RE: [lwip-users] Programmatically disable ICMP echo reply

[Bettega Stefano]

Hi Kieran,
LWIP_ICMP will disable echo reply but only at compile time.
I was wondering if there is a way to enable or disable it in real time.

A simple way to do it could be using a global variable, (int g_EnablePing =
1)
and testing in icmp.c for its value before answering to a echo request. But
this would require a modification of lwip source code.

Is there a better way to do so, maybe already defined in the source code?
I haven't found it yet.

Any other opinion?

Thanks,
Stefano

The closest is to define LWIP_ICMP to 0.  This is stop all ICMP
processing rather than just preventing echo replies though.
