Fortinet Firewall

Firewalls monitor what is happening between your network and the rest of the world, and can monitor things such as how much data is being sent from which computer, where the data is going, and who is receiving the data.

The Fortinet Firewall event source allows InsightIDR to parse the following log types:

  • Firewall
  • VPN
  • DHCP
  • Virus
  • IDS

Before You Begin

For some FortiGate firewalls, the administration console (UI) only allows you to configure one destination for syslog forwarding. Additional destinations for syslog forwarding must be configured from the command line. Make sure that when configuring a syslog server, the admin should select the option .CSV disable. The following example shows how you can configure this setting (substitute <port_above_1024> and <collector_ip_address> with the appropriate values):

config log syslogd setting
set status enable
set format default
set facility syslog
set reliable disable
set mode udp
set port <port_above_1024>
set server <collector_ip_address>


The value for reliable determines which default protocol is used for syslog forwarding:

  • set reliable enable uses TCP by default
  • set reliable disable uses UDP by default

Instructions on how to configure additional destinations can be found here:


If your VPN is on the firewall, you do not need to configure an additional VPN syslog destination. One syslog configuration will work for both your firewall and your VPN.
