You can do packet capture in GUI with apropriate filters and look at what is cpatured in drop stage of processing.
You can also monitor global counters, but here you will just see counter increasing and not which packet was actually dropped.
show counter global name tcp_drop_packet
And if you want to turn off asymetric check on WHOLE PA appliance for all zones:
set deviceconfig setting tcp asymmetric-path bypass
But if i understand correctly you already did that?
Please check out this article regarding packetcaptures :) Getting Started: Packet Capture
Please be very careful with the asymmetric-path configuration as it could open up unexpected avenues of attack : sessions bypassed this way will not be L4-L7 scanned by appID/contentID and could contain malicious payload you will not be able to identify, this setting is global so could also impact packets coming from untrusted networks.
For more information regarding the impact of the setting: Palo Alto Networks TCP Settings and Counters
I thought about it and i came to the conclusion that the Palo is slow already as it is, if i even am to add a NAT to translate WITHIN the LAN every packet to another internal segment, it will catch fire.
I found an article that explains how to create a zone protection and i will apply on the trust zone only so to avoid enabling the bypass globally, and in the zone protection to avoid dropping traffic because of the syn sequential number problem
thanks to all pointing in the right direction
also, any latency you might experience is purely the management plane, the dataplane has it's own set of cpu/memory/... and is quite fast
you can check available resources for both planes with these commands:
Dataplane > show running resource-monitor Managementplane > show system resources
please consider going with the NAT option, I promise your firewall won't catch fire :)
