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.

RFC 6970 UPnP IGD-PCP IWF July 2013
1. 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 function
