I just replied your pm with a link that should allow you to dl the article.

As for how to port forwarding, Its a very very complicated task. Count yourself lucky if you can find the instructions on portforward.com, count yourself even luckier if it actually works.

Btw, if you use a router and port forwarding doesn't seem to work, biggest potential problem is that you need a static ip address which was very very bothersome to set up.....
