I’ve been watching some One Marc Fifty stuff on YouTube. I can follow him well, and I’m decent at much of the hardware stuff. At least I can compile OpenWRT or do a basic Gentoo install with a custom kernel. I dread staring at NFTables, but can hack around some. I don’t fully understand networking from the abstract fundamentals. Are there any good sources that break down the subject like Ben Eater did with the 8 bit bread board computer, showing all the basic logic, buses, and registers surrounding the Arithmetic Logic Unit? I’m largely looking for a more fundamental perspective on what are the core components of the stack and what elements are limited to niche applications.
I just realized I want to use self signed client certificates between devices. It was one of those moments where I feel dumb for the limited scope of my knowledge about the scale of various problems and solutions.

I’m not familiar with the Ben Eater series, but there are certainly a couple options to check out.
Mark Ferneaux did a fantastic series on the workings of pfSense. It’s a little dated, but the core concepts are still sound and apply to networking generally.
There are also several sites that do in-depth networking topics with a focus on certifications. My favorite of the bunch is Viatto.
I also quite like The Network Berg, though his videos are specifically focused on Mikrotik.
