Run esp8266 in PPP server mode

[XeGhostX]

Hi, I am trying to run esp8266 in PPP server mode. At the moment I have assembled a firmware capable of establishing a PPP connection with another device using the PPP protocol used in the lwip library. However, at the moment it is not possible to transfer traffic between two WIFI and PPP networks. Tell me, in which direction is it better to go in order not to violate the current concept of IDF? As I understand the tcpip_adapter component is responsible for routing traffic in the current version of the SDK, how can I add the ppp network interface to this component so that it is less painless?

I am using the latest SDK version: ESP8266_RTOS_SDK Release v3.1

Perhaps there will be other recommendations.
Best regards, Dmitry.
