Web problem

Hi,

Can someone show me how to redirect http request for our web page to go externally? For example, our domain name is example.com and our website is also example.com. I have created a DNS host file to point it to your web site, which is hosted externally. Everything is working fine but the only problem I’m having is that when internal people type in example.com (without the www) it takes them to our internal web site that does not exist since we only use it for Outlook Web Access. I want to be able to configure it so when internal user type in example.com or www.example.com it will take them to our website.

Thanks!
