I can prove that this is incorrect. Or are my kids mine ??

Really cool! I never touched *BSD, I have a mini PC/NAS home that ended with a minimal Arch install. This is something I can do at some point.

And what about Wireless networks?

I solved this using tailscale, no need to make your home server visible to the world, no Forwarding rules on your router. It works like a VPN on your phone/laptop and access directly your target machine in your network running taiscale. There is a completely selfhosted version called Headscale, but you’ll need an accessibile server on the internet. A cheap VPS would work for this. You can check also Zerotier, Nebula , Netmaker, pure Wireguard etc etc. Godspeed!
