I also would like to thank you for the tutorial all the help you give.
I am receiving the URL not reachable error as well, I have pinged my domain with and without the www, and I get 2 different IP's in the results. Without www, I see the local IP of the server, not the outside IP. With www, I see a wierd IP address, and nothing finishes transmitting.
If I put www.mydomain.com
in my browser, it does go to the index of my server. I don't know if that means anything however. Any help is appeciated. Thanks,
