Yeah what you’re talking about is a DMZ, it still won’t help a ton if you don’t have strict firewall controls inside your network too.

I just use wireguard with firewall rules to restrict to just my server with my docker containers on it and my DNS

I still use a reverse proxy, but to get into my network you need to be on VPN. It’s more secure for me I guess.

I use traefik forward auth, even inside my network on VPN, for an extra layer of security for some apps.

My opinion is that port 443 getting accidentally misconfigured by me is just too likely a scenario. With wireguard on my router I also am able to restrict traffic to ONLY my webserver and DNS servers for my devices.

So I guess that’s another positive of wireguard, you can use your own DNS servers for all your phones all the time and always have ad blocking with pihole or something similar, even on mobile.

By using VPN I don’t have to worry about accidentally exposing a website with a copy paste error or something over my reverse proxy. I can also easily restrict who has access to my VPN and do routing rules from my router per device or subnet (for people who aren’t in my family I have a separate subnet I assign with more strict firewall rules)

If this server is publicly accessible and gets pwned, they can use it as a jump box for your internal devices.

Just close 443 and use VPN with ACME DNS challenges for your certs. That’ll help make it even more secure, nothing is full proof though and a VPN is a good first step

Only if you hook up a torrent client. There’s no requirement to do so
