Settings for this are available via CLI (disabled by default): Enable implicit firewall policy logging. Go to System Settings > Log Forwarding. Export a small group of such logs from the logging unit (FortiGate GUI, FortiAnalyzer, FortiCloud, Syslog, etc).Packet capture (sniffer): On models with hardware acceleration, this has to be disabled temporarily in order to capture the traffic.It is better captured from command line and log the SSH output.Debug flow (firewall logic): Common cases where traffic is not passing, and shown in debug flow for new sessions:'Denied by forward policy check'. Check the ID number of this policy.- Make sure that the session from source to destination is matching this policy:(check 'policy_id=' in the output). 04-07-2021 option-resolve-port: Enable/disable adding resolved service names to traffic logs.
