The free5gc of v3.0.2 has been successfully installed and runs with N3IWF enabled. With a proper addressing, routing and dns configuration, the UE is able to connect to Internet via the free5gc and surfs on Internet. For example, UE can access to the wikipedia website.
However, access to some web sites such as youtube fails with messages in red shown in the free5gc. Specifically, the messages shows an error occurs in N3IWF with info “sendmsg: message too long”.
To clarify the root problem, we conducted a ping from UE to 126.96.36.199 (an IP address configured at loopback interface in the UPF namespace of the free5gc). The same error message was shown in the free5gc.
As of now, we are still trying to address the problem. It would be great if the free5gc team can figure out the problem and provide us a possible fix. Thank you so much.
