debug Palo alto firewall rule

we maintain one PA security policy rule and give ip 192.168.0.11 to access server UTP01, the user is using ip 192.168.0.11, and he can't access the server, we can't find any security log for this. may i know how to debug this rule?

for me the quickest and easiest way (via GUI) is to edit the interzone-default rule at the bottom of your policies.

set the logging to session start.

you can then Monitor/Traffic and should see where the address 192.168.0.11 is trying to go to.

@palolili,

If you're not seeing any logs chances are the package is dropped before the security policy is evaluated (check the global counters).

Chances are also that the package isn't reaching the firewall even ... get PCAPS to make sure that the packages sent from the client are reaching the firewall interface.

Good luck !
