Hi Daniel,
Thank you for your response. I have raised a bug in github to address this.
https://github.com/containers/libpod/issues/6139
The firewall is not blocking any connections to the port and still I am facing this
issue.

Hi guys,
I am seeing a behavior:
When I run a container without root, I can reach the exposed ports from outside the host
machine. But, when I run the same container using root access, I can't reach the port
from outside.Is this an expected behavior. If yes, please help me how can I access the
ports outside host while running using root access:
I am using following command:
podman run -dit -p=8000:8000 --privileged --name coa apache:latest

Kind Regards,
Navdeep

I would expect them to behave the same, and in neither case be accessible from outside of
the machine.
We believe that modifications of the firewall rules should be done by the admin and not be
done by podman for external access to ports.
