Years ago, un my home, i used 2 layers of routers: 1 Linux and 1 openbsd. In front of the Linux there was a cable-modem, and behind there where a couple DMZs, with servers, and wifi, and my home LAN. I had my own DNS/DHCP servers. Almost all services were internal (files, webs, git, streaming, databases, backups, monitoring...) Nowadays, my home is rented, and i live in a nomad way were i get job. Just one laptop.
