Set timeout on idle for VPN (Cisco IPsec)? Anyway to set a idle timeout on VPN? I want my VPN connection to drop automatically after idling for 5 minutes.

Using Lion 10.7.3 and built-in VPN Client (Cisco IPsec).
Go to System Preferences > Network. Select your VPN connection from the sidebar. Click on Advanced. In the first tab ("Options"), there should be the option "Disconnect if idle for X minutes".
