Turn off dissection of the GTP T-PDUs, then you will be able to filter to the "outer" IP address.
For this purpose, go Edit -> Preferences -> Protocols -> GTP and uncheck "Dissect T-PDU".
cheers,

Subject: [Wireshark-users] Tshark - GTP problem

I am trying to filter conversation statistics for headers above GTP using: -q -z conv,udp . But tshark seems to give stats about the headers in GTP payload. I mean not only do I get udp conversation stats of hosts above GTP, but also of those in the payload of GTP. how can I distinguish/filter the two out ?
