Hi Maddy,

presumably you are using Control Plane EPS Optimization and the non-IP payload is encapsulated in ESM data transport messages. If this is the case, uncheck the "Try to decode User Data Container as IP" option in the NAS-EPS preferences. If this is not the case, please post a pcap as suggested by @grahamb.
