Hi all, I’m running a small website off of a raspberry pi in my house. I have opened ports 80 and 443 and connected my IP to a domain. I’m pretty confident in my security for my raspberry pi (no password ssh, fail2ban, nginx. Shoutout networkchuck.). However, I am wondering if by exposing my ports to the raspberry pi, I am also exposing those same ports to other devices in my home network, for example, my PC. I’m just a bit unsure if port forwarding to an internal IP would also expose other internal IP’s or if it only goes to the pi. If you are able to answer or have any other comments about my setup, I would appreciate your comment. Thanks!
The port forward only forwards to a single device so you aren’t exposing your PC (directly anyway). Sounds like you have the pi good and secured but if you wanted to add another layer you could segment it out into a DMZ or its own VLAN. That way if something did happen with it an attacker couldn’t more laterally inside your network.
I have my services proxied through nginx and behind cloudflares free tier. That way I don’t have to worry about my IP getting exposed and opening myself up to DDOS/DOS attacks, which is a genuine threat if you do things that piss people off (I’m an admin on a popular minecraft server).
I looked into nginx for minecraft, but minecraft doesn’t use http headers, so I’d have to open minecraft ports on the router. Would this alleviate that? What’s the difference between this setup and using something like a cloudflare tunnel? Obviously, there is still some reliance on Cloudflare.

Realistically though you’re in good shape.
