Issue setting up multi-ue #65

Closed mfuentesg2021 closed 8 months ago

mfuentesg2021 commented 8 months ago

Hello, I have tested the multi-ue feature for setting 2 different UEs with packetRusher and Open5gs core. When setting up the./packetrusher ue, there is no any issue, the attach is performed succesfully, but when setting up the multi-UE for either 1 or 2 UEs the last step of binding the valxxx interface to the assigned IP is not properly being generated for any UE. Both UEs has been configured on the open5gs database.

The configuraration config/config.yml

Hi @mfuentesg2021! Make sure to run sudo ./packetrusher multi-ue with the option --tunnel to enable tunneling with multiple UEs ;-) You'll need the --dedicatedGnb option as well, see https://github.com/HewlettPackard/PacketRusher/issues/62#issuecomment-1875382929 for more information on how multiple gNodeB are handled.

Hi @mfuentesg2021, I'm closing the issue, feel free to reopen it if you are still having troubles! Cheers, Valentin
