Technical Tip: Syslog does not receive IPS events log from Firewall

Description

This article describes an issue when the syslog server does not receive the IPS events (or other UTM events) from FortiGate Firewall.

Scope Syslog, FortiGate.
Solution

It needs to check the 'forward-traffic' option, under the 'syslogd filter' setting on Firewall:

 

config log syslogd filter
    set forward-traffic disable/enable
end

 

If the forward-traffic is enabled (by default), the IPS events (and other UTM events such as antivirus, web-filter, app-control,...) will be sent to the syslog server as expected:

If the forward-traffic is disabled, only the anomaly event (type = UTM) will be sent to the syslog server. Other UTM events will not be sent to the syslog server:
