Contribution How to install (D)DoS Deflate and APF (Advanced Policy Firewall) to block bad IPs

[costasias81]

I installed the (D)DoS Deflate Interface extension, but once installed, it doesn't block the IPs I ban. For example, if I block an IP, it can still access my site -_- Why does this happen? In the settings, I configured everything using Firewall: IPTABLES, but when I check with sudo iptables -L, it doesn't show the blocked IPs.
