What You Will Learn

• How cloud VPN systems work in real-world infrastructure
• How to deploy projects using Railway
• How Tailscale creates secure private networks
• How exit nodes work in VPN routing
• Basic cloud networking concepts for beginners

Tools Used

• Railway – Cloud platform for hosting applications
• Tailscale – Secure mesh VPN networking tool
• GitHub – Source code repository for deployment

Important Concept

Railway is not a traditional VPS. It is a Platform-as-a-Service (PaaS), which means you cannot install VPN software manually like on a server. Instead, we use Tailscale to create a secure network layer between devices.

Step 1: Create Tailscale Auth Key

• Login to Tailscale account
• Go to Admin Console → Settings → Keys
• Click “Generate Auth Key”

Enable Reusable and Ephemeral, then copy the key.

Step 2: Deploy on Railway Using GitHub Repository

We will now deploy using a ready-made GitHub project for easier setup.

• Open Railway dashboard
• Click New Project
• Select Deploy from GitHub Repo
• Connect your GitHub account

Use this repository:

railway_tailscale_vpn GitHub Repository

Set Environment Variable

• Open Railway project settings
• Go to Variables section
• Add:

TAILSCALE_AUTHKEY = your auth key

Click Deploy and wait for build completion.

Step 3: Enable Exit Node

• Go to Tailscale Admin Console
• Open Machines section
• Select Railway instance
• Enable “Use as Exit Node”

This allows your cloud server to route internet traffic securely.

Step 4: Connect Your Device

• Install Tailscale on PC or mobile
• Login with same account
• Go to settings
• Enable “Use Exit Node”
• Select Railway machine

Now your internet traffic will route through your cloud setup for learning purposes.
