If, instead, you choose to route your entire Internet traffic through the Tor network, your only option is an external router.

The Raspberry Pi (Figure 1) is ideal in this role because the hardware is cheap, and its power consumption is low. This project gained popularity as Onion Pi [1]. But, even as a Tor user, you should not rely on this solution alone for security. After all, obfuscating your IP address is only half the battle and cannot hide your identity on its own (see the "Tor Limits" box).
