When monitoring the traffic logs using Monitor > logs > Traffic, some traffic is seen with the Session End Reason as aged-out. For instance, if you allow HTTPS to the internet and the traffic was blocked as a threat, in the log details you may see: This traffic was identified as a web ad and blocked per your URL filtering policy, Objects->Security Profiles->URL Filtering->[profile name] is set to "block". That depends on why the traffic was classified as a threat. The following pricing is based on the VM-300 series firewall. VM-Series Models on AWS EC2 Instances. Review the correlated log entries in the lower panel to identify which threat prevention feature enacted a block. for configuring the firewalls to communicate with it. You can change the entire category from "block" to "allow" (not ideal) or create a custom URL filter (Objects->Custom Objects->URL Category->[category name]) and allow just that category in your URL filter. - edited A 64bit log entry identifier incremented sequentially; each log type has a unique number space.
