Multiple websites on IIS4

I have a NT4 webserver that has an Intranet site on it, that site is working fine inoffice and out. I added another domain name to the machine and assigned a second IP to the NIC. In IIS I have the new www.myserver.com assigned the new IP and can ping and view the website in-house. When I go to a machine in the outside world, I cannot open the page. The Domain is registered properly as DNS is able to resolve the IP to the domain, it just doesn’t return the page. This Server is NT4 SP6A IIS4Proxy 2.0 SP2.

I thought at one time there were Technet docs on how this is done. I cannot find much on IIS 4 on my CD’s since MS released IIS5.
