This script accepts an openvpn file as an input parameter and will inject you're username and password into the ovpn file to allow login without having to type a password. Additionally you can configure a default ovpn file by naming the file default.ovpn.
It will also use iptables to ONLY allow connections to the IP in the .ovpn file. This prevents any leaks from a VPN drop as all other connections will not be allowed.
