did you manage to solve it ?

#3

Since my UPF, GNB and UE are placed in another virtual machine, I need to modify the N3 in the SMF configuration file to be the IP of the UPF virtual machine, the N2 in AMF to be the IP of the virtual machine where UPF is located, the GTPU in UPF to be the IP of the local machine, and everything else remains the same, so I can adjust it.
