So I wanted a VPN this weekend for working from coffee shops and the like. I found a good recipe for a PPTP install and set it up on an EC2 Micro, which happens to fall in the free tier. Free VPN!
During the process I went ahead and turned it into a script. It only takes a few seconds to run and will set you up for good.
Ther are side effects to this script. If you have made any changes to /etc/rc.local they will get removed, sorry. On a fresh install it will be fine.
