Ping from ueransim VM to free5gc-compose

Q/A
#1

Hi,

I created the free5gc-compose which means each NF as a container and I created the UERANSIM in a separate virtual machine.
I am able to run the UE and free5gc-compose, but I cannot run the ping while I have this tunnel
ping -I uesimtun0 google.com

Did anyone face this issue and fix it?

Thank you

@nathaliewehbe.nw, Am I seeing this correct? you are running the iptables command on UERANSIM VM. But these commands are to be run in the UPF containers.

Hi I already fix it by running iptables on upfb container level, and uncommented in the file of upfb this line natifname:eth0
