Install Gentoo on a Mac Mini (G4 PowerPC)

Note: This article is primarily translated by DeepL and I did not really check everything due to a lack of time. I guess you will get my point - I guess. Why a computer from 2005? Older computers always fascinated me. But I do not limit myself to a certain era, like the 80s or 90s. That’s why I still own a Commodore 64 with datasettes, but also my first laptop (IBM ThinkPad T23) from 2003.

Bug in Firewalld

My personal experience level I am administrating many servers for our university since 2016. Of course we try to keep them as safe as possible by using firewalls. They are used to protect our network from unwanted visitors and to protect every single node from each other. Only administrative and known service ports are open for specific IPs. Additionally we are NATting a lot of traffic. So you could say I am firm with the usage of firewalls.
