Automatically updated CloudFlare DNS Gateway Ad Blocker

Cloudflare Gateway Ad Blocker (CGAB)

Cloudflare Gateway allows you to create custom rules to filter HTTP, DNS, and network traffic based on your firewall policies. This is a collection of scripts that can be used to get a similar experience as if you were using Pi-hole, but with Cloudflare Gateway - so no servers to maintain or need to buy a Raspberry Pi!

About the individual scripts

• cf_list_delete.js - Deletes all lists created by CGAB from Cloudflare Gateway. This is useful for subsequent runs.
• cf_list_create.js - Takes a blocklist.txt file containing domains and creates lists in Cloudflare Gateway
• cf_gateway_rule_create.js - Creates a Cloudflare Gateway rule to block all traffic if it matches the lists created by CGAB.
• cf_gateway_rule_delete.js - Deletes the Cloudflare Gateway rule created by CGAB. Useful for subsequent runs.
• download_lists.js - Initiates blocklist and whitelist download.

Features

• Support for basic hosts files
• Full support for domain lists
• Automatically cleans up filter lists: removes duplicates, invalid domains, comments and more
• Works fully unattended
• Whitelist support, allowing you to prevent false positives and breakage by forcing trusted domains to always be unblocked.
• Optional health check: Sends a ping request ensuring continuous monitoring and alerting for the workflow execution.
