红石联机
by 3629236855
红石联机 lets players host a Minecraft LAN world for friends outside the local network, opening it through a tunnel without router configuration.
What it does
The mod is an intranet penetration tool for Minecraft LAN worlds. A player who opens a world to LAN normally has to forward a port on the router before remote players can join. Here a tunnel is created with one click, and the connection address is copied to the clipboard so it can be sent to friends.
The tunnel connects through several relay servers, and the mod selects the one with the lowest latency automatically. It also generates a cache API key on first use. Players who connect through it can be allowed to join without an authenticated account, which is the cracked-player support, while online mode can be disabled in the settings.
The mod is built for Fabric and targets 1.20.1 only. Only the server needs it, and players join without installing anything. The code is open source under the GNU General Public License v3.0 or later, and the source is published as a public link. The latest file, 1.0.0, is on the beta channel and was published on 2026-07-09.
Key features
One-click LAN tunnel
A tunnel to a LAN world is opened with a single action, without editing the router or forwarding a port.
Connection address copied
The address for remote players is copied to the clipboard as soon as the tunnel is ready.
Relay selection by latency
Several relay servers are available, and the one with the lowest latency is chosen automatically.
Cache API key generation
The mod generates the cache API key itself, so no manual key entry is needed to start a tunnel.
