For more information on IP address translation as a solution for IP address depletion problem, refer to RFC
1631, The IP Network Address Translator (NAT).
In summary:

•

 

SUA helps in more efficient IP address management.

•

 

SUA can provide firewall protection.  All incoming inquiries will be filtered out by your Prestige.

•

 

UDP and TCP datagrams can be routed.  In addition, partial ICMP, including echo (ping) and trace
route, is supported.

•

 

SUA is also a cost-effective solution for offices to access the Internet or other remote TCP/IP networks
as they have to pay for single globally unique IP address only.

The steps for configuring your Prestige for Single User Account are identical to conventional Internet access
(See configuration instructions in the previous chapter) with the exception that you need to fill in two extra
fields in Menu 4 - Internet Access Setup, as shown in the following figure. SUA here is applied solely to
the output interface and is valid only for LAN to WAN connections and not for connections between LANs.

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).
Follow the instructions on how to configure the SUA fields in the following table.
