About this project
What does LobbyLink add?
LobbyLink - a lightweight utility mod that adds automated UPnP port forwarding to your Minecraft sessions using the WaifUPnP library. The mod allows you to instantly host friends in your world by automatically opening ports through your router’s firewall, eliminating the need for manual NAT configuration.
Every LAN session will become globally accessible with a single click, as the mod handles the technical networking behind the scenes to map your gateway ports. This mod will significantly simplify your multiplayer hosting and streamline connectivity without loading the game with a lot of complex mechanics.
**Usage:**First open to LAN
/ll <open/close> port - opens/closes port
/ll <o/c> port - opens/closes port
/ll list - lists all open ports
Example:
/ll open 25565
/ll close 25565
/ll o 25565
/ll c 25565
Requires UPnP support by your router
