Plesk Fire Wall to upload faster, and allow incremental changes
Plesk FW when having lots of rules, is SUPER SLOW, because the rules are handled by a bash script, whereas compiled executables which ia a lot faster, is not used. This is asked to be changed.
Also, please make sure the Fire Wall script does not call a DNS query for the host of each IP, as mentioned here:
https://serverfault.com/questions/85602/iptables-l-pretty-slow-is-this-normal
Also, as fail2ban may add a CIDR ip as x.x.x.x/12 within a blink of an eye, I am asking for Plesk to implement such incremental change ability on the Plesk Fire Wall As well
fail2ban-client -vvv set nginx_errors banip x.x.x.x/12
Thank you for your feedback. Unfortunately, this request contains several different suggestions, and it's not technically possible to properly handle them inside one request. Please consider creating separate feature requests for each of the items.
