Hi Richard, Sorry for the questions on Reddit, YouTube and the community forum. But I simply didn't get an answer on Reddit and YouTube, the question was ignored. The question was perceived as an attack on the user forum and people got defense with creative reasoning without actually being involved in the decisions or able to explain the reasoning, so people were just guessing to save face of their favorite distro. At least, that's how the thread got closed, without a definitive answer. So, I'm sorry for opening a topic here. At the time it felt like a real bug/issue and getting it here in Bugzilla before the final release of Aeon seemed like a good idea. But now I know for sure the lack of a firewall is intentional. Opening firewall ports aren't that hard in firewalld, not harder than using podman or distrobox. And I believe YaST has a GUI tool for it as well, and otherwise there is a GUI which is available in the Fedora repo named firewall-config. Sure, you need to check the logs, as you would with many more things as a dev/admin. `journalctl -fk` would be sufficient to identify firewall issues. If you really don't want to bug the users with firewall stuff, you could also protect the privileged ports by default and leave the rest open. Then at least there is something. I personally find the amount of assumptions about how users should/will use their user friendly desktop a bit concerning. Technical problems always need technical solution, depending on humans to do the right/secure thing often leads to problems. Thanks for replying. I won't bother you with this again and I hope people will find this answer through search engines as well.
