Improved Lan System - Enhanced Local Network System
The Improved Lan System mod provides two useful commands for managing local gameplay. Using the /closelan command, you can instantly close the LAN server without reloading the world. The second command /lan allows you to start local network mode with parameter configuration.
To launch LAN mode, you need to specify three mandatory parameters: the game mode type (true or false to enable/disable cheats) and the port number (any number from 0 to 65536, it's recommended to use non-rounded values like 20000 or 20010).
Important advantage: the mod only needs to be installed on the server side. This means it's sufficient to install it in the world that other players connect to, and clients no longer need to install the mod.
