On the Network > NAT Policies page, notice a radio button labeled System Polices. If you choose this radio button, the NAT Polices page displays all of the default, auto-created NAT policies for the SonicWall security appliance. These policies are default settings for the SonicWallSonicWall security appliance to operate properly, and cannot be deleted. For this reason, they are listed in their own section, in order to make the user-created NAT policies easier to browse. If you wish to see user-created NAT policies along with the default NAT policies, simply check the radio button next to ‘All Policies’.
