SonicOS will auto add two NAT policies:

The first will translate the traffic from Web Proxy Server back to HTTP.
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.
