esp8266 webserver IOT

Hello friends. I recently bought the esp8266 module and wanted to implement a web server. I want to access the esp and Arduino connected to it from anywhere. I used NAT and port forwarding . The html script uses php.I work with the get statement to send info to the url(router) so it can be sent to the esp connected to this router. Everything works inside the lan, but if I try to send info from the internet(from a device which is not connected to the same network as the esp), it does not work.

Anyone knows something about it?

Thanks:)
