In the case of 2.0 at least is was possible to add a dashboard widget on the server end that would display the status of a VPN connection, including letting you know if there were no users connected. That widget could provide at-a-glance confirmation of a connection at the server end.
But if the client machine is showing "VPN Interface address: Not active," I'm pretty sure that there is no connection. There should be an IP address from the VPN address space for that VPN server in that section. For example, "VPN interface address 192.168.2.2/24" at the client end, where you have "VPN interface address 192.168.2.1/24" at the server end.
Yes, this is also what I'm expecting... the client should have acquired an IP coming from the Zentyal VPN Server (by default 192.168.160.0). I'm expecting this will be displayed on the OpenVPN Daemon at the Dashboard.
In the logs I see:
