 ### 2.) Web Filter Blocks
 While the fortigate firewalls do have built in web-filters for advertisements and known malicious actors, it is not blocking everything I would like it to. As such I wanted to use the plethora of Pie-Hole block lists, especially the lists at this amazing site https://firebog.net/. The issue is that these lists are not formatted in the way the Fortigate external threat feeds will accept. As a result I made a script that will download all of the separate lists, format the entries to be compatible with the external threat feeds, and save the entries into separate files with 131,000 entries per file since that is the limit of the threat feeds.

The script formats the data in a way compatible with the fortigate since pie hole lists are formatted as HOST files. The script also performs a little more filtering, but most importantly to removes duplicate entries. For example, currently the PHP script downloads (as of 12/22/2025) 2,705,927 entries and after removing duplicates, has 1,894,589 unique entries being blocked.

 I then use the WEB filter profile within my Fortigate firewall with the resulting ```web_blockX.txt``` files as external threat feed to block significant amounts of ads, tracking, and malicious sites on top of what fortinet already blocks.
