Wireshark-users: Re: [Wireshark-users] analyzing icmp protocol

Hello Jaap,

I don't have the capturing in the other side (it is embedded target).
I reolve the issue, it seems to be related to checksum.
Yet, I didn't see in wireshark any warning or yello marking on the
reply checksum.

Do you know how I could easily detect that there is an ICMP reply
checksum issue with wireshark ?

Thanks,
Ran
