3.4.2 Single User Account Configuration
The steps for configuring your Prestige for Single User Account are identical to the conventional Internet
access with the exception that you need to fill in two extra fields in Menu 4 – Internet Access Setup (please
refer to Figure 3-3). To enable the SUA feature in Menu 4, move the cursor to the Single User Account field
and select Yes (or No to disable SUA). Then follow the instructions on how to configure the SUA fields.

IP Address
If your ISP did not assign you a static IP address, enter [0.0.0.0]
here; otherwise, enter that IP address here.
Press the [Enter] key at the message [Press ENTER to Confirm . . . ] to save your
configuration, or press the [Esc] key at any time to cancel.
3.5 Multiple Servers Behind the SUA
If you wish, you can make inside servers for different services, e.g., web or FTP, visible to the outside users,
even though SUA makes your whole internal network appear as a single machine to the outside world. A
service 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 an 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 DNS
service, while another provides only web service. Also, since you need to specify the IP address of a server in
the Prestige, a server must have a fixed IP address and not be a DHCP client whose IP address potentially
changes each time it is powered on.
In addition to the servers for specific services, SUA supports a default server. A service request that does not
have a server explicitly designated for it is forwarded to the default server. If the default server is not defined,
the service request is simply discarded.
