First You will need a program called Hamachi ™ To save you time of having to search for a link: https://secure.logmein.com/products/hamachi/list.asp
Now once you have gotten that done Start up hamachi
Then you need to Go to the little triangle then press Create a new network then name it whatever you want and put any password
Next find what your hamachi ip is it is at the very top of your hamachi window Write that down
Next open what the picture shows in red
