With this script you can setup a OpenVPN server within 2 minutes. I really want to give credits to the owner of the script, but i don’t have a clue who wrote this.
wget https://git.io/vpn -O openvpn.sh
Run the installer:
sudo bash openvpn.sh
You can also do this in one command:
sudo wget https://git.io/vpn -O openvpn.sh && bash openvpn.sh
