There is no need to change any settings on your device. You can simply use the IP tables under the advanced menu option to configure your routing. If you can configure the DNS settings on your media device (PS3 for example) then rather do that but some devices like the Roku dont allow you to configur the primary and secondary DNS servers that UnoTelly provides. The easiest way is to get the mac address for your media player and use the following script. It's simply and doesnt mess with any Bitco settings on the router.
Copy the following text, replace the XX:XX:XX:XX:XX:XX with your device mac address and follow instructions. Merry Christmas all.
# PASTE THE BELOW SCRIPTS INTO ADMINISTRATION -> SCRIPTS -> FIREWALL (LINKSYS E900).
# REPLACE THE MAC ADDRESS (XX:XX:XX:XX:XX:XX) WITH THE MAC ADDRESS OF YOUR DEVICE.
# REBOOT ROUTER.
# DROP PACKETS SENT TO THE FOLLOWING IP ADDRESSES FROM THE SPECIFIED MAC ADDRESSES.
# THIS IS REQUIRED FOR DEVICES THAT USE GOOGLE DNS TO RESOLVE LOCATION E.G. ROKU.
# THIS WILL PREVENT DEVICES LIKE THE ROKU FROM CHECKING GOOGLE FOR YOUR LOCATION
