    3. For a log entry, click the Detailed Log View icon detail_log_view_icon.png .
    4. In the Flags window, see if the Tunnel Inspected flag is checked. A Tunnel Inspected flag indicates the firewall used a Tunnel Inspection policy rule to inspect the inside content or inner tunnel. Parent Session information refers to an outer tunnel (relative to an inner tunnel) or an inner tunnel (relative to inside content).
      On the Traffic, Threat, URL Filtering, WildFire Submissions, Data Filtering logs, only direct parent information appears in the Detailed Log View of the inner session log, no tunnel log information. If you configured two levels of tunnel inspection, you can select the parent session of this direct parent to view the second parent log. (You must monitor the Tunnel Inspection log as shown in the prior step to view tunnel log information.)
    5. If you are viewing the log for an inside session that is tunnel inspected, click the View Parent Session link in the General section to see the outside session information.
