I am trying to capture PMTU Disovery using ping on a Windows client as below
ping >ip addrerss> -f -l 1480
The above command will return "Packet needs to be fragmented but DF set" (as I expected). However in the Wireshark trace I can not see this packet, I would expect to see a destination host unreachable ICMP packet
When I do a ping without the fragemented packet, I can see the ICMP capture in Wireshark.
Am I correct in thinking a firewall/router etc is dropping the ICMP packet hence not in the trace file
