Hi,
so....whos breaking the RFCs with respect to ICMP and pmtu? ;-)
I've been hunting one such case recently. Just in case it helps: in our case it was a BSD firewall that was misconfigured to only allow non-fragmented UDP packets. I'm not into BSD at all, the guy said something about this being a default setting? I hope I got him wrong back then. We also currently have a pending issue with Cisco WLAN Controllers. We suspect that it will take the EAPoL message from the client, and put the beginning of it into a UDP packet, simply forgetting about the rest if EAPoL payload > largest possible EAP-Message payload. We couldn't get our hands on a 100% positive test case, so didn't approach TAC yet. If any of the two are the case for you, please report back here - it's quite an interesting piece of info...
