Yes please cover NFTables if that's what you're after. Writing NFTables rules is just great. But be sure to use a very recent kernel and nft cli! With it I built my own zone based firewall. When you start to understand the use of (verdict) maps, sets and chain jumps, it is so dang powerful. Don't really wanna go back to sth like OPNSense. The man pages btw are really good and have useful examples.

I'm not sure what you mean by "from scratch" for a firewall. I'm intrerested in the software that exist and how to configure them (firewallD or else ?)

Trouble is working out how to take an arbitrary Linux distribution and figure out what 'scratch' is. Unless you just mean you're giving a tutorial on iptables?

Not for me, but these kids are desperate for "from scratch" knowledge. Please give them a pour!
