UPnP Internet Gateway Device (IGD) Standardized Device Control Protocol is a NAT
port mapping protocol and is supported by some NAT routers. It is a common
communication protocol of automatically configuring port forwarding. Applications
using peer-to-peer networks, multiplayer gaming, and remote assistance programs
need a way to communicate through home and business gateways. Without IGD one
has to manually configure the gateway to allow traffic through, a process which is
error prone and time consuming.
This device supports the UPnP Internet Gateway Device (IGD) feature.
