Does Podman actually open the ports like Docker do? I was of the impression it did not. But it’s entirely possible that I might be wrong.
I would be disappointed if it did. I’m moving to Podman as well just because of the firewall issue in Docker.
Edit: After some searching I’m convinced Podman does not mess with the firewall unless instructed to do so. Have you tested that the ports are actually opened up?
That does sound like it’s something else.
