ESP32 Forum

Hi. I have a SIM800 modem. It has internet connection over PPPoS and it works well.

Now my goal is to config a ESP32 as AP and route traffic to PPPoS interface.
AP works and I can connect an external device to a ESP32.

The problem is: an external device says it has no internet connection when it connected to my AP.
I've switched IP_FORWARD on but unfortunately it doesn't work.

How can I implement this feature? Does someone have any examples, guides or advice?

Hi,

I believe that there is no any mechanism to provide that type of connectivity which you are thinking.

Because AP mode is for offline communication and STA mode or PPPoS is for external network connectivity. I will look into IP Forward feature into details and will let you know that it is possible or not which you are thinking.
