I am searching for a WiFi repeater example in Arduino. The lwip2 has been implemented in ESP8266 Arduino and it supports NAT routing but I couldn't find any examples for that. How to use lwip2 lib in Arduino?

The closest thing out there that I know of is this project:
https://github.com/martin-ger/esp_wifi_repeater

Quite a nice little project!

From the same author:

*** This lib is somewhat obsolete because of the recent update of ESP8266 Arduino https://github.com/esp8266/Arduino. With this update in the master branch, the lwip2 implementiation also supports NAT routing. If you need this feature you might want to consider this option. ***

Probably this https://github.com/esp8266/Arduino/tree ... ender-NAPT is the right way...
