You should not host anything that’s going to be public facing on your home network in 2026, period. Get a cheap German VPS and go nuts with it. There’s simply too much at stake opening up your home router/firewall for such little gain. Plus, being a residential IP behind NAT might just make it straight up impossible.
I host my own email and a matrix server. I would never think of exposing my home network to the internet. I use tailscale to get into the homelab, anything exposed to the net lives somewhere far, far away.
