Firewalld

You should disable the system firewall, as it is not required:

[root@rhel-tiger-14-6 ~]# systemctl is-enabled firewalld
enabled

[root@rhel-tiger-14-6 ~]# systemctl is-active firewalld
active

[root@rhel-tiger-14-6 ~]# systemctl disable --now firewalld
Removed /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

[root@rhel-tiger-14-6 ~]# systemctl is-enabled firewalld
disabled

[root@rhel-tiger-14-6 ~]# systemctl is-active firewalld
inactive
