Hi, everyone

         My pleasure to get your attention. Someday I encountered a [DNS]
flow as follows, after pdp context activation, the ms send [DNS]request 4
times, but receive no response, and then the ms send a [ICMP] packet,
telling network destination unreachable:



 

But acturely, the [BSSGP]DL-UNITDATA underlined in the above graph is
decoded into [DNS]response in other software, as follows:



So I don't know what is the problem, the attachment is raw signal file, can
someone discuss it?

Thanks in advance!
