Firewall Cleanup - Unused Policies

Here is a neat little trick that comes in handy in a number of situations. Let's assume that you inherit a Fortigate firewall with hundreds of policies defined. The previous administrator did not provide you with any information on what the rules do. You are left to figure out if all the rules are still required.
If you are running FortiOS 3.0 MR5 Patch 3 and later an easy way to see if your firewall policies are still being used is to modify the "Column Settings" under Firewall -> Policy. Select "Count" and click the right arrow to move it from "Available fields" to "Show these fields in this order".

Now your policies will show the "Count" column with indicates the number of times the policy has been invoked and the number of bytes transferred. Start your investigation with any rules that are "0/0" (i.e. not in active use) and continue by working on rules that have a low hit/byte count.

Bulk Command Import

Ever had to move a firewall configuration to a different hardware platform with different interface names? Ever had to create a gazillion new objects and paled at the prospect of spending hours in front of the web GUI?

A very handy but somewhat hidden feature to relieve you from your nightmares is the bulk import of CLI commands. Sure, you can copy a text document and paste it into an SSH CLI session. However I have noticed in the past that this does not always work terribly well. A good way to make sure all commands are successfully transferred is the "Import Bulk CLI Commands" menu. You can find it under System -> Maintenance -> Backup & Restore Tab: Advanced. Click on the blue triangle next to "Advanced" to expand the section and make it visible.

  • Prepare a plain text file with all the commands you want to import
  • Below "Import Bulk CLI Commands" click "Browse"
  • Select the text file which contains your firewall commands
  • Click "Import Now"
Et voila, all your commands have been imported assuming of course a properly formatted text file.

Monitoring Fortinet Firewalls with Cacti

Cacti ( is a popular SNMP graphing tool that can monitor pretty much any device which supports SNMP. Here is a quick guide on how to configure Cacti to monitor Fortigate interfaces, total active sessions, and system resource utilization. I will leave installing Cacti up to you :)

Start in the Console by clicking Data Templates in the Templates section. Click Add in the top right corner and enter the values from the following screenshot. Then click Save.

Afterwards create two more Data Templates based on the next two screenshots.

The Data Templates tell Cacti which values (OIDs) to monitor.

Next, go to Graph Templates in the Templates section. As before click Add in the top right corner and define the following two Graph Templates: Fortigate – System Resources and Fortigate – Total Sessions. The System Resources graph will monitor CPU and memory utilization in one combined graph.

Next create a Host Template as per the screenshot below.

Now you are ready to start monitoring firewalls. Under Management go to Devices and click Add. Define a new device. Sample values are in the screenshot.

That’s it. Graphs will start to update after Cacti’s next polling cycle.
