UPnP IGD Specification

The UPnP IGD (Universal Plug and Play Internet Gateway Device) specification defines how routers automatically manage network traffic between your local devices and the internet. It allows devices like computers, gaming consoles, or printers to request the router to open or close specific communication channels (ports) without manual configuration. This helps applications such as gaming, video streaming, or VoIP work smoothly by ensuring data flows correctly. Essentially, UPnP IGD simplifies network setup, enabling devices to communicate efficiently with the internet while the router dynamically manages the necessary connections.
