Mohamed Boucadair, Reinaldo Penno, Dan Wing, Francis Dupont · 2011
This document specifies the behavior of the UPnP IGD (Internet Gateway Device)/PCP interworking function. An UPnP IGD-PCP Interworking function is required to be embedded in CP routers to allow for transparent NAT control in environments where UPnP is used in the LAN side and PCP in the external side of the CP router.
