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!
If you’ve set up a VPN to your home net then why not run that VPN from the devices you use to access the reverse proxy? With wireguard at least this is quite easy.
That way you don’t have to expose anything you just run a VPN with the reverse proxy in it.
My setup is
Internet <—> Reverse Proxy (on VPS) <—> OpenVPN Server (on VPS) <—> VPN Client (home router) <—> local stuff…
I don’t understand what you mean? Generally I don’t like to require a VPN to access stuff. My use case is, when I’m away I’d like to be able to access things from e.g. a public device, a friends laptop, etc. That’s why I’m not using a VPN to access things.
The VPN site-to-site connection is mainly responsible to make network shares available on my Nextcloud instance and provide access to other (local) services via the reverse proxy
Currently I’m rethinking the VPN, but I don’t think I can ditch it in favor if e.g. Cloudflare Access tunnels (too unflexible, limited compatibility, or too much hassle to keep everything configured correctly).
Also, I don’t use VPN to authorize requests. I use Authelia to authorize users with Free-IPA as directory in the backend.
I know, this might be overkill for my “simple” use cases, but I like to play around with these kind of enterprise-adjacent solutions.
