Personal Onion Router To Assure Liberty

Overview

PORTAL is a project that aims to keep people out of jail. It is a dedicated hardware device (a router) which forces all internet traffic to be sent over the Tor network. This significantly increases the odds of using Tor effectively, and reduces the potential to make fatal mistakes.

On Hardware

There are two ways to construct a PORTAL: using a chipped router (recommended), or using "the /overlay trick". Using a modified router (with sufficient onboard flash) provides the most flexibility for internet connectivity (either WiFi or 3G) as well as ensuring that the Tor process has sufficient RAM to run. A chipped router provides the best overall experience. The /overlay trick enables a stock router to union mount a microSD card for additional storage space. This allows for multiple microSD cards to provide different configurations (also possible with a chipped router), but has the downside of requiring a 3G modem with onboard microSD slot.

Supported Devices

Chipped Routers

Stock Routers

It is highly recommended to use a modified router. The modified MR11U and WR703N provide a better experience than the stock routers due to the additional RAM. The severe space constraints of the stock router make them very challenging to work with. Due to the lack of usable space, it is necessary to use an external disk to store the Tor packages. The stock router has only a single USB port, and the best option is to use a microSD in a 3G modem.
