Issue Plesk Firewall does not add changes to zone (CloudLinux)

[DavidDV]

Server operating system version

CloudLinux 8.9

Plesk version and microupdate number

Versión 18.0.61 #5

I am using Plesk firewall extension to open some ports on my CloudLinux 8 server but I am unable to open certain ports because the Plesk firewall interface does not add the rule to firewalld:



The operating system has no modifications and I am not using security extensions like Imunify360. I have tried reinstalling plesk firewall, rebooting, etc.

Any ideas?

Firewalld is only supported by Plesk for RHEL 7 based systems. On all other OSes (including Cloudlinux 8) the Plesk firewall uses iptables.

Do I have to change anything in the operating system to stop using firewalld? I haven't touched anything, the system came like that, shouldn't Plesk use iptables and open the port? Although in the Plesk interface it says it is open, it really isn't.

# systemctl stop firewalld.service
# systemctl disable firewalld

Yes, you can use the commands posted by @Bitpalast to stop and disable firewalld.

It does. But firewalld is (as far as I can tell) blocking the port, which is why it is better to get rid of firewalld.
