I would to use my ESP8266 as an access point and use the station's internet connection
I can do the AP with:
AT+CWSAP="esp_123","1234test",5,3

Then I connect to it with my iPhone. I change the settings Configure IP to Manual, set the IP and mask and leave blank Router. With this way I have cellular internet connection while I am connected to the ESP8266.

But now I would like to connect from ESP8266 to the web like:
AT+CIPSTART="TCP","1.2.3.4",80

But it is not working.

What settings needs to be done?

Thanks!
