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!
I did this for some time. But now I don’t want any ports open at home.
That’s why I have a rented VPS that runs Traefik (a reverse proxy). This VPS has a VPN connection to my home net and is behind Cloudflare DNS. This is how I can safely expose services (even in my home net) to the Internet without forwarding any ports.
Of course those services need to have some kind of authentication.
