Thanks so much for the effort srsRAN_4G team.

Expected Behavior

After attaching the srsue, I expect the ping to work.

Actual Behaviour

Ping does not work. sudo ip netns exec ue1 ping 10.45.0.1 image

Steps to reproduce the problem

[Tell us how to reproduce this issue e.g. RF setup, application config files] I follow this tutorial: https://docs.srsran.com/projects/4g/en/latest/app_notes/source/5g_sa_E2E/source/index.html

Looking at your logs I see some errors in the UPF in open5gs. I assume that this is causing the actual problem. From log_core.txt:

03/15 11:27:20.516: [upf] WARNING: PFCP[RSP] has already been associated [127.0.0.4]:8805 (../src/upf/pfcp-sm.c:213) 03/15 11:27:27.517: [sock] ERROR: ogs_write() failed (5:Input/output error) (../lib/tun/tunio.c:83)

I think fixing these issues should solve your problem.
