Installing Tailscale on Proxmox LXC: Remote Access Made Easy

Introduction to Tailscale and Remote Access

In today's interconnected world, having secure remote access to your home lab or servers is crucial. Tailscale offers a solution that simplifies this process, making it easy to access your devices from anywhere in the world. This article will guide you through the process of installing Tailscale on a Proxmox LXC (Linux Container), enabling you to securely connect to your home lab server remotely.

What is Tailscale?

Tailscale is a VPN service that allows you to create a secure network between your devices. It uses WireGuard protocol under the hood, providing a fast and secure connection. Tailscale is available for various platforms, including:

• iOS
• Android
• macOS
• Raspberry Pi
• Linux
• Windows

One of the key advantages of Tailscale is its ease of use. It eliminates the need for complex VPN setups and makes it simple to connect your devices securely.

Tailscale Pricing

Tailscale offers a free tier that allows you to connect up to 100 devices, making it an excellent option for personal use or small teams. For larger organizations, there are paid plans available with additional features and support.

Prerequisites

Before we begin the installation process, make sure you have the following:

1. A Proxmox server set up and running
2. An LXC container created on your Proxmox server
3. Basic knowledge of Linux command line
4. A Tailscale account (you can sign up for free at tailscale.com)

Installing Tailscale on Proxmox LXC

Now, let's go through the step-by-step process of installing Tailscale on your Proxmox LXC container.

Step 1: Access Proxmox Shell

First, access the shell of your Proxmox server. You can do this through the web interface or by SSH-ing into your Proxmox host.

Step 2: Run the Installation Script

We'll be using the Proxmox VE Helper Scripts to install Tailscale. These scripts simplify the installation process. Run the following command in your Proxmox shell, replacing <CT_ID> with your LXC container ID:

bash -c "$(wget -qLO - https://github.com/tteck/Proxmox/raw/main/ct/tailscale.sh)" -s <CT_ID>

This script will:

1. Check if you've provided the correct LXC ID
2. Create the necessary configuration paths
3. Install Tailscale within the LXC container

Step 3: Reboot the LXC Container

After the installation script completes successfully, you need to reboot your LXC container. You can do this through the Proxmox web interface:

1. Navigate to your LXC container
2. Click on the "Shutdown" button
3. Select "Reboot" from the dropdown menu

Step 4: Connect Tailscale

Once your LXC container has rebooted, access its console through the Proxmox web interface. Run the following command to start Tailscale:

tailscale up

This command will generate a URL. Copy this URL and open it in your web browser.

Step 5: Authenticate Tailscale

In your web browser, you'll be prompted to log in to your Tailscale account. You can sign in using various methods:

• Email
• Google
• Microsoft
• GitHub
• Apple
• Passkey
• QR code

Choose your preferred method and complete the authentication process.

Step 6: Confirm Connection

After successful authentication, return to your LXC console. You should see a "Success" message, indicating that your LXC container is now connected to your Tailscale network.

Installing Tailscale Client on Your Computer

To access your LXC container remotely, you'll need to install the Tailscale client on your computer.

1. Visit the Tailscale website and go to the download page
2. Select your operating system (macOS, Windows, Linux, etc.)
3. Download and install the Tailscale client
4. Once installed, log in to your Tailscale account through the client

Accessing Your LXC Container Remotely

Now that you have Tailscale installed on both your LXC container and your computer, you can access your container remotely.

1. Ensure Tailscale is running on your computer
2. Open your Tailscale client and find the IP address assigned to your LXC container
3. Use this IP address to connect to your LXC container

For example, if you're running a web server on your LXC container, you can access it by entering the Tailscale IP address in your web browser.

Troubleshooting

If you're having trouble connecting to your LXC container, try the following:

1. Ensure Tailscale is running on both your LXC container and your computer
2. Check that both devices are connected to the same Tailscale network
3. Verify that you're using the correct Tailscale IP address for your LXC container
4. Check any firewall settings that might be blocking the connection

Security Considerations

While Tailscale provides a secure connection, it's important to maintain good security practices:

1. Keep your Tailscale client and LXC container updated
2. Use strong, unique passwords for your Tailscale account
3. Enable two-factor authentication for your Tailscale account
4. Regularly review the devices connected to your Tailscale network

Advanced Tailscale Features

Tailscale offers several advanced features that you might find useful:

Alternatives to Tailscale

While Tailscale is an excellent solution for remote access, there are other options you might consider:

1. OpenVPN: A more traditional VPN solution that requires more setup but offers great flexibility
2. WireGuard: The protocol that Tailscale is built on, which you can set up manually for more control
3. ZeroTier: Another mesh VPN solution similar to Tailscale
4. Nebula: A scalable overlay networking tool focusing on security and simplicity
