Fortigate - forwrding specific type of logs

[luca1994]

Hello team,

Without FortiAnalyzer, can only specific types of logs be forwarded to a syslog server on the Fortigate firewall?

Thanks for the support

Hello @luca1994 ,

Yes, you can do this with a log filter. You can review this document about log filter.

Hi Luca

Sure you can.

config log syslogd filter
    Description: Filters for remote system server.
    set anomaly [enable|disable]
    set forward-traffic [enable|disable]
    config free-style
        Description: Free style filters.
        edit <id>
            set category [traffic|event|...]
            set filter {string}
            set filter-type [include|exclude]
        next
    end
    set gtp [enable|disable]
    set local-traffic [enable|disable]
    set multicast-traffic [enable|disable]
    set severity [emergency|alert|...]
    set sniffer-traffic [enable|disable]
    set voip [enable|disable]
    set ztna-traffic [enable|disable]
end

Yes, on Fortigate firewalls, you can configure specific types of logs to be forwarded to a syslog server. This can be achieved by setting up domain filters or log settings within the firewall's configuration. By specifying the desired log types or categories, you can ensure that only relevant logs are sent to the syslog server, helping to streamline log management and reduce unnecessary network traffic.
