UE unable to ping

[jy11-2]

Hi! I was facing the issue below, would really appreciate some help. Thanks!!!

Environment
Ubuntu: 20.04-Focal
Docker version: 24.0.7
Docker compose version: 2.21.0
Kernel-release: 5.4.0-167-generic
Loaded Kernel module : gtp5g 0.8.3

Deployment status:

Free5GC and UERANSIM were deployed in a single host machine both using docker-compose version.

IP address for all containers:

In order to bring up UE only after setting up gNB and webconsole, I made the following modifications in docker-compose-build.yaml and docker-compose.yaml:

1. Separate ueransim container into 2 containers: ue and gnb
2. Container ue depends on container gnb
3. After running docker compose -f docker-compose-build.yaml up , I run docker stop ue and log into webconsole to add in subscriber. Then run docker restart ue.

docker-compose-build.yaml

docker-compose.yaml

Could someone give me some advice if this deployment is fine?

Configuration

[amfcfg.yaml]

[smfcfg.yaml]

[nrfcfg.yaml]

[upfcfg.yaml]

[gnbcfg.yaml]

I've modified the linkIp as gnb.free5gc.org, which was originally 127.0.0.1

Others remained unchanged

[uecfg.yaml]

I've modified OP type as OP, and gNBSearchList as gnb.free5gc.org, which was originally 127.0.0.1

Current behaviour

ping -I uesimtun0 command ran inside the ue container is not receiving any ICMP reply as expected with 100% packet loss.

I have monitored necessary interfaces:

[UPF: eth0] No packets observed

[UPF:upfgtp] No packets observed

Verifying if upfgtp interface is assigned an IP address => no IP address is assigned to the upfgtp interface. I really appreciate it if someone can guide me towards verifying the reason for this.

[UPF routing table]

Applying the changes suggested by #28 does not fix the issue nor changed the above reported outputs

[UE: uesimtun tcpdump] : No packets observed

[UE: eth0 tcpdump]: Packets can be observed as per normal

[UE routing table]

Logs

I'm a fresh starter in 5g technologies and still have a lot to learn. Hoping someone can give me some advice on how to solve this issue, thank you so much!!!
