Host side
A running LAN world or supported self-hosted server, the matching TunnelCraft integration, and a stable internet connection.
In brief: Install the compatible TunnelCraft build on the host and every player, start the world or server, then share the persistent TunnelCraft address. All TunnelCraft files are distributed through Modrinth.
Why port forwarding can fail
Traditional self-hosting requires the router to forward an incoming Minecraft port to the server. That may be unavailable behind CGNAT, managed routers, shared connections, or networks where you do not control the router settings.
Set it up in five steps
- Choose the correct build. Get the compatible TunnelCraft client, server mod, or plugin exclusively from Modrinth.
- Install the host integration. Add TunnelCraft to the LAN host or supported server platform.
- Install the client build. Every connecting player needs a compatible TunnelCraft client.
- Start the world or server. Allow TunnelCraft to establish the relay connection.
- Share the address. Send the generated persistent TunnelCraft address to your friends.

Frequently asked questions
Do I need access to my router?
No. Avoiding router port forwarding is one of TunnelCraft’s primary use cases.
Can I use TunnelCraft behind CGNAT?
TunnelCraft is intended for networks without a publicly reachable IP address or normal inbound connectivity.
Can vanilla clients connect?
No. Every connecting player needs a compatible TunnelCraft client build.
