VPN on Web Hosting: Can You?

G5 Cyber Security

TL;DR

Generally, no. Most web hosting providers don’t let you directly install and run a VPN server on their shared or even VPS hosting plans. It breaks their terms of service, impacts server performance for everyone, and poses security risks. You can usually connect *to* a VPN from your website server, but not host one yourself.

Why You Can’t Usually Host a VPN

  1. Terms of Service: Web hosts typically prohibit running VPNs or proxy servers on their infrastructure. They want to control the network environment and prevent abuse.
  2. Resource Intensive: VPN software needs significant CPU, memory, and bandwidth. This can slow down other websites sharing the same server.
  3. Security Concerns: A poorly configured VPN could create security vulnerabilities for the entire hosting provider’s network.
  4. IP Address Issues: Hosting a VPN often involves using dedicated IP addresses, which most shared hosting plans don’t provide.

What You *Can* Do

Here are your options if you need a VPN connection related to your website:

1. Connect Your Server *to* a VPN

This is the most common and acceptable approach.

  1. Choose a VPN Provider: Select a reputable commercial VPN service (e.g., NordVPN, ExpressVPN, Surfshark).
  2. Install VPN Client Software: Install the provider’s client software on your web server. This is usually done via SSH. 
    sudo apt update
    sudo apt install openvpn

    (Example for Debian/Ubuntu – instructions vary by OS and VPN provider)

  3. Configure the Connection: Follow your VPN provider’s instructions to configure a connection profile. This involves downloading configuration files (.ovpn) and entering your credentials. 
    openvpn --config /path/to/your/config.ovpn
  4. Route Traffic (Optional): If you only want specific traffic to go through the VPN, configure routing rules using iptables or similar tools. This is an advanced step. 
    sudo iptables -t nat -A OUTPUT -p tcp --dport 80 -j REDIRECT --to-ports 12345 # Redirect HTTP traffic to a local VPN port

2. Use a Dedicated Server or VPS

If you absolutely need to host your own VPN, rent a dedicated server or Virtual Private Server (VPS) from a provider that allows it.

  1. Choose a Provider: Select a VPS provider with clear policies on running VPNs.
  2. Install VPN Software: Install and configure VPN software like OpenVPN, WireGuard, or SoftEther VPN. 
    sudo apt install openvpn easy-rsa

    (Example for Debian/Ubuntu)

  3. Configure Firewall: Set up a firewall (e.g., ufw) to protect your VPN server. 
    sudo ufw allow 1194/udp # Allow OpenVPN traffic on UDP port 1194
  4. Manage Security: Keep the VPN software updated and follow security best practices.

3. Consider a Reverse Proxy with SSL

This doesn’t create a traditional VPN, but it can add a layer of encryption.

  1. Install a Reverse Proxy: Use software like Nginx or Apache as a reverse proxy. 
    sudo apt install nginx
  2. Configure SSL/TLS: Enable SSL/TLS to encrypt traffic between your users and the reverse proxy. Let’s Encrypt provides free certificates. 
    certbot --nginx -d yourdomain.com
