Internet Gateway Device
Encyclopedia
Internet Gateway Device Standardized Device Control Protocol is supported by some NAT
routers. It is a common method of automatically configuring port forwarding
, but is not an Internet Engineering Task Force
standard.
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. Universal Plug and Play
(UPnP) comes with a solution for network address translation traversal.
