When the connection is established, the VPN Client window stays in the foreground to allow the VPN client to be reauthenticated during a rekey by the VPN device. To send the VPN client window to the background, press Ctrl-Z and enter the bg command at the command line prompt. If the VPN device you are connecting to is configured to support rekeying and you send the VPN client window to the background, the tunnel disconnects when the first rekey occurs. The VPN client responds to rekey triggers based on time, not data. If you want VPN client connections rekeyed, you must configure the concentrator so that the IKE proposal is set to rekey every 1800 seconds and IPSec parameters are set to rekey every 600 seconds
