Hi, I met the same problem, Here are the logs of the ue and gnb This is the log for upf From the log, it seems everything is connected, but I has the same problem here. I guess it mainly because I applied the open5gs and ueransim in the same machine, so I will change to use two machines. But I am open to the other solutions :)

@MMMMMMorty If you run core network sim and ueransim on the same machine, it is impossible to route the packets to your data network. I'd say you need to implement it on two different machines or VMs and check the guide at https://open5gs.org/open5gs/docs/guide/01-quickstart/ specifically the "Adding a route for the UE to have WAN connectivity"
