VMWare Server 1.0.4 - Windows XP Networking

I installed VMWare Server 1.0.4 on my dedicated server, and set-up a new Windows XP Professional VM.

I have 3 more IP's that are not used.

When installing the VM, I used NAT networking to share my main OS network with my private VPS, but basically no one can access the VM from the outside world. I can surf the net while being on NAT status in the VM, but if I try to run any service like Apache, no one can enter to the service besides the localhost.

My VPS is running Windows XP Professional SP2 with a legal retail license and my main OS on the server is CentOS 4.5 (detailed hardware is mentioned below)

Do you have any idea how can I configure my network so anyone can enter the VPS?

And please, if you can explain me step by step because I'm a real newbie hehe

Kind Regards,
