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

Give That Client a MAC Address based DHCP Reservation,

With your DNS Values.
