A new Request for Comments is now available in online RFC libraries. RFC 7652 Title: Port Control Protocol (PCP) Authentication Mechanism Author: M. Cullen, S. Hartman, D. Zhang, T. Reddy Status: Standards Track Stream: IETF Date: September 2015 Mailbox: margaret@painless-security.com, hartmans@painless-security.com, zhang_dacheng@hotmail.com, tireddy@cisco.com Pages: 34 Characters: 78237 Updates: RFC 6887 I-D Tag: draft-ietf-pcp-authentication-14.txt URL: https://www.rfc-editor.org/info/rfc7652 DOI: http://dx.doi.org/10.17487/RFC7652 An IPv4 or IPv6 host can use the Port Control Protocol (PCP) to flexibly manage the IP address-mapping and port-mapping information on Network Address Translators (NATs) or firewalls to facilitate communication with remote hosts. However, the uncontrolled generation or deletion of IP address mappings on such network devices may cause security risks and should be avoided. In some cases, the client may need to prove that it is authorized to modify, create, or delete PCP mappings. This document describes an in-band authentication mechanism for PCP that can be used in those cases. The Extensible Authentication Protocol (EAP) is used to perform authentication between PCP devices. This document updates RFC 6887. This document is a product of the Port Control Protocol Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements.
