Description

This article explains how to create local custom override categories in FortiOS.

Solution

In FortiOS a URL or a list of URLs can be added to a custom override category in order to have a block action applied when the default category to which the URL has its action set to allow, monitor, warning or authenticate. This is also useful for when a URL has not yet been rated and the unrated web filter category has been blocked.

For example: In order to block www.cnn.com whilst allowing, monitoring, warning or authenticating the default web filter category News and Media, one method is to add www.cnn.com to a custom category and setting the action of block to that local custom category.

These categories exist in the default base config of FortiOS, they are titled custom1 and custom2.

Run the following commands in the CLI to create a local custom category:

config webfilter ftgd-local-cat
edit "name_of_custom_filter"
end
