Hello Vsingh, You may follow below mentioned troubleshooting steps to narrow down the problem: Please check the real time session in the CLI by using 'show session all filter source IP_ADD_OF_THE_TESTING_PC destination IP_ADD_OF_THE_DESTINATION'. > If there is a session exist for the same traffic, then please apply CLI command PAN> show session id XYZ >>>>>>>> to get detailed information about that session, i.e NAT rule, security rule, ingress/egress interface etc. > verify the global counters, if a specific "DRP" counter is increasing rapidly. The command show counter global provides information about the processes/actions taken on the packets going through the device; if they are dropped, nat-ed, decrypted etc. ( It is advised to use the command show counter global filter packet-filter yes delta yes in conjunction with filters to obtain meaningful data.) For more information, you can follow the DOC What is the Significance of Global Counters? Packet Capture, Debug Flow-basic and Counter Commands Hope this helps. Thanks
