I’m just a novice at self hosting and I see a lot of talk about the risks of exposing stuff to the world. Here’s my setup:
-Rpi4 hosting Overseerr
-Desktop computer hosting Nginx and some Cloudflare DDNS update containers
Cloudflare directs request.domain.com to my home IP address. Nginx forces HTTPS and directs the request to the Pi.
Is there any risk in this setup or are there more steps I can take to secure it?
Since you’re using cloudflare already you could utilize their cloudflare tunnel feature, that way you don’t need DDNS or any open ports, and your home IP will be hidden.
I would rather just making a wireguard vpn and having control of my data, but privacy might not be his concern.
Cloudflare tunnels also do custom certs if you wanted to maintain some amount of privacy.
Ah yes cloudflare: MITM as a service.
It really depends on who your adversaries are that you want to keep private. The coffee shop owner + their ISP + your ISP, or cloudflare. Seeing as cloudflare MITMs an insane amount of the internet these days I’m way more suspicious of them than I am of the alternative. If you’re really after privacy I’d recommend self hosting wireguard or something.
Of course, that’s why I said some resemblance of privacy - it’s still more secure (and possibly more private) than just opening ports.
For public access you would need a VPS somewhere to act as an ingress point, so that might be more than OP wants to deal with.
