Raspberry Pi VPN Router

This is a quick-and-dirty guide to setting up a Raspberry Pi as a "router on a stick" to PrivateInternetAccess VPN.

Requirements

Install Raspbian Jessie (2016-05-27-raspbian-jessie.img) to your Pi's sdcard.

Use the Raspberry Pi Configuration tool or sudo raspi-config to:

HTTP Streaming (or Chunked vs Store & Forward)

The standard way of understanding the HTTP protocol is via the request reply pattern. Each HTTP transaction consists of a finitely bounded HTTP request and a finitely bounded HTTP response.

However it's also possible for both parts of an HTTP 1.1 transaction to stream their possibly infinitely bounded data. The advantages is that the sender can send data that is beyond the sender's memory limit, and the receiver can act on

Auto WiFi detection or wifi hostpot creation during boot for RPI

Note: These are rough notes and there may be some variance as versions of raspbian get updated but should be pretty reliable as a guide.

This gist provides some instructions and config in order to have your Raspberry PI automatically connect to a roamed network, however if it fails to discover an available network it will set itself up as a wireless access point for you to connect to.
