Configuring NAT Policies
NAT policies allow you 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.
The following NAT configurations are available in SonicOS
Enhanced:
• Many-to-One NAT Policy
• Many-to-Many NAT Policy
• One-to-One NAT Policy for Outbound Traffic
• One-to-One NAT Policy for Inbound Traffic (Reflexive)
• One-to-Many NAT Load Balancing
• Inbound Port Address Translation via One-to-One NAT
Policy
• Inbound Port Address Translation via WAN IP Address
This section describes how to configure a One-to-One NAT
policy. One-to-One is the most common NAT policy used to
route traffic to an internal server, such as a Web Server. Most of
the time, this means that incoming requests from external IPs
are translated from the IP address of the SonicWALL security
appliance WAN port to the IP address of the internal web
server.
