Ubuntu server and client configuration 20.04-22.04

wget https://git.io/vpn -O openvpn-install.sh

chmod +x openvpn-install.sh

sudo ./openvpn-install.sh

$ sudo systemctl stop openvpn-server@server.service # <--- stop server

$ sudo systemctl restart openvpn-server@server.service # <--- restart server
$ sudo systemctl status openvpn-server@server.service # <--- get server status
