Currently, in a default deployment there was a bug where the firewall was never applied on compute nodes, and thats why we could scan port 9100, but this can be fixed (apparently it changed upstream already) at any moment and we will loose the access.

The ansible role must check if firewall is enabled and then open the 9100 port.

An example is: https://github.com/openstack-k8s-operators/edpm-ansible/blob/31a252934d2ac5d47e1b7643b56018aeca4b1fd9/roles/edpm_ovn/tasks/firewall.yml#L19
