Hi,

Does anyone know why in the ICMP::CopyICMPMessage call in
ICMP::BuildICMPMessage, the last parameter is the length of the IP header,
not the length of the IP packet? It was always my understanding the ICMP
packet should fit as much of the IP packet causing the exception, not just
the header. Also when the checksum is calculated for IP, the parameters
would cover the header only, not the whole packet.

Any ideas?

Thanks,
Bassem
