Should the VPN lock icon at the top of the Configuration window be open (red) or closed (green)?
A. For OmniVPN clients, the lock icon should remain closed at all times. If you want to connect to a machine that does not have OmniVPN and is not proxied for by the local OmniVPN gateway, you will have to disconnect from the VPN by changing the lock to open. For a Katana client, the icon will usually remain open (red). Only when you wish to connect to the VPN should the icon be closed (green).
