How to port forward for a nginx server running on a raspberry pi
I have an Nginx web server running on a raspberry pi zero w, with which I interface through ssh from my main windows 10 pc.
I have heard that if I want someone to connect to the website on the server, I don’t need to buy a domain, I just need to port forward and do some IP trickery to get a usable address that I can send to my friends, is this true? If so, can you point me in the direction of a tutorial or forum that can tell me how to do this? i have tried to find a way on my own and got nowhere.
