph Droms and Brian Haberman. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-pcp-base/ Technical Summary 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. Working Group Summary At the outset, the WG looked at many other protocols that have been proposed in the past for doing similar things, but almost none have been successful in getting real deployment. The exceptions are NAT-PMP and UPnP-IGD. Between them, the WG concluded that NAT-PMP was more closely aligned with the intended scenarios and hence used NAT-PMP as the starting point for PCP. Document Quality Several PCP implementations exist, and some interoperability testing has already been done. Margaret Wasserman did a thorough security analysis and wrote the security considerations section. Many others (beyond the authors themselves), including a number of implementers, have also done reviews and are acknowledged in the document. Personnel The Document Shepherd is Dave Thaler and the responsible Area Director is Ralph Droms.
