Block Google DNS on DD-WRT Routers

If you have a router with the DD-WRT firmware, then you can follow this guide to use the playmoTV DNS on your router and block Google's DNS servers. This guide is provided as is,  and is meant for advanced users (if you installed the DD-WRT firmware yourself, it goes without saying that you are probably an advanced user).

Step 1: Access the web-based setup page of your router (by visiting http://192.168.1.1 or http://192.168.0.1 in your browser). Default username is admin and the default password is admin.

Step 2: Go to Setup > Basic Setup > Network Setup > Network Address Server Settings (DHCP). Choose two DNS servers of your choice from the playmoTV dashboard and set them as your DNS servers.

Step 3: Click Apply settings and continue.

Step 4: Go to Administration > Commands and enter these rules in the Commands field:

iptables -I FORWARD -d 8.8.8.8 -j DROP iptables -I FORWARD -d 8.8.4.4 -j DROP

Step 4: Once you have added all these rules, click Save Firewall

Step 5: Reboot your router by go to Administration > Management and click Reboot Router.
