[srsran-users] ZMQ Open5gS 5G End-to-End - No GUTI allocated error

[Edward Colbert]

Hi,


I have ZMQ with 5G srsenb and srsue running on one LXC container, and
Open5gS running on another container, otherwise the same configuration as
the application note for 5G SA end-to-end with ZMQ.  I am running into an
error (see AMF log below).  The UE attaches and provides an IP address, but
I cannot ping from Open5gs, or in the other direction with ip netns exec. I
can't figure out what else to change.  I attach my config files here in a
ZIP file.  Any ideas?


Thanks

Ed Colbert
