Network
Address
Translation
With Network Address Translation (NAT), you can
translate an Internet protocol address 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).
Press [SPACE BAR] and then [ENTER] to select either
Full Feature, None or SUA Only.
Choose None to disable NAT.
Choose SUA Only if you have a single public IP address.
SUA (Single User Account) is a subset of NAT that
supports two types of mapping: Many-to-One and Server.
Choose Full Feature if you have multiple public IP
addresses. Full Feature mapping types include:
One-to-One, Many-to-One (SUA/PAT), Many-to-Many
Overload, Many- One-to-One and Server. When you
select Full Feature you must configure at least one
address mapping set!
See Chapter 9, “Network Address Translation (NAT),” on
page 107 for a full discussion on this feature.
