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!

You’ll be ok as long as whatever software you’re running that is listening to 80 and 443 never has an exploitable vulnerability, if it does… you may be in trouble depending on the vulnerability.

Or be careful of the service on the other side of your (I assume) reverse proxy, should it have a vulnerability you may still be in trouble depending on the setup of the reverse proxy and what it’s config is.
