Setting Up a Self-Hosted VPN Server: A Beginner’s Guide for Dev

Greetings, Dev! If you’re looking for a way to secure your online privacy and bypass regional content restriction, setting up a self-hosted VPN server might be your best bet. By doing so, you can ensure that your web traffic is encrypted and routed through your own server, which gives you full control over your data and internet experience.

What is a self-hosted VPN server?

Before diving into the technicalities, it’s important to understand what a VPN is and how it works. VPN stands for Virtual Private Network, which is essentially a secure tunnel between your device and the internet. It encrypts your traffic and masks your IP address, making it difficult for third parties to intercept or track your online activities.

A self-hosted VPN server, on the other hand, is a VPN service that you host on your own server, instead of relying on third-party providers. This gives you more control over the server and the data that passes through it, which means you can maximize your privacy and security.

Why should you consider setting up a self-hosted VPN server?

There are several reasons why setting up a self-hosted VPN server can be beneficial for you:

  • Better privacy: Since you own the server, you have full control over the data that passes through it. This means that you don’t have to rely on third-party providers to safeguard your privacy.
  • Faster speeds: When you use a self-hosted VPN server, you don’t have to share server resources with other users. This can result in faster speeds and better performance.
  • Bypassing restrictions: Some countries or organizations may restrict access to certain websites or content. By using a self-hosted VPN server, you can bypass these restrictions and access the content you want.

What do you need to set up a self-hosted VPN server?

Setting up a self-hosted VPN server may seem daunting, but with the right tools and resources, it can be done easily. Here’s what you need:

  • A server: You’ll need a server that can run the VPN software. This can be a physical server or a virtual private server (VPS) that you rent from a hosting provider.
  • VPN software: There are several open-source VPN software options available, such as OpenVPN or WireGuard, that you can install on your server.
  • A domain name: You’ll need a domain name that you can use to access your self-hosted VPN server.

Step-by-step guide to setting up a self-hosted VPN server

Step 1: Choose a hosting provider

The first step is to choose a hosting provider that can provide you with a VPS or a dedicated server. Some popular providers include DigitalOcean, Linode, and Vultr.

Once you’ve chosen a provider, you’ll need to set up your server by following their instructions. This typically involves selecting an operating system, choosing server specifications, and setting up SSH access.

Step 2: Install VPN software

After setting up your server, the next step is to install the VPN software. In this guide, we’ll be using OpenVPN as it’s one of the most popular and widely supported VPN software options.

Here are the steps to install OpenVPN:

  1. Log into your server via SSH.
  2. Update your server’s package list: sudo apt-get update.
  3. Install OpenVPN: sudo apt-get install openvpn.
  4. Download the OpenVPN configuration files: git clone https://github.com/OpenVPN/easy-rsa.git.
  5. Navigate to the easy-rsa directory: cd easy-rsa/easyrsa3.
  6. Generate the server certificate and key: ./easyrsa init-pki && ./easyrsa build-ca && ./easyrsa build-server-full server nopass.
  7. Copy the configuration files to the OpenVPN directory: cp pki/ca.crt pki/issued/server.crt pki/private/server.key /etc/openvpn.
  8. Copy the example server configuration file to the configuration directory: gunzip -c /usr/share/doc/openvpn/examples/sample-config-files/server.conf.gz | sudo tee /etc/openvpn/server.conf.
  9. Edit the server configuration file: sudo nano /etc/openvpn/server.conf.
  10. Uncomment the following lines:
    tls-auth ta.key 0 # This file is secret
    key-direction 0
    .
  11. Save and exit the file: Ctrl+X, Y, Enter.
  12. Generate the ta.key file: openvpn --genkey --secret /etc/openvpn/ta.key.
  13. Start the OpenVPN service: sudo systemctl start openvpn@server.
  14. Enable the OpenVPN service: sudo systemctl enable openvpn@server.

Step 3: Configure firewall settings

Once you’ve installed OpenVPN, you need to configure your server’s firewall settings to allow VPN traffic. Here’s how:

  1. Check your firewall status: sudo ufw status.
  2. If your firewall is inactive, enable it: sudo ufw enable.
  3. Allow OpenVPN traffic: sudo ufw allow OpenSSH && sudo ufw allow 1194/udp.
  4. Reload the firewall: sudo ufw reload.
  5. Check your firewall status again: sudo ufw status.

Step 4: Configure client devices

After setting up your self-hosted VPN server, the next step is to configure your client devices to connect to it. Here’s how:

  1. Download the OpenVPN client software for your device from the official website.
  2. Copy the client configuration file to your device: scp user@server_ip:/etc/openvpn/client.ovpn ~/Downloads/.
  3. Import the client configuration file into the OpenVPN client software.
  4. Connect to your self-hosted VPN server by clicking the “Connect” button.
