Hello Niuk, You can 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 an 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. These counters are for all the traffic going through the device and are useful in troubleshooting issues; like poor performance, packet loss, latency 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? > You can enable FLOW BASIC feature to understand the exact reason behind the failure: > debug dataplane packet-diag clear all > debug dataplane packet-diag set filter match source IP_ADD_OF_THE_TESTING_PC destination IP_ADD_OF_THE_DESTINATION > debug dataplane packet-diag set filter match source IP_ADD_OF_THE_DESTINATION destination IP_ADD_OF_THE_TESTING_PC > debug dataplane packet-diag set log feature flow basic > debug dataplane packet-diag set log feature tcp all > debug dataplane packet-diag set filter on > debug dataplane packet-diag set log on ~~~~~~~~~~~~~~~~ Initiate traffic ( try to access the management interface) ~~~~~~~~~~~~~~~~~~~~~~~~~ > debug dataplane packet-diag set log off > debug dataplane packet-diag aggregate-logs > less mp-log pan_packetdiag_log.log For more information, you can follow the DOC: Packet Capture, Debug Flow-basic and Counter Commands Hope this helps.
