We have a vpn business running with pptp and openvpn connections. For some time we have been using both stock openvpn and some customized gui, but because of new needs we decided to get a whole new written.
We need an openvpn gui with some functionality of the [url removed, login to view] client (screenshot attached), including the integration of pptp connections and the download of configuration details before connection from a php page. Secure IP Bind and Speed guide is secondary.
Preferably to be written in C# or Java
The code should be well documented and ready for more development.
