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.

For other NAT configurations, see the SonicOS Enhanced

Administrator’s Guide.

An example configuration illustrates the use of the fields in the

Add NAT Policy procedure. To add a One-to-One NAT policy

that allows all Internet traffic to be routed through a public IP

address, two policies are needed: one for the outbound traffic,

and one for the inbound traffic. To add both parts of a One-to-

One NAT policy, perform the following steps:

1. Navigate to the Network > NAT Policies page. Click Add.

The Add NAT Policy dialog box displays.

2. For Original Source, select Any.

3. For Translated Source, select Original.

4. For Original Destination, select X0 IP.

5. For Translated Destination, select Create new address

object and create a new address object using WAN for

Zone Assignment and Host for Type.

6. For Original Service, select HTTP.

7. For Translated Service, select Original.

8. For Inbound Interface, select X0.

9. For Outbound Interface, select Any.

10. For Comment, enter a short description.

11. Select the Enable NAT Policy checkbox.

12. Select the Create a reflexive policy checkbox if you want

a matching NAT Policy to be automatically created in the

opposite direction. This will create the outbound as well as

the inbound policies.
