Block outgoing DNS connections to Google Public DNS

Hi,

Please find my config of my Cisco 877 attached. Can someone provide me with the commands that will only allow outgoing DNS connections to the following IP addresses below. I have a user bypassing my DNS content filtering by using Google's public DNS servers. Thank you

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Give That Client a MAC Address based DHCP Reservation,

With your DNS Values.
