Here’s a concise guide to setting up an OpenVPN server or client:

Install OpenVPN

• Linux (Debian/Ubuntu):

  sudo apt update
  sudo apt install openvpn

• Windows/macOS: Download from OpenVPN's official site.

Obtain Configuration Files

• If using a VPN provider, download their .ovpn config files.
• If running your own server, generate keys and configs (requires easy-rsa).

Run OpenVPN

• Linux/macOS (Terminal):

  sudo openvpn --config client.ovpn

• Windows: Use the GUI client and import the .ovpn file.

Basic Commands

• Start OpenVPN as a service (Linux):

  sudo systemctl start openvpn@your-config
  sudo systemctl enable openvpn@your-config

• Check status:

  sudo systemctl status openvpn

Troubleshooting

• Permissions: Ensure config files are secure:

  chmod 600 client.ovpn

• Logs: Check logs for errors:

  journalctl -u openvpn

• Firewall: Allow UDP/TCP port 1194 (default).

Self-Hosting?

For a private VPN server, follow OpenVPN’s official docs to set up a CA and issue certificates.
