openvpn_inc
Hi zk,
If you are talking about OpenVPN Connect, it is not designed to work that way; it is designed to try to always remain connected. Perhaps you'd have better luck trying with the community (open source) client? I think you should be able to script something in PowerShell to check the connection and start or stop it as appropriate, when the home network is detected?
I'm not a Windows user, so I don't know details, but I do know that PowerShell has lots of cmdlets and extensive documentation.
