Block ping to ESP32

Postby Germanium » Sat Apr 01, 2023 8:38 pm

Hi, I'm using Esp32-C3 with ESP IDF.
I am connecting to the network via Ethernet (W5500) or WIFI.

When I connect, I don't want esp32 to be pinged.
How can I block?

Thanks

Please post back if you figure it out. Two things I found that might point you in the right direction:

Disable Menuconfig -> Component config → LWIP → ICMP -> ICMP: Enable ICMP.
