Configuring for Internet Access 45

1. SUA is an ideal, cost-effective solution for small offices with

less than 20 hosts using a LAN to concurrently access the

Internet or other remote TCP/IP network.

2. SUA can provide one server address to be accessed by Remote

Dial-in Users, thus controlling the incoming packets.

3. SUA can provide firewall protection if you do not configure a

server IP address. All incoming inquiries will be filtered out by

the Prestige. Therefore, servers on your network are protected.

4. UDP and TCP datagrams can be routed. In addition, ICMP

echo can also be routed.

The figure below shows an example of a small office connected to

the Internet via a Single User Account using the Prestige. Note that

if you enable the Single User Account feature, your local IP

address MUST be selected from the list of IP addresses for private

networks as defined by the IANA.
