You apply SonicWall IPS protection to zones on the Network > Zones page to enforce SonicWall IPS not only between each network zone and the WAN, but also between internal zones. For example, enabling SonicWall IPS on the LAN zone enforces SonicWall IPS on all incoming and outgoing LAN traffic.
To enable SonicWall IPS protection on a zone, follow the procedure for applying SonicWall GAV protection described in Applying SonicWall GAV Protection on Zones, only in Step 3, click the Enable IPS check box.
NOTE: You also enable SonicWall IPS protection for new zones you create on the Network > Zones page. Clicking the Add button displays the Add Zone dialog, which includes the same settings as the Edit Zone dialog.
