We just have deployed the free5gc in our cloud and finish the test case. Now we need to connect commercial RAN. In the config file， we can see some configrations such as ipaddress/PLMN,but we do not find vpn configration item in AMF N2 （in commercial network
we planning vpn to the RAN），do you have full configration to any external RAN and DN for N2/N3/N6 ？
There is no feature of VPN on N2 interface in free5GC.
We’re not sure if there is any VPN feature in 5G core network in 3GPP.
