OpenToPublic
by BoBkiNN
With OpenToPublic, a host can open a single-player or LAN world to players outside the local network and set its server options from one place.
What it does
The mod lets a host open a world to the wider internet from inside the game, through an Open WAN button that works alongside the existing Open to LAN flow. Server settings such as online mode, PVP, the port, the MOTD with color support and the maximum player count can be changed before the world is opened. Additional ports can be added, and UPnP can be enabled from the config file. The router still has to forward the chosen port for outside players to connect.
Only the host needs the mod for the open world to work, while players joining from outside can connect without installing it. The mod is published for Fabric, Forge, NeoForge and Quilt, with the latest files built for 1.21.8. Cloth Config API is an optional dependency that adds a settings screen. The project is open source under the MIT License, and its source code and issue tracker are public.
Key features
Open WAN button
A button on the pause screen opens the current world to outside players, instead of only the local network.
Server settings in-game
Online mode, PVP, the port, the MOTD with colors and the maximum player count are set before the world is opened.
Extra ports and UPnP
Additional ports can be listed in the config file, and UPnP can be turned on for automatic port forwarding.
Streamer mode
An option hides IP addresses while the world is open to the internet, which suits streaming.
