pfSense is a powerful open-source firewall that supports URL-based aliases for automatic blocklist updates. This guide shows you how to integrate Fraudcache threat feeds.

pfSense Overview

pfSense is a free, open-source firewall and router based on FreeBSD. It provides enterprise-grade features including URL Table aliases that can automatically download and update IP blocklists.

Integration Setup

Follow these steps to integrate Fraudcache feeds with pfSense:

1. Navigate to Aliases - Go to Firewall → Aliases → URLs in the pfSense web interface.
2. Create URL Alias - Add a new URL Table alias pointing to your Fraudcache feed URL.
3. Set Update Frequency - Configure the update interval (e.g., every 4 hours) to keep blocklists current.
4. Create Firewall Rule - Add a block rule on your WAN interface referencing the alias as the source.

Best Practices

• Use Multiple Feeds - Create separate aliases for different threat categories (spam, botnets, scanners).
• Monitor Blocked Traffic - Enable logging on block rules to identify false positives and attack patterns.
