Dear ,
I was following the tesh.sh script , and i saw that we are running all the components such as UPF, runCN, N3IWF, then UE is getting started to run.
now my question is how this UE would be able to ping the Data network i.e, google.com in my case.
Thanks
vikash
You might modify the ping IP inside src/test/registration_test.go
Thanks a lot. I will look into it.
Dear,
i am getting the below error when i am running $ ./test.sh TestRegistration

It seems similar issue to the one below.
Did you make a modification on the configuration?
Dear,
No, I didn’t modify any configurations. i can see only this “TestNon3GPP” Test is getting passed, others are getting failed.
My ngapIpList is blow:

Can you please test again by replacing the command git.cs.nctu.edu.tw/calee/sctp to github.com/ishidawataru/sctp and check whether the issue will be resolve.
What is the error message?
if the error is similar to the one above, you can try it again by replacing this command git.cs.nctu.edu.tw/calee/sctp to github.com/ishidawataru/sctp.
I tried to replace sctp as per your instruction but still problem not got resolved.
hi,
if you are familiar with the oneinall OAI project,you can setup a local site connectivity like that.then use run.sh(do a little change),and change the connectivity data in test.sh. and modify the registration_test.go .
and add the snat use iptables. i have made it work. In real world,the 5gc shall run separate,and connect with gnb.

br，thornton.
Try this solution
Dear thornton,
Are you using RFSIMULATOR provided by OAI to set up the communication with free5GC?
hi.
i use the test script(but i didn’t use the netns),you can change the destination of ping in the registration_test.go. and the most important is the iptables(you can do it by snat, your UE ip to your Gi interface).
br,thornton.
Hi bro,
I check this topic and only find the .pcap file attached. Would you pls upload the pdf instruction again? I think what you’ve done can be a great help for newbie like me. I am quite struggle in the setup procedure. So many thanks.
Hi bro,
Thanks so much!!!
Dear @thornton
Thanks for the PDF instruction!
I don’t know what gi addres in instruction means.
Is the gi address some kind of IP address assigned to the UPF by free5GC?
How can I find the gi address?
hi
it’s the interface to connect to internet.
br,thornton.
Hi @thornton.
In other words, is the gi address the IP address associated with wlp2s0, which is set to natifname in instruction?
