Thank you for your help!! Cox provides the public / routable IP which is set on my router / modem. I have a web server that servers several websites. I use NAT for port forwarding to that one box. Without a DNS server, either local or external, how will Apache know which site to server up? If I put the IP in my browser I get the default "website" which is no website at all - it is the default welcome page.
