Hi, @s5uishida
Sorry I gave the worng information that my free5GC version is v3.2.0, and I found that our go version is different. Is it possible that error is cased by the versions not support or other reasion? Thanks.
Hi @sing1020
I was able to get the latest versions of free5GC and gtp5g installed and working by following the steps below.
https://github.com/free5gc/free5gc/wiki/Installation
For earlier versions, I think it probably works, but I'm not sure.
Hi @s5uishida
OK, I'll try it. If it works due to the different versions, I would let you know:)
Thanks.
Hi @s5uishida
It works in my environment.
And I found the reason for the error is that I stupidly gave the wrong IP address of the DNN... I'm going to create rest of it, thanks.
Hi @sing1020
I don't understand why you set the CIDR as that way for DNN=internet and internet2.
For your reference, my upfcfg.yaml
is as follows.
~/free5gc/config/upfcfg.yaml
version: 1.0.3
description: UPF initial local configuration

Hi @s5uishida
I set the NIC as NAT in VM so that the CIDR can access to internet(DN).
If I set NIC as other options, it can't access to internet(DN).
If it's not correct, what should I do...? Now I got the same error in U-Plane2...
Thanks
Hi @sing1020
I use bridged mode for my VM's networking, but you can also select NAT networking. (In a way that works for you.)
However, the DN's network must be a different network than the VM's private network.
As for the network, I think you may configure it according to each environment.
Hi @s5uishida
Ok, I'll try it. Thanks for your advice~:)
Hi @s5uishida
Sorry to bother you again... I changed to use bridged mode for VM's networking, and the UPF1, UPF2, gNB were working well. But I got errors when start up C-Plane, it seem to affect subsequent UE startup errors.
C-Plane's error when start up
gNB start up and the reaction of C-Plane gNB: C-Plane:
UE start up and the reaction of C-Plane UE: C-Plane:
I had check the smfcfg.yaml that seem correct and I set the network setting of U-Plan1 and U-Plane2 before startup. Do you think this error is caused by my smfcfg.yaml file is not set properly or there are other reasons? Below link is my smfcfg.yaml file. Any suggestions or helps are appreciated:) Thanks.
Hi @sing1020
As shown in the error log on the first screen, the following lines in smfcfg.yaml contain tabs.
- dnn: ims
dns:
ipv4: 8.8.8.8
Hi @s5uishida
OK... I'll fix it and keep creating. Thanks. :)
Hi @s5uishida
I did creat uesimtun0~2 as below with bridge mode. uesimtun0 -> internet uesimtun1 -> internet2 uesimtun2 -> ims
But the uesimtun0~2 can't ping to goole.com due to my bridge mode can't access to internet... When I changed it to NAT mode which can access to internet, the C-Plane would show "[FATA][SMF][Init] overlap cidr value between UPFs", then UE failed to connect.
I still don't understand how to make the IP addresses(or CIDR) correct that can access to internet and make uesimtun ping to google.com...
Could you show the network setting of /etc/netplan/00-installer-config.yaml or give informations that can help me to figure it out?
Thanks.
Have you registered UEs in core network in webconsole? also, set the "Data Network Name" as "ims"?
I have problem... connecting to goole.com as well.... All the things set up well, core network, two UPFs, gNB and UEs. Besides, in two UPFs VM, set iptables. However, when I type "ping -I ueransim0 google.com" , it does not work...
Hi, @s5uishida I tried to create the One SMF, Multiple UPFs and DNNs of your Sample Configurations and followed the steps. When I tried to run the free5GC U-Plan1, I got the error.
Have you ever had the same problem? Any suggestions or helps are appreciated:)
Linux version: ubuntu-20.04.5-live-server-amd64 free5GC version: v3.2.1
Thanks.
