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!

    DMZ in essence means “forward ALL ports” to X. You should only DMZ a host that you know is very secure as its attack surface is significantly increased. If you need just one or two services open, best to not use DMZ
