Internet Engineering Task Force (IETF) M. Boucadair Request for Comments: 6970 France Telecom Category: Standards Track R. Penno ISSN: 2070-1721 D. Wing Cisco July 2013 Universal Plug and Play (UPnP) Internet Gateway Device - Port Control Protocol Interworking Function (IGD-PCP IWF) Abstract This document specifies the behavior of the Universal Plug and Play (UPnP) Internet Gateway Device - Port Control Protocol Interworking Function (IGD-PCP IWF). A UPnP IGD-PCP IWF is required to be embedded in Customer Premises (CP) routers to allow for transparent NAT control in environments where a UPnP IGD is used on the LAN side and PCP is used on the external side of the CP router.

Introduction The Port Control Protocol (PCP) specification [RFC6887] discusses the implementation of NAT control features that rely upon Carrier Grade NAT devices such as a Dual-Stack Lite (DS-Lite) Address Family Transition Router (AFTR) [RFC6333] or NAT64 [RFC6146]. In environments where a Universal Plug and Play Internet Gateway Device (UPnP IGD) is used in the local network, an interworking functionShow full document text
