what you have is a webserver on your ?PC? what can be called with its local IP from within the network
correct?

if you want to call that webserver from the “outside” internet

  • -a- you need to know the IP of your home router( browser check my ip )

  • -b- when you then contact your router from outside it must know that you want to talk to the local PC with the local IP you see from the processing.

    • -b1- well there can only be one server in your network ( on port 80 why you changed that, pls go back to use old port again )
    • -b2- in the router configure a port forward to the local ip of your server (PC). if use port other then 80 pls configure that there too.
    • -b3- and now need lots of luck that your ISP allow that, (any server from your home / they might want sell you fix ip service… )

  • -c- testing can be difficult , so its good to be “outside” like with some free internet tools ( VPN and proxy service ) so you can call back your home, because also your router might not allow to talk from inside via outside to inside …
