Example: Allowing Web or FTP Request using
NAT Static Mappings
Two of the most common reasons to use NAT static mappings are to run a web server or FTP server on a computer connected to the Diva 2440. Use the following diagram as a reference as you examine the NAT mapping examples that follow. Note that the Diva 2440 has been assigned the static IP address 223.132.212.39.
Diva 2440
Configuring for | FTP traffic is carried on TCP ports 20 and 21. Therefore, the following two |
FTP Traffic | NAT mappings would be required: |
Configuring for Web Web traffic is carried on TCP port 80. Therefore, the following NAT
Traffic | mapping would be required: |
To access the web server, a remote computer uses the URL HTTP://223.132.212.39/. The Diva 2440 sees that the datagram is intended for port 80 and forwards all web traffic to the appropriate computer on the internal LAN.
