3.4Single User Account (SUA)

Typically, if there are multiple users on the LAN wanting to concurrently access the Internet, you have to lease a block of legal, or globally unique, IP addresses from the ISP.

The Single User Account (SUA) feature allows you to have the same benefits as having multiple legal addresses, but only pay for one IP address, thus saving significantly on the subscription fees. (Check with your ISP before you enable this feature). SUA supports popular Internet applications such as MS traceroute, CuSeeMe, IRC, RealAudio, VDOLive, Quake and PPTP with no extra configuration needed.

The IP address for the SUA can be either fixed or dynamically assigned by the ISP. In addition, you can designate servers, e.g., a web server and a telnet server, on your local network and make them accessible to the outside world. If you do not define any server, SUA offers the additional benefit of firewall protection. If no server is defined, all incoming inquiries are filtered out by your Prestige, 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).

3.4.1 Advantages of SUA

SUA is an ideal, cost-effective solution for small offices 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 a server. All incoming inquiries are filtered out by your Prestige.

UDP and TCP packets can be routed. In addition, partial ICMP, including echo and traceroute, is also supported.
