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 move laterally inside your network.
Realistically though you’re in good shape.
