Hello folks,

i've a bit strange issue in the communication between a Server and his
client (a microcontroler).
The controler send "Echo Reply" packets without a corresponding ICMP requests. Is there another way how this can happen then an program or firmware error? Something like an TCP packet that requests a ICMP Echo 
par example?

Hi Micheal!

Is it only the ICMP packets or other packets as well that you don't see?
Make sure you that you can capture both directions of the conversation, as it could be a capture interface problem.
