IP Address This option is available if you select Routing in the Mode field.
A static IP address is a fixed IP that your ISP gives you. A dynamic IP address is not fixed;
the ISP assigns you a different one each time you connect to the Internet. The Single User
Account feature can be used with either a dynamic or static IP address.
Click Obtain an IP Address Automatically if you have a dynamic IP address; otherwise
click Static IP Address and type your ISP assigned IP address in the IP Address text box
below.
Connection Select Connect on Demand when you don't want the connection up all the time and specify
an idle time-out (in seconds) in the Max. Idle Timeout field. The default setting selects
Connection on Demand with 0 as the idle time-out, which means the Internet session will
not timeout.
Select Nailed-Up Connection when you want your connection up all the time. The Prestige
will try to bring up the connection automatically if it is disconnected.
The schedule rule(s) in SMT menu 26 has priority over your Connection settings.
Network This option is available if you select Routing in the Mode field.
Address
Network Address Translation (NAT) allows the translation of an Internet protocol address
Translation
used within one network (for example a private IP address used in a local network) to a
different IP address known within another network (for example a public IP address used on
the Internet).
Choose SUA Only if you have a single public IP address. SUA (Single User Account) is a
subset of NAT that maps one public IP address to many private IP addresses.
Choose Full Feature if you have multiple public IP addresses. When you select Full Feature,
you must use the NAT address mapping rules screen to configure at least one address
mapping set. Full Feature mapping types include: One-to-One, Many-to-One (SUA), Many-
to-Many Overload, Many-to-Many No Overload and Server.
Choose None to disable NAT. Refer to the NAT chapter for more details.
