Is it safe to open ports 80 and 443 in my home network? (self.selfhosted)

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 port forward to your Pi, only your Pi will be exposed. But, if your Pi gets pwned, it can in turn attack anything next to it. Safest is to isolate the Pi on it's own subnet or a DMZ if your router has the functionality.

Of note, many home ISPs block standard server ports like 80 and 443. You might need to use non standard ports like 8080 and 8443
