How can I see users hitting a certain NAT rule?

[JeffTQT]

Is this even possible? I know I can see the security rules being hit in the logs but what about the NAT rules?

Hi

You can look at the session id from the traffic logs for the session you are interesting in finding the NAT rule for and then go to the CLI and type

show session id (session id number)

and it will give you an output as below and you can look at the NAT rule that it is hitting.

admin@PA-2050> show session id 1

Session               1

        c2s flow:

                source:      192.168.86.205 [L3-Trusted]

                dst:         4.2.2.2

                proto:       17

                sport:       60968           dport:      53

                state:       INIT            type:       FLOW

                src user:    unknown

        s2c flow:

        rule                          : rule1

        session to be logged at end   : True

        session in session ager       : False

Please let us know if this helps.

Thank you

Hi,

You can use the following command as well to see the user as what rule he would hit going to a particular destination.

admin@PA-500> test nat-policy-match source 192.168.1.25 destination 4.2.2.2 destination-port 80 protocol 6

Thanks,
