Specifying the N9 IP addresses in the configuration!



I’ve been using free5gc v3.0.4 and UERANSIM v2.2.1 inside docker containers and I was able to test successfully ping from UE when ULCL feature is enabled or disabled. When ULCL enabled, I’ve been specifying 2 routes to 2 different hosts from my data network and all works as expected. Otherwise, when I try to ping another address (e.g. www.google.com) the traffic goes always through the UPF1. Is that the expected behavior.

I’ve another question about N9 interfaces. Should they be different from the N3 interfaces? And is there any way to specify them in the free5gc configuration?
