Web Server
At this point you have a computer that has an active DSL connection to the Internet with a static IP address.
Your computer should be connected to a router that has "Port Forwarding" configured to point to LAN IP 192.168.1.3

Your computer should have a static LAN IP 192.168.1.1 address

You have successfully install Apache web server software.

You have successfully accessed you web site (Apache default page) via both your LAN IP and your Wan IP.

You purchased a Domain Name.

You have appointed a DNS service to handle the DNS for your domain name.

You have changed the Name Server information with your registrar, DirectNIC, to point to the Name Servers at which your DNS provider has given you. (Nameserver 1: ns1.example.com, Nameserver 2: ns2.example.com)

If all of the above information has been configured properly, your domain name will be mapped to your web server within 24-72 hours.

You now have a web server running "your-domain.com" on your computer. Remember, if you turn off your computer, people will not be able to access you web site.
