I would like to set up VPN on my 2600V but don't know what I need to do. Can anyone point me to a tutorial which covers more than the Vigor's menu options. I've looked at those and they seems easy enough, but I want to understand the basic concepts behind this.

Which connection method should I use?... Do I NEED a static IP from my ISP? How do I create the accounts needed on the router side, and then what do I need to do from each of the following clients. Win XP, Win 7, Mac OSX

Any help appreciated.
