Reporting the alert behavior

In Ask mode, unanswered connections are allowed after 8 seconds for UDP or 60 seconds for TCP by default, then added to Review. You can change the wait (15–120 seconds for TCP) or have unanswered connections blocked. Strict mode blocks unmatched connections. Please include this distinction when describing alerts.
