Ping response produces ? unknow packet type randomly
In this situation I am not sure that the ? represents an unknown packet type. On ASA the ? is a failed/time out ping attempt.
In my experience when you attempt ping sometimes the first ping request will fail and the other work (which is the pattern shown in this post). Frequently the explanation for this is that the firewall needed to arp when it attempted the first ping and the first ping times out. After that there is an entry in the arp table and the other pings succeed. I wonder if that is what is going on here.
