NAT policies allow the flexibility to control Network Address
Translation based on matching combinations of Source IP
address, Destination IP address, and Destination Services.
Policy-based NAT allows you to deploy different types of NAT
simultaneously.
For configuration procedures and information regarding the
different types of NAT policies, such as Many-to-One, One-to-
One, or One-to-Many Load Balancing, refer to the SonicOS
Administrator's Guide.
