DescriptionWith the firewall policy rule setting 'set schedule-timeout disabled', a FortiGate immediately forces the session to end when the 'Stop Time' of a recurring 'schedule' object is reached.
Additional configuration steps are required in order to keep the session active until is finished or expired.
SolutionThrough the CLI, follow the steps given below:
1) Edit the firewall policy rule
# config firewall policy
# edit <ID of the policy>
# set schedule-timeout disabled
# set firewall-session-dirty check-new
# end
2) Edit system settings
# config system settings
# set firewall-session-dirty check-policy-option
# end
The status of the session will change to 'persistent' once the end time of the schedule is reached and the traffic continues flowing.
