Description
I have some VMs that, out of necessity, has SSHD set up to listen on a port other than 22. When installing the security package, the firewall opens 22 and blocks anything else, which breaks the Ansible playbook being used to configure the system.
As a workaround, I wrote a script that pulls the running SSHD's listening ports and opens them, which should be considered as an addition to the security package:

I may also add this as an option to the auto-installer.

Research direction
Start with the linked firewalld-open-ssh-ports script and trace how the security package configures the firewall during installation. Confirm how the running SSHD ports are discovered and where the package's firewall rules are applied. Done means non-standard SSHD ports remain reachable and the Ansible playbook can configure the system successfully.
