I have this exact setup, where the host operating system is Ubuntu.

So you're saying that when i run the web server, I need to explicitly  
state the mac address as stated above? If so, what about the XP  
machine. I've tried setting the mac address to something different,  
but so far it hasn't worked. Let me try this again.
