LAN Server Properties

by rikka0w0

LAN Server Properties lets a player set the port, PvP rule and player cap when opening a singleplayer world to LAN, in the vanilla Open to LAN screen.

What it does

The mod extends the Open to LAN screen with fields for a listening port, an option to turn off online mode, a switch for PvP and a limit on the number of players. Each setting applies only to the LAN session that the player opens, so a singleplayer world keeps its own defaults afterward.

When offline mode is active, an optional setting prefers the UUID issued by Microsoft or Mojang where one is available. Players who move between online and offline mode keep their inventory contents, since the same identifier is reused. The mod is client-only, so a dedicated server has no use for it. It is published for Forge and NeoForge across six release versions, 1.20.5 – 1.21.3, under the GNU General Public License v3.0 or later, which makes it open source.

Key features

  1. Port selection for LAN

    The Open to LAN screen accepts a specific port, so the hosted world can be reached at a known address.

  2. Online mode toggle

    Online mode can be switched off in the same screen, allowing players without a Microsoft account to join.

  3. PvP and player limit

    Player-versus-player combat can be enabled or disabled, and the maximum number of players can be set before opening.

  4. Stable player identifiers

    With offline mode on, an option keeps the Microsoft or Mojang UUID so inventory survives a switch between modes.

Questions

Does LAN Server Properties need to be installed on a dedicated server?

No. Players add it to their own game, and a server needs no copy.

Which loaders does LAN Server Properties support?

Forge and NeoForge are the loaders with files. Both builds cover the 1.20.5 – 1.21.3 range.

Does the UUID option keep inventory when switching modes?

Yes, when offline mode is on and the UUID option is enabled, the Microsoft or Mojang identifier is preferred, which avoids losing inventory contents.

What the author says

This mod is client-only, installing it on a dedicated server does nothing. When this mod is installed, it will add a few new things to the "Open to LAN" Gui, which then allows the user to start the LAN game on a specific port, and also provides an option to disable the "online mode".
