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.

as they have to pay for a single globally unique IP address only.

4.1.2 Single User Account Configuration

The steps for configuring your Prestige for Single User Account is identical to conventional Internet access
(see configuration instructions in the previous chapter) 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 to WAN connections and not for connections between LANs.
