The window has a single numeric field with five options:

0: No change. Obey all rules as usual. Leave the field set to this unless there is an emergency.
1: Allow. Allow all activity without logging.
2: Allow+Log. Allow all activity and log it.
3: Reject. Reject all activity without logging.
4: Reject+Log. Reject all access requests and log them. Use this setting to react to and trace intrusions.
