If you’re interested in setting up Witopia on a DD-WRT router I found a few guides that seem to work well. You’ll need a personalvpn pro account for this to work. To make your life easier and support this awesome VPN service you really should get their buffalo router, I may order one and post up a review soon. Searching around you find a few guides but not all of them work completely so I’ll post some notes and details here to supplant them.
BIG DISCLAIMER: This is against the ToS of Witopia and you really should buy their router as it’ll save you a big headache and will likely perform better unless you have a kick ass router.
