Configure IIS 7.0 for all my laptops in my home network

Hi all of you,

Primary platform: Framework 4.0, VS 2010. Web project HTML5, C# language.

My goal is be to able to see my website from any laptop at home.

I've configured my IIS 7.0 for my website without problems but when I try to load my website from other laptop connected to the same ISP router it does not work, i.e, my MacBook

How can I do in order to sort out this issue?

I've already opened my Windows Firewall in the machine where I am developing my project. Ports 80 both TCP and UDP protocols.

What else would need I?

Thanks for any input or hint provided,
