network: contains configuration to add a virtual network device (i.e.
tun1366) and custom DNS servers
openvpn: OpenVPN configuration file to connect to PIA VPN servers
firewall: firewall configuration which passes all traffic through VPN and rejects any request when OpenVPN is down
NOTE: there are a number of other files required to be available under
/etc/openvpn for this approach to work:
pia.auth: VPN credentials in two lines, first the username and the second the password
