Open5GS and ZMQ (gNB + UE) setup on separate machines/hosts

[ahmadhassandebugs]

Hello,

I have a setup where Open5GS is running on one machine (M1) and ZMQ-based srsRAN gNB and srsUE on another machine (M2). Both machines are on the local network. I followed the readme file for multihost. Further, I changed the srsue_5g_zmq.yaml file and replaced the last 6 lines with network_mode: host. I also changed the SRS_UE_IP in .env to the IP address of the host running gNB and UE.

When I start the srsUE container, the UE doesn't get the IP address for some reason and RRC Release is triggered immediately. Below is a screenshot of M2 (left tab is srsGNB and right tab is srsUE). Any kind of help will be appreciated!

Thanks!

Can you please attach the env files used in the two hosts?

[ahmadhassandebugs]

Sure. Here are the environment file:

• open5gs-host-env
• srsrran-ue-host-env

Thanks for the env files. I see that UE is receiving a RRC Release. Can you please send me the F1AP, NGAP and pcap taken on open5gs machine?

Sorry for the delay. I have fixed the issue. I was using OPc instead OP in open5gs userdb config. Thanks!
