Prestige 1100 Internet Access Router

If you do not define any server, SUA offers the additional benefit of firewall protection. If no server is defined, all incoming inquiries will be filtered out by your Prestige and thus preventing intruders from probing your network.

Your Prestige accomplishes this address sharing by translating the internal LAN IP addresses to a single address that is globally unique on the Internet. For more information on IP address translation, refer to RFC 1631, The IP Network Address Translator (NAT).

3.6.1 Advantages of SUA

In summary:

SUA is a cost-effective solution for small offices with less than 20 hosts to access the Internet or other remote TCP/IP networks.

SUA supports servers to be accessible to the outside world.

SUA can provide firewall protection if you do not specify any server. All incoming inquiries will be filtered out by your Prestige 1100.

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

3.6.2 Single User Account Configuration

The steps for configuring your Prestige for Single User Account are identical to the conventional Internet access (See configuration instructions in Table 3-4) 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 -- WAN connections and not for connections between LANs.
