Tunnel Craft Plugin (26.3, 1.21.1) – Host Multiplayer Worlds Without Port

Tunnel Craft Plugin lets you host a Minecraft server or share a LAN world without opening router ports or needing a public IP address. This plugin routes network traffic through a WebSocket relay network so friends can join from anywhere. Each server gets its own permanent address to share with other players. All joining players must also install a matching Fabric or NeoForge client version to connect, because vanilla clients cannot use this custom tunneling protocol.

Features:

• No Port Forwarding: Lets you host servers and LAN worlds without changing router settings or exposing a public IP address.
• Permanent Server Address: Gives your server a fixed, easy-to-share address like plpx-abc123 that players enter in their server list.
• Extra Port Forwarding: Allows Premium users to forward extra TCP and UDP ports for tools that need separate connections, such as Simple Voice Chat.
• Works across Bukkit, Paper, Purpur, and Spigot servers, as well as Fabric and NeoForge platforms.
• Routes traffic through a dedicated relay network so your home network stays private.
• Requires all joining players to run the matching client version on Fabric or NeoForge.

Comparison with e4mc:

Commands:

• /tunnelcraft show: displays the connection address when sharing a singleplayer world to LAN.

How to Use:

1. Start your dedicated server and copy the connection address shown in the server console.
2. For singleplayer worlds, open the world to LAN and type /tunnelcraft show to get your address.
3. Make sure every friend who wants to join has the matching Fabric or NeoForge client version installed.
4. Share the address with your friends so they can add it to their multiplayer server list and join.
