Below is my uerouting.yaml file
ueRoutingInfo: # the list of UE routing information
SUPI: imsi-208930000000003 # Subscription Permanent Identifier of the UE
AN: 10.200.200.101 # the IP address of RAN
PathList: # the pre-config paths for this SUPI
At the UE, ping works perfectly fine. when I ping google.com (172.217.160.206), traffic flows through UPF2. and when I ping youtube.com (142.250.183.110), the traffic flows through UPF1. As expected.
But when I use nr-binder from UERANSIM to bind all traffic from firefox through the ue, I am not able to access google.com or youtube.com.
Can you please help me understand what could be the potential problem?
Hi @s5uishida,
Thank you for your help!
I tried this $ xhost +local:
Then switch to root with sudo, and run the following to start firefox,
# export DISPLAY=:0
# sh nr-binder 60.60.0.1 firefox
But I got the following error: Running Firefox as root in a regular user's session is not supported. ($XAUTHORITY is /run/user/1000/gdm/Xauthority which is owned by manoj.)
And then i googled this error, and followed instructions from here:
And I got the firefox running as a root using the following command XAUTHORITY=/root/Xauthority sudo sh nr-binder 60.60.0.2 firefox
and firefox opened
but still, I get the same error message when I try to access google dot com
below is the screenshot:
First, for browsing that www.google.com with firefox, did the upfgtp tcpdump packets on each Anchor-UPF pass the path you expected? (about this packet that reached www.google.com and resulted in an error)
If so, the ULCL probably seems OK. I think that Secure Connection Failed of firefox is a different issue from ULCL setting.
Hi @s5uishida,
The packets go to each anchor-upf pass the expected path. But I cannot access the website on firefox.
I suspect the data is failing the security checks due to incorrect proxy settings. My concern is though, How is the ULCL supposed to work in the real world? If it does not allow browsing of websites? or are there additional things to be implemented for such browsing that are not yet implemented in the free5gc UPF yet?
Thanks a lot again for all the help

Hi @calee,
Thank you for your suggestion!! and Sorry for the late reply.
I don’t think it’s the issue of MTU’s because wget for large files also works without any problem.
But yet, I tried limiting the MTU for the VM running the UE and increased the MTUs of the VM’s running the UPFs. Yet I have the same problem.(Am I doing anything wrong with these MTUs, please let me know)
I am guessing it might have to do with the secure handshakes when loading an HTTPS website and browser failing to verify the authentication of packets(I am no expert here, guessing based on a lot of googling).
Any insight/help regarding this is much appreciated.
Thanks,
Manoj
