I was lazy in my langauge. I meant DOCSIS modem -> router/firewall with everything -> access points or hardlined ethernet recipients. Current setup is Arris dedicated (non-wifi) 3.1 to Linksys mesh.
99% of demands are local network performance. No mega streaming needs or huge external traffic. Upload on wireguard (Jellyfin or otherwise) will be pretty limited to a single user at once. But this is not critical. Local network is my usecase.
I am 500/50, will probably up to fiber as soon as it’s available. But again not a lot of external traffic, hyper limited.
So get a switch between the router/minipc/whatever and the rest of the local network instead of many on-board ethernet?
What is the software setup when you’re actually configuring the minipc/box? Beyond the hardware architecture of the local network, what is the actual stack I should be pursuing and how is it implemented?
For example: I read lots of great things about OPNsense, Wireguard, DietPi… but I don’t know what the exact stew should be and how to set it up ELI5 style.
