information on configuring global signature groups, refer to “Configuring Global Signature 
Groups” in the SonicWALL Intrusion Prevention Service Administrator’s Guide available on the 
SonicWALL Resource CD or at 

Leaving the High Priority Attacks, Medium Priority Attacks, and Low Priority Attacks 
signature groups with no Prevent All action checked means no intrusion prevention is 
occurring on the SonicWALL security appliance. 

You apply SonicWALL IPS 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.

In the IPS Status section of the Security Services > Intrusion Prevention Service page, click 
the Network > Zones link to access the Network > Zones page. You apply SonicWALL IPS to 
a zone listed on the Network > Zones page.

To enable SonicWALL on a zone, perform these steps:

In the SonicWALL security appliance management interface, select Network > Zones or from 
the IPS Status section, on the Security Services > Intrusion Prevention page, click the 
Network > Zones link. The Network > Zones page is displayed.

In the Configure column in the Zone Settings table, click the edit icon 

 for the zone you 

want to apply SonicWALL IPS. The Edit Zone window is displayed.

Click the Enable IPS checkbox. A checkmark appears. To disable SonicWALL IPS, uncheck 
the box.

Click OK.

You also enable SonicWALL IPS protection for new zones you create on the Network > Zones 
page. Clicking the Add button displays the Add Zone window, which includes the same 
settings as the Edit Zone window.
