Problems with restriction (csf.deny)

[JeanSantos]

Hello everyone, I hope you are well!
I've been having problems with CSF for a few months, even though it's the only firewall working on a cPanel server, when using the rules below:

tcp,udp|in,out|d=2087|d=0.0.0.0/0
tcp,udp|in,out|d=2087|d=::/0
tcp,udp|in,out|d=2086|d=0.0.0.0/0
tcp,udp|in,out|d=2086|d=::/0
tcp,udp|in,out|d=2084|d=0.0.0.0/0
tcp,udp|in,out|d=2084|d=::/0
tcp,udp|in,out|d=2083|d=0.0.0.0/0
tcp,udp|in,out|d=2083|d=::/0
tcp,udp|in,out|d=2096|d=0.0.0.0/0
tcp,udp|in,out|d=2096|d=::/0
tcp,udp|in,out|d=2095|d=0.0.0.0/0
tcp,udp|in,out|d=2095|d=::/0
tcp,udp|in,out|d=7584|d=0.0.0.0/0
tcp,udp|in,out|d=7584|d=::/0
tcp,udp|in,out|d=3306|d=0.0.0.0/0
tcp,udp|in,out|d=3306|d=::/0

I notice that there is a momentary blocking, but after a few attempts to access the blocked ports, access is allowed, which is strange, considering that the rules block completely but only for some time.

Is there any way to actually lock the doors and keep them locked?
