Eliminate Reverse DNS lookups when Plesk Firewall rules are applied or activated
Plesk firewall does a reverse DNS lookup when applying rules (it used to do the same again on activation but I am not sure but the cache helps there) - no reason to do a reverse look as it takes long 4-5 minutes for each step for long list of IPs; malformed IPs are trapped when adding the IP so that should not matter

Unfortunately, we have to close your request, because over the years it has not become quite popular for further implementation.

Please firewall needs a thorough dressing up. It has been pretty much useless since 9.x. Probelms:
1. Both "Apply" & "Activate" take a very long time with just CIDR blocks added.
a. The reason is that for both Apply and Activate, plesk does a reverse DNS lookup for each and every IP or Net in the table
b. Very simple solution - for Apply no need for DNS lookups it is useless
c. For Activate use iptables -n ....
This is such an easy fix and has not been taken care of for years; I have made this comment way back.
There are numerous other problems not just with the F/W but other areas as well.
Thinking of moving to CPANEL for Linux.
