Prestige 310 Broadband Sharing Gateway
4-2 SUA and Multiple SUA Servers
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.
