 The Raspberry Pi Foundation releases a special version of Debian Linux optimized for the Pi called [Raspbian](http://www.raspbian.org/). A $35 Linux computer is hard to beat. Here's a step-by-step guide for how I turned my Raspberry Pi into a geospoofing VPN gateway.
 
 Setting up the Raspberry Pi
-===========================

 First you need to start with a fresh install of Raspian "wheezy." You can download it [here](http://www.raspberrypi.org/downloads) and find a guide for writing the image to an SD card [here](http://elinux.org/RPi_Easy_SD_Card_Setup).

 The upgrade command will take quite a while though, so you might want to kick it off at night before you go to bed or before you go to work in the morning. I don't have the kind of patience to sit around and wait for something like that to finish :)

 Now that you have VPN software set up, the next step is to turn the Pi into a router. You can do this using the Linux utility, [`iptables`](http://wiki.debian.org/iptables).

 If everything was done correctly, you should now be able to use the Raspberry Pi as a VPN gateway. On another computer on the same local network, visit [WhatIsMyIPAddress.com](http://whatismyipaddress.com/). Note your current IP address and physical location on the map.

 Now all you have to do is set the router (or gateway) on your closed devices like AppleTV and Xbox 360 to the Raspberry Pi's IP address and you can access content available only in your VPN's location.
 
 Using the gateway selectively

 PrivateTunnel is priced relatively easily, but if you're doing things like streaming video, it's really easy to eat up your data transfer allotment very quickly. Luckily many services use only a single authentication request to determine your location. If you find this to be the case with your service, you can edit your OpenVPN configuration to only send requests to certain IP addresses through the VPN instead of all of them.
