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?


They aren’t on the internet mainly.
My router (opnsense) has a wireguard server which is how I access things when out of the house.
I do have a minecraft server for my friends and I, but that VM is on its own network isolated from everything else.
