-  | 3 | Local dashboards  | In some scenarios, the local dashboards don't show session rejection under the **Device and Session Statistics** panel if Session Establishment requests are rejected due to invalid PDU type (e.g. IPv6 when only IPv4 supported).   | 
-  | 4 | Packet forwarding  | When Azure Private 5G Core has NAT enabled on a data network, approximately one in every 65,536 downlink packets sent to a UE will be emitted with an incorrect IP checksum, which will likely cause it to be dropped.  |
