Comment # 1 on bug 1213627 from Richard Brown

This is not a bug report· Please do not misuse our platforms to waste more of

It does not endear you to receiving the more verbose answers you clearly (and
unreasonably) demand.

Aeon exists to be a simple, user friendly desktop operating system

The presence of a firewall would lead to users workloads not working out of the
box - eg. Minecraft flatpak being unable to host games without needing to
unblock the port

There is no current userspace friendly tooling to do this automatically/easily
(eg. like Windows firewall popups)

Also, there has been many reports of firewalld conflicting with podman, where
changes to firewall rules break existing podman ports being opened and visa
versa

So, to avoid problems and keep to the original goals of the Project, there is
no firewall present

All applications should be sandboxed on Aeon, and running as the user (so not
using common ports) so the risks should be minimal.
