Hi all,

We are configured with our ISP's forwarders. If I add google's DNS as a forwarder and I want all external requests to go to Google's forwarder, do I do anything specific to make it happen ? Or do I just add the IP for google's DNS and move it up the order ?

Exactly like you are saying. Put it up in the order.

Thanks Ruud,

That's it ? We dont do anything else ? Is there any way to check which forwarder is being primarily used ?

Thanks for the reply.

If you want to see which forwarder or forwarders are actually being used (as opposed to the order in which they're configured to be used), a filtered packet capture is the only way I can think of to accomplish this.

You'll most likely see exactly what you would expect: all forwarded queries going to the forwarder at the top of the list. The next forwarder on the list will only be used if that one doesn't respond.
