Edit: This issue is possibly a known one: see "Podman can not create containers that bind to ports < 1024"

It's impossible to reach any exposed privileged port from external net when running podman

sudo podman run -p 80:80 -it nginx

Setup: dedicated Centos 8, clean install + docker, no firewalld, iptables at "allow-all" default ruleset. With docker however it works without problem.

What I was trying to run which needed to listen to privileged ports is a certbot inside docker. Motivation is to avoid installing python dependencies or else downloading and running unknown binary.
