Run a private Minecraft server with Tailscale
Minecraft is a popular multiplayer game, in which players can connect to a Minecraft world hosted within one of the player’s running game or can connect to a standalone server hosting a world.
Without Tailscale, setting up a Minecraft server to be reachable from outside the home means either:
- paying for third party hosting, or
- opening ports in the firewall, potentially allowing access to any rando on the Internet
With Tailscale, you can share it from anywhere with just the people you want.
In this guide, we’ll show how to set up a Minecraft
bedrock_server and connect
to the server from anywhere using Tailscale.
You will need a Linux server. These instructions assume a Linux server or VM running within the home, behind a firewall. Tailscale lets clients connect to computers wherever they are, so you do not need to worry about the accessibility of the machine. It just needs to be on the internet. If you sign up for a VM hosted by a cloud provider, make sure to block almost all access in the firewall.
The instructions in this guide assume you are using Ubuntu or Debian, though the changes for other Linux distributions are small.
bedrock_server supports both Windows and Linux. We’ll cover Linux in
We recommend creating a user to run the Minecraft server, and installing some packages we’ll need later:
adduser --system --home /opt/minecraft minecraft addgroup --system minecraft adduser minecraft minecraft chsh --shell /bin/bash minecraft apt install unzip curl tmux git wget
Download the current version of the Linux
bedrock_server binary from
https://www.minecraft.net/en-us/download/server/bedrock. It is best to
do this as the minecraft user just created:
su -s -u minecraft cd ~ wget "download path copied from https://www.minecraft.net/en-us/download/server/bedrock"
bedrock_server is updated relatively frequently, and when the
Minecraft game app is updated it requires the new version of the server.
So we’ll prepare for future updates by storing the server files in git:
git init . unzip bedrock_server*.zip rm bedrock_server*.zip git add -A git commit -m "Initial bedrock_server"
bedrock_server update can be stored in git. Pay special attention
server.properties, where any future
will overwrite any customizations you may have made.
systemd is a way to automatically start services when the system boots. We’ll
create a few files to have
bedrock_server start automatically.

Also make the shell scripts executable:
chmod +x /opt/minecraft/start.sh /opt/minecraft/stop.sh
As root you should now
systemctl start minecraft and voilà, you are running
a Minecraft bedrock edition server.
As the minecraft user, you can connect to tmux to see the server console:
sudo -s -u minecraft tmux attach
To detach from tmux and leave
bedrock_server running, press Ctrl-B
then “d” for detach.
Tailscale is available for essentially any modern Linux distribution, though the installation instructions may vary slightly.
Once installed and active on the tailnet, the Minecraft
bedrock_server can be
reached from any of your other Tailscale clients.
You’ll need the Tailscale client installed, from the App Store for iOS devices and the Play Store for Android. You’ll also need the Minecraft app.
In the Minecraft app, select Play, and then select the Servers tab. There will be a number of promoted third-party servers in the list, but scrolling to the bottom there will be a button to Add Server.
Add the details of the server just created, including the Tailscale IP address (the 100.x.y.z IP address, which can be looked up in the Tailscale app or in the admin console for your network)
You’ll be asked to login to XBox Live before being allowed to connect to the server. live.com accounts are free, and you don’t have to have an XBox to create one. Tailscale never receives the live.com account, Minecraft simply requires it before connecting.
