If you recently have upgraded your Fortigate Firewall to FortiOS 4.0 MR3 perhaps you have noticed an increase in the traffic log.

FortiOS 4.0 MR3 has the value of extended-traffic-log enabled by default instead of previous versions where this value was disabled by default.

If you want to disabled this new default option, here you have the commands:

  • config log [memory|disk|fortianalyzer|...] 
  • filter set extended-traffic-log [enable|disable]

What does the log filter setting "other-traffic" display?
