Is it safe to open ports 80 and 443 in my home network? (sh.itjust.works)

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!

Forwarding a port only forwards traffic to the device you specify. Be prepared for plenty of port scans though. If you have internal system email set up your Fail2Ban will be sending you daily messages. I get 5 or 6 a day from automated port scans triggering Fail2Ban.
