Comprehensive Guide: Setting up Tailscale for Self-Hosting

Step 1: Install Tailscale Server

Download the Tailscale server binary for your platform: https://tailscale.com/downloads

Run the server with the following command: ./tailscaled --server-addr 0.0.0.0:8345

This starts the Tailscale server on port 8345 and listens on all interfaces.

Step 2: Obtain Public and Private Keys

Generate a Tailscale network key pair: ./tailscaled --network-key-gen

Store the public key in a secure location for clients to connect.

Keep the private key confidential.

Step 3: Configure Clients

Download the Tailscale client binary for each device: https://tailscale.com/downloads

Run the client with the following command: ./tailscaled --node-addr <public_ip>:8345 --network-key <network_key_public>

Replace <public_ip> with your Tailscale server's IP address and <network_key_public> with the public key obtained in Step 2.

Step 4: Join the Network

Once clients are configured, they will join the Tailscale network and be able to communicate with each other over any network.

Step 5: Advanced Configuration (Optional)

Custom Network Name: Use --network-name <network_name> to assign a specific name to your Tailscale network.

Remote Access: Enable remote access by running ./tailscaled --remote-access on the server. This allows non-Tailscale devices to connect to the network using a VPN.

Authentication: Implement authentication using ./tailscaled --auth-file <path/to/auth_file> on the server. This requires creating an authentication file containing user credentials.

Tips:

Use a static IP address for your Tailscale server to avoid connectivity issues.

Configure firewall rules to allow traffic on port 8345 for Tailscale communication.

Consider using a dedicated machine or container for the Tailscale server for better performance and security.
