Setting Up ZENCART with WAMP for internet access

Hi
I have a home based LAN, a wireless router with number of PC's & laptops all connected to the Internet. I downloaded WAMP and zencart on to my laptop ok, configured my shop ok, but its only available locally on my Laptop.

I now want to make it available over the internet so that certain individual can test it, with strong security.

How can I make my Laptop into a fully accessible web server, as its got Apache, and if possible how do i make it so that those individual who I want to have access can only get access to my laptop webserver with a username and password?

Many Thanks

While not impossible this is not fully simple as you are not most likely on a dedicated IP and when it changes - no access...

You have to have a domain name and nameservers setup registered with a DNS server etc etc...

easiest to just obtain a hosting account and leave this to them

However, as Kobra has stated, this method
of hosting zencart site cannot be guaranteed
from security point of view. Testing would be fine.
