DESCRIPTION:

NOTE: The proxy server must be located on the WAN or DMZ; it can not be located on the LAN.

Scenario 1: Proxy Web server is located on DMZ zone

1. Login to the SonicWall management interface and navigate to Manage | Network | Web Proxy.
2. Enter the Web Proxy server Name or IP address: e.g. 192.168.2.250.
3. Enter the Proxy server Port: e.g. 8080 (assuming proxy server is configured to listen on port 8080).
4. Click Apply to save the changes
   

SonicOS will auto add two NAT policies:

1. The first will translate the traffic from Web Proxy Server back to HTTP.
2. The second will forward HTTP request coming from all LAN PC's to the Web Proxy Server (192.168.2.250) on Port 8080, which is reachable via DMZ interface.

NOTE: These are auto generated NAT policies and cannot be edited/modified.

Scenario 2: Proxy Web Server located on WAN zone

1. Login to the SonicWall management interface and navigate to Manage | Network | Web Proxy.
2. Enter the Proxy server Name or IP address: e.g. 1.1.1.5.
   
3. Enter the Proxy server Port: e.g. 8080 (assuming proxy server is configured to listen on port 8080).
4. Click Apply to save the changes.
   

 SonicOS will auto add one NAT policy:

1. The policy will forward HTTP requests coming from all LAN PC's to the Web Proxy Server (1.1.1.5) on Port 8080, which is reachable via the WAN / X1 interface.

NOTE: This is an auto generated NAT policy and cannot be edited/modified.
