Hello, my first post to this site and apologize if this is in wrong area.

I have a site up and running with XAMPP on a WinXP pro machine without issues. What I am trying to do is get my second site I am working on running from same computer and access both sites through the internet. I been playing with Vhost but that seems to be for accessing from within my internal network.

I cant seem to grasp how to make sure when I'm out in the world and type ie. web2.com that my computer knows to give me my second website instead of my first site.
