    • You should see your server's webpage

Step 6 - Setup the DNS Nameserver

This step will simulate the purchase of a domain name for your home server from an Internet Registrar such as GoDaddy. This will allow users from the web to access your server by name.

  1. Click The Config tab on the DNS server
  2. Click DNS under services
  3. Next to Name enter www.myhomewebsite.com
    ex: www.bob.com

  7. Test these ettings
    • Click on the Internet Webserver
    • Open the browser an enter the name you put into DNS (www.myhomewebsite.com)
    • You should see your website

Note: If you try to access your server by this name from inside the home network you will NOT be successful. This is because the pc's on your network know your server's address as, not as the address on the Internet port of your router.
