Description
This article describes that with the firewall policy rule setting 'set schedule-timeout enable', a FortiGate immediately forces the session to end when the 'Stop Time' of a recurring 'schedule' object is reached.
Additional configuration steps are required to keep the session active until is finished or expired.
Scope
FortiGate.
Solution
Disabling the schedule-timeout would allow the session to remain open after the schedule has expired. The session will end by a time-out or if any FIN or RST are seen.
For example, in an office environment, YouTube use is allowed between noon and 2 PM. During that time, any YouTube traffic continues. As long as that session is open, after 2 PM end time, the existing YouTube traffic can continue, yet new sessions will be blocked. With setting 'set schedule-timeout enable',
FortiGate will terminate all the sessions when the end time of the schedule is reached.
Through the CLI, the firewall policy firewall-session-dirty option is only available after changing the system settings:
- Edit system settings:
config system settings
set firewall-session-dirty check-policy-option
end
-
Edit the firewall policy rule:
config firewall policy
edit <ID of the policy>
set schedule-timeout disable
set firewall-session-dirty check-new
end
The status of the session will change to 'persistent' once the end time of the schedule is reached and the traffic continues flowing.
