Plugin UPnP

UPnP Minecraft Server Plugin

UPnP is a lightweight utility plugin for Minecraft: Java Edition that simplifies network access for a self hosted Minecraft server. It communicates with compatible routers through Universal Plug and Play, automatically requesting a port mapping so players outside the local network can connect without manual forwarding.

The plugin opens the server’s main port and can also manage additional ports defined in its configuration. An option allows mappings to close when the server stops, helping keep temporary access tidy. BoxToPlay presents this practical networking tool for convenient multiplayer hosting, although success depends on router support, enabled UPnP, and the network’s public connectivity.
