How do I keep my VPN turned ON?

If I leave my computer on overnight and Norton VPN is "ON" when I leave or Log Off..When I return the Norton Icon is checked yet VPN has turned off. Scan and LiveUpdate were done fine in that time period.

[Edit: Calrified the subject]

Still VPN Turns Off on Log Off Windows..not shut down. Updates work fine but VPN disconnects..

Can I prevent this?
