And you have re-enabled PMTU yes?

 

Now PMTU is enabled, customer didn't want to disable cause it'll affect other virtual server.

 

you do see it in tcpdump, don't you? have you provided support the tcdpump? it is C1263209, isn't it? what is the tcpdump filename?

Yes I do, I provide file in C1263209 which name is tcpdumpfiles.tar.gz (extract and take a look in mt-0110-1000.pcap (01/10/2012 time 10.00)) .
