DNS security license and traffic flow

MP18 — Mon, 17 Jun 2019 20:00:48 GMT

We have User where they access the Internet and traffic flow via say Corp PA

We have DNS server which is internal and the DNS traffic to Internet flows via say DMZ PA.

On PAN OS 9.0 if i get DNS license on Which PA i should get for?

As my understanding it should be for DMZ PA?

@MP18,

You only would really need it on the DMZ firewall, as your internal DNS servers would be the ones making the actual external DNS request and sending it through the DMZ firewall. This of course assumes that nothing traversing the other firewall is allowed direct communciation to external DNS servers and are stickly limited to your internal DNS servers.
