FIELD DESCRIPTION EXAMPLE
Network
Address
Translation Network Address Translation (NAT) allows the translation of 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 the Network Address Translation (NAT) chapter for a full discussion on
this feature.
