Inspired by this comment to try to learn what I'm missing.

Cloudflare proxy
Reverse Proxy
Fail2ban
Docker containers on their own networks

Another concern I have is does it need to be on a separate machine on a vlan from the rest of the network or is that too much?

Fail2ban config can get fairly involved in my experience. I'm probably not doing it the right way, as I wrote a bunch of web server ban rules

anyone trying to access wpadmin gets banned, for instance (I don't use WordPress, and if I did, it wouldn't be accessible from my public facing reverse proxy).

I just skimmed my nginx logs and looked for anything funky and put that in a ban rule, basically.

Thanks!

Here’s the setup I followed. It seems like it might take away some manual work for you: https://m.youtube.com/watch?v=Ha8NIAOsNvo&t=1294s&pp=ygUIRmFpbDJiYW4%3D
