This is my first attempt at editing and fixing someone else tutorial.
You will need a tunnel broker, and you can follow my guide and use Hurricane Electric. Once you have your account set up, you will need to create a regular tunnel, and all you have to do is enter in your public IP address which can be found at http://whatismyipaddress.com/.
With that set up, now you will need to get your tunnel info. Here is an example:
Server IPv4 Address: 184.108.40.206
Server IPv6 Address: 2001:480:a:40b::1/64
Client IPv4 Address: 123.456.789.101 (Your IP address here)
Client IPv6 Address: 2001:480:a:40b::2/64
