So i have updated the NSIS script with all the components.
unrar and winscp to your server. (take a copy of your old installer folder or rename it)
Location of the installer folder is "/usr/share/untangle/openvpn/"
After a client has installed using this it will have a OpenVPN.cab file under Installation folder\WM\Installer\OpenVPN.cab (usually c:\program file\OpenVPN\WM\Installer\)
The Windows Version of OpenVPN is the Stable 2.1.1.
Note that this is just a BETA and problems may occur!
!THIS IS ALSO UNSUPPORTED BY UNTANGLE STAFF!
