Tngf_UE test error

Q/A
#1

Hi Developers!

I have a problem for running the experiment you kindly provided in this link.

I have done your steps. My Tngf IP is set based on the following modifications in the bridge mode (192.168.1.102)

Tngf Config

I set this IP and interface to a bridge mode with my OpenWRT router.
The OpenWRT IP is: 192.168.1.2.

I have N3iwf UE on another machine (Ubuntu 20.04).
I have attached the logs of my Free5GC core when the TngfUE tries to connect to the Core network:

The process is not terminated in the Tngf Ue and I cannot see the created tunnels to establish a ping connection.
Please kindly help me like before!

All the best,

Hi,

Could you provide the logs from both free5GC and TNGFUE? This will help us analyze the issue more effectively.

Please find attachments. TNGFUE.pcapng (21.5 KB) TNGF.pcapng (76.1 KB)

Were there any error messages in the free5GC logs? And you also need to capture traffic through loopback interface in free5GC.

Hi @AmirHossein1995,

Could you share details about the architecture you are using? Specifically, are you running your setup in Docker containers(free5gc-compose)?

I noticed that TNGFUE is not acquiring the MAC address of TNGF.

Thanks for your fast reply.

As you noticed, I am running my setup in Docker containers(free5gc-compose 3.4.4).

Please let me know if I need to share more information.

So, your free5GC run on a VM, and one of interface is bridge mode connecting the AP with IP: 192.168.1.102? How about 192.168.1.120? I found it in your TNGF pcap file. Is it your host IP?

#10

I think I made a mistake here.
Let me write all the addresses for you.

192.168.1.2 is the default gateway address of the router,
192.168.1.120 is the ipv4 address of the host,
192.168.1.102 is the address of TNGF.

Hi. Please let me know if I need to provide more information.

Sorry for the slow response.

  1. Please provide the captured logs for free5GC, including the communication packets between NFs.
    Example:

  2. Verify that 192.168.1.102 is the IP address assigned to the bridge interface connected to your AP. If you are not using a VM, use the IP address directly connected to your AP instead.

HI.

Please check the attached Core_Capture.pcapng (419.6 KB) .

Also you can find the attached image.

Thank you.

Based on your screenshot, I think you should check your SQN value in sec.conf first, it should be the same as your subscriber info in webconsole.

Hi. Thank you very much

My TNGFUE goes to the connected state but the final GRE tunnels cannot be created.
I have attached the latest Core_test_ff.pcapng (1.9 MB) file.

Please provide your complete NIC information for both free5GC and TNGFUE.
