podman container doesn't allow external connections

[slonvpalto]

Tried using the tutorial https://github.com/containers/podman/blob/main/docs/tutorials/basic_networking.md

Issue: followed the tutorial above and ran under root user:
podman run -dt --name webserver -p 8080:80 quay.io/libpod/banner

• when initiated connection from local machine: curl :8080 - works fine, got the banner
• when initiated connection from external machine: curl :8080 - connection stuck
• when adding "--network host" to "podman run" command - connection from external machine works fine

The tutorial above doesn't contain any additional requirements or tricks to allow connections from external machine to rootful container. We have a bug either in podman or in tutorial.

If you have an issue in RHEL I suggest you contact the Red Hat support.
Upstream only supports the latest version so my first question is to try this with the latest versions.

As far as your command goes yes this should work without extra configuration normally. Do you have any firewall settings configured on your own? Any specific sysctl that block external routing? How do you connect from another machine ipv4 or ipv6? Have you checked the firewall rules the were created by podman to configure the port forward?

Without any specific details on your environment it is impossible to know what is going on.
