This tutorial will show you how to use your Raspberry Pi as a WiFi access point that blocks ads by default for any devices using it. This is really neat in that it would work for your Android or iOS device, your Xbox 360, TiVo, laptop, and more without needing to customize any of those devices other than to use your Raspberry Pi as the access point for WiFi. Using an ad-blocker can be useful for conserving bandwidth, helping out low-power devices, or for keeping your sanity while browsing the web!

I do suggest whitelisting your favorite ad-supported sites so that you can continue to support them (this tutorial shows how to do this as well).

It's not easy keeping up with those wily ad serving companies so we'll also setup a way to keep your ad blocking lists up to date as part of this tutorial.

I used many pages as inspiration in order to set this up, including, but not limited to:

• http://sfxpt.wordpress.com/2011/02/21/the-best-ad-blocking-method/
  
• http://www.debian-administration.org/article/Blocking_ad_servers_with_dnsmasq
  
• http://willitscript.com/post/39397777079/raspberry-pi-as-an-ad-blocking-server
  
• http://learn.adafruit.com/setting-up-a-raspberry-pi-as-a-wifi-access-point/overview

Each of those links contain useful information, but the next few pages will walk you through in detail each step necessary to successfully block ads with your Raspberry Pi.
