CSF Firewall / How big deny list can be before affecting performance?
« on: December 29, 2024, 04:43:48 PM »
I understand deny list default limit is about 200 IPs. I find the need to increase more and more everyday and the list may get really large over time. I have about 400 right now. I want to know when do I have to start worrying about server performance. Most of the ip in the list are a block of many ip such as 111.222.0.0/16. So technically it is hundred or thousands of IPs every line. i assume at some point the server would crash or slow down processing large deny list correct? What is the best way to manage it?
