Novell BorderManager 3.9 Network Address Translation (NAT) allows IP clients on your local network to access the Internet without requiring you to assign globally unique IP addresses to each system.
In addition, NAT acts as a filter, allowing only certain outbound connections and guaranteeing that inbound connections cannot be initiated from the public network.
NAT configuration consists of selecting one of the following three modes:
Dynamic only: Dynamic-only mode is used to allow clients on your private network to access a public network, such as the Internet.
Static only: Static-only mode is used to allow clients on the public network to access selected resources on your private network, or to allow specified private hosts to access public hosts. Static-only mode requires the additional configuration of a network address translation table.
A combination of static and dynamic: The combination static and dynamic mode is used when functions of both the static mode and the dynamic mode are required. The combination static and dynamic mode also requires the configuration of a network address translation table for the static mode.

NOTE:This section describes the tasks required to set up an initial implementation of Novell BorderManager 3.9 NAT. For planning and conceptual information about NAT, refer the Novell BorderManager 3.9 Overview and Planning Guide , available in the online documentation.
Make sure you understand this information before setting up and configuring NAT.
