UPNP Devices Supported

 Universal Plug and Play (UPnP) is a network protocol that allows devices to automatically connect to each other on a local network:

    How it works
    UPnP uses standard networking protocols like TCP/IP, HTTP, and DHCP to allow devices to discover each other and connect. It can also modify router settings to open ports into a firewall.

Supported devices
UPnP is supported by many devices, including:

    Printers

Gaming consoles
WiFi devices
IP cameras
Routers
Mobile devices
Smart TVs
Torrent clients
Steam/Steam Deck
Nintendo consoles

Benefits
UPnP can make networking easier by reducing the need for manual configuration. However, it can also pose significant security risks.
Disabling UPnP
Some recommend disabling UPnP, especially on routers, to ensure that port sharing via UPnP is not possible.
