This device template is compliant with the UPnP Device Architecture, Version 1.0. This document defines the REQUIRED ROOT device urn:schemas-upnp-org:device:InternetGatewayDevice. The InternetGatewayDevice encapsulates all sub-devices and services for the Internet Gateway Device Control Protocol (DCP).The Internet Gateway is an "edge" interconnect device between a residential Local Area Network (LAN) and the Wide Area Network (WAN), providing connectivity to the Internet. The gateway MAY be physically implemented as a dedicated, standalone device or modeled as a set of UPnP devices and services on a PC. This version of the DCP does not cover small business networks. Discovery and access to these services from outside the home network is not recommended, unless adequate authentication, authorization and access control mechanisms are built into the device, beyond what is currently specified within the UPnP architecture framework. Figure 1 below is a conceptual illustration of a generic Internet Gateway device consisting of one or more physical WAN and LAN interfaces.
