Open ports aren't necessarily always reported

It's come to my attention that the settings for both UFW and firewalld can be overridden at a lower level by certain software packages.

If at all possible, we should have some way to check for these open ports and display them in the UI. But at a minimum, we should have some kind of warning information that this is a thing that can occur and that there might be rules somewhere else on the system that are opening other ports.
