Explicitly enable custom categories for web filter profiles, SSL/SSH inspection profiles, and proxy addresses 6.4.2

In all web filter profiles, local and remote categories must be manually enabled.

When a new threat feed connector or web rating overrides in a custom category are created, they will not impact any web filters until the category's action is changed to Monitor, Block, Warning, or Authenticate in the specific web filter's settings. If a URL is in multiple enabled categories, the order of precedence is local categories, then remote categories, and then FortiGuard categories.

In SSL/SSH inspection profiles, local and remote categories must be explicitly selected to be exempt from SSL inspection. In proxy addresses, local and remote categories must be explicitly selected as URL categories for them to apply. In both settings, if a URL is in multiple selected categories, the order of precedence is local categories, then remote categories, and then FortiGuard categories.

Web filter profiles

In this example, www.fortinet.com is added to both a custom, or local, category (Seriously) and an external threat feed, or remote, category (OnAworkComputer). The local category action is set to Monitor, while the remote category action is set to Block. When a user browses to www.fortinet.com, the local category action takes precedence over both the remote category and the FortiGuard category (Information Technology), so the Monitor action is taken.

To use local and remote categories in a web filter profile in the GUI:

1. Go to Security Profiles > Web Rating Overrides and create a custom category and add URLs to it. See Web rating override for details.

   

2. Go to Security Fabric > External Connectors and create a FortiGuard Category Threat Feed external connector to import an external blocklist.

   

3. Go to Security Profiles > Web Filter and create or edit a web filter profile.
4. Set Feature set to Proxy-based.
5. Enable FortiGuard category based filter and change the action for the Local Categories and Remote Categories entries as needed. See FortiGuard filter for details.

   When the action for a local or remote category is Allow, the category is disabled. The next category's action, in the order of preference, will be applied.

   

6. Configure the remaining settings as required.
7. Click OK.

To use local and remote categories in a web filter profile in the CLI:

1. Create a custom category and add URLs to it. See Web rating override for details.

   config vdom
       edit root
           config webfilter ftgd-local-cat
               edit "Seriously"
                   set id 140
               next
           end
           config webfilter ftgd-local-rating
               edit "www.fortinet.com"
                   set rating 140
               next
           end
       next
   end

2. Create a FortiGuard Category Threat Feed external connector to import an external blocklist:

   config global
       config system external-resource
           edit "OnAworkComputer"
               set category 192
               set resource "https://192.168.0.5/lists/blocklist.txt"
           next
       end
   end

3. Create or edit a web filter profile. See FortiGuard filter for details.

   Local categories have an ID range of 140 to 191. Remote categories have an ID range of 192 to 221.

   config vdom
       edit root
           config webfilter profile
               edit "WebFilter-1"
                   set feature-set proxy
                   config ftgd-wf
                       unset options
                       config filters
                           edit 12
                               set category 12
                               set action warning
                           next
                           ...
                           edit 23
                               set action warning
                           next
                           edit 140
                               set category 140
                           next
                           edit 192
                               set category 192
                               set action block
                           next
                       end
                   end
               next
           end
       next
   end

   When a filter is added for the local and remote categories (140 and 192 in this example), the default action is monitor.
