Hi all,
There is a demo about forwarding data between ethernet and softap, the link is https://github.com/espressif/esp-iot-so ... s/eth2wifi. Maybe it is helpful for you.

Hi,

For L2 forward between WiFi and Ethernet, please refer to: https://github.com/espressif/esp-iot-so ... s/eth2wifi

For L3 forward between WiFi and Ethernet, I think the LWIP ip forward can work correctly without any change if the network topology is simple enough,

For example, as following picture described:
1. Two stations (PC and phone) are connected to ESP32 AP, the ip address is 192.168.4.2 and 192.168.4.3 respectively
2. Ethernet connects to the external device, the IP is 10.10.10.10.
3. If PC, phone, external device (extern AP) know each others IP address, then they can communicate with each via IP address
