Cisco FTD and FMC

Currently Playing: Cisco FMC/FTD Prefilter Policy

🚨 Cisco FMC/FTD Prefilter Policy—Demystified in My Latest Video 🎥 Just dropped a new walkthrough where I dive into one of the most overlooked yet critical components of Cisco FTD: the Prefilter Policy. 🔍 What’s inside: - A breakdown of the default prefilter policy that ships with FMC - Step-by-step guide to creating a custom prefilter policy - Explanation of rule actions (Fastpath, Block, Analyze) and how they shape traffic handling - How and where to apply the prefilter policy within your Access Control Policy settings - A practical demo using packet tracer to catch prefilter-related issues ⚠️ Correction Alert: In the video, I mention that blocked traffic by prefilter policy doesn’t generate logs. That’s not entirely accurate. I missed enabling logging on the rule—so no logs appeared. But this “mistake” gave me the perfect opportunity to show how packet tracer can help pinpoint prefilter policy behavior when logs are missing. 📚 Whether you're tuning your FTD for performance or troubleshooting unexpected traffic drops, this video gives you the clarity and operational insight you need. Let me know what you think—and if you’ve ever been tripped up by prefilter quirks in your own deployments. #ciscoftd #fmc #networksecurity #PrefilterPolicy #Snort3 #cybersecurityeducation #packettracer #OperationalRealism #techtutorials
