Re: Syslog - Collecting Internal DNS

Interesting.  From what you described It sounds a little bit more like a hack, then an actual filter or setting with the Palo Alto as well.


Selecting, say, the url field for syslog won't capture internal DNS requests as they're hitting the Palo?

The way described by @RobinClayton isn't a hack. This is how it should be as the firewall also does not know the DNS names of the sources (except if you create address objects for ALL your internal systems). This information you should get where it is managed -> from your DNS server.

No, paloalto does not log the content of DNS requests. If you need this data, then the best place to get that is agsin your DNS server which you need to configure to send the DNS logs to your splunk server.

Even if the PA did see the DNS requests ( if you had the DNS servers on their own Zone or Subnet) routed through the firewall.... The PA is not goign to do anything special with the traffic.
