Remote Viewing

Ok so the problem is no one but me can view this site.
I am using XAMPP 1.6.8 which has Apache and My SQL. (I am not to saving editing conf. files :D) What I should be able to do is type in my current IP:80 and get to my WordPress index page. It doesn’t happen i go to XAMPP page. I understand this is kinda not the right website but it does deal with this wonderful program that I SOOOOO want to work. Any help would be greatly appreciated.
