Hi @abousselmi

Sorry , I accidentally closed this issue .
I am currenlty following this documentation for deploying eBPF based UPF with free5gc core.
I have been using the Docker Compose method for deployment as the k8s method doesn't seem to be working for now. Everything seems to be functioning correctly in the Docker Compose setup, as all the containers are up and running, and I've successfully tested the EUPF .

Specifically, there are two containers running for EUPF: one for Swagger and the other for Core Manager. Here are some screenshots for reference:

my eupf is sending proper heartbeats to smf

The issue arises after the establishment of PDU session and execute the following ping command within the container:

ping -I uesimtun0 google.com

Unfortunately, I'm experiencing 100% packet loss, and there is no response to the ping request.

I have attached the logs of the AMF for your reference: AMF.txt.
Also, please checkout the images in the last message too.

I would greatly appreciate any assistance or insights into why there is no response to the ping command request. Thank you!

Hi @Khushi798

Please take a look at #28 and #35

Hi @abousselmi

I have also set the iptable with

 sudo sysctl -w net.ipv4.ip_forward=1
 sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
 sudo systemctl stop ufw
 sudo iptables -I FORWARD 1 -j ACCEPT

I have also tried #28 , it is still not working.

And the output for ICMP packets are reaching the UPF using tcpdump:

Thank you!

And the output for ICMP packets are reaching the UPF using tcpdump

As per your figure, the tcpdump was executed in the UERANSIM container, not in the UPF.

You should at least be able to see the packets leaving the ueransim container's uesimtun0 (icmp) or eth0 (icmp over gtp).

Hi @Khushi798

It seems like there is no traffic leaving from uesimtun interface.
Could you please help to provide the control plane traffic inside the ueransim container?

Thanks.
