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 a single globally unique IP address only.
