Prestige 2602RL-D3A Support Notes
The NAT Server Set is a list of LAN side servers mapped to external ports (similar to the old SUA menu of before). If you wish, you can make inside servers for different services, e.g., Web or FTP, visible to the outside users, even though NAT makes your network appears as a single machine to the outside world. A server is identified by the port number, e.g., Web service is on port 80 and FTP on port 21.
As an example (see the following figure), if you have a Web server at 192.168.1.36 and a FTP server at 192.168.1.33, then you need to specify for port 80 (Web) the server at IP address 192.168.1.36 and for port 21 (FTP) another at IP address 192.168.1.33.
Please note that a server can support more than one service, e.g., a server can provide both FTP and Mail service, while another provides only Web service.
The following procedures show how to configure a server behind NAT.
Step 1. Enter 15 in the Main Menu to go to Menu
Step 2. Enter 2 to go to Menu 15.2.1-NAT Server Setup.
Step 3. Enter the service port number in the Port# field and the inside IP address of the server in the IP Address field.
Step 4. Press [SPACEBAR] at the 'Press ENTER to confirm...' prompt to save your configuration after you define all the servers or press ESC at any time to cancel.
