Setting Up an OpenVPN Server

OpenVPN is a battle-tested VPN solution with broad client compatibility. The easiest way to set it up is using the angristan install script.

Step 1 — Run the Install Script

curl -O https://raw.githubusercontent.com/angristan/openvpn-install/master/openvpn-install.sh
chmod +x openvpn-install.sh
bash openvpn-install.sh

The script will ask for your server IP, port (default 1194 UDP), DNS provider, and first client name. It configures everything automatically.

Step 2 — Open Firewall Port

ufw allow 1194/udp

Step 3 — Download the Client Config

The script generates a .ovpn file (e.g., client1.ovpn) in the current directory. Transfer it to your device:

scp root@YOUR_SERVER_IP:/root/client1.ovpn ~/

Step 4 — Connect from Your Device

• Windows/macOS: Download the OpenVPN client from openvpn.net/client and import the .ovpn file
• Linux: apt install openvpn -y && openvpn --config client1.ovpn
• Android/iOS: OpenVPN Connect app — import the .ovpn file

Add Additional Clients

bash openvpn-install.sh

Run the script again and choose Add a new client.

Revoke a Client

bash openvpn-install.sh

Choose Revoke existing client.

WireGuard vs OpenVPN

• WireGuard: Faster, simpler config, modern cryptography
• OpenVPN: Wider device compatibility, better firewall traversal (TCP mode on port 443)
