- yeah webserver return 403 but i want to execute blok rule before it even hit nginx proxy or apache

i did  itables -A INPUT -s 119.29.93.25 -j DROP which added IP to drop chain and stopped the flood ( got 3 MB / munute log size )  - is there a rule / way to make it auto seems that CSF drop rule make server to respond with 403 but traffic still hit it and make log spam
