+This describes a very simple configuration that uses free5GC and UERANSIM for ULCL with one I-UPF and two PSA-UPFs.  
+**Note. According to [this](https://forum.free5gc.org/t/access-to-local-dn-through-i-upf-in-ulcl-scenario/2512/4), the ULCL feature in free5GC v3.4.0 or later versions won’t work due to the lack of forwarding parameters in FAR creation.**
