SonicWALL TZ 190 Manuale Utente

A Wireless interface is an interface that has been assigned to a Wireless zone and is used to 
support SonicWALL SonicPoint secure access points. 

Click on the Configure icon 

 in the Configure column for the Interface you want to 

configure. The Edit Interface window is displayed. You can configure X2 through X9, Opt, a 
VLAN sub-interface or a PortShield interface. 

In the Zone list, select WLAN or a custom Wireless zone. 

Enter the IP address and subnet mask of the Zone in the IP Address and Subnet Mask fields.

The upper limit of the subnet mask is determined by the number of SonicPoints you select 
in the SonicPoint Limit field. If you are configuring several interfaces or sub-interfaces as 
Wireless interfaces, you may want to use a smaller subnet (higher) to limit the number of 
potential DHCP leases available on the interface. Otherwise, if you use a class C subnet 
(subnet mask of 255.255.255.0) for each Wireless interface you may exceed the limit of 
DHCP leases available on the security appliance.

In the SonicPoint Limit field, select the maximum number of SonicPoints allowed on this 
interface. 

This value determines the highest subnet mask you can enter in the Subnet Mask field. 
The following table shows the subnet mask limit for each SonicPoint Limit selection and 
the number of DHCP leases available on the interface if you enter the maximum allowed 
subnet mask.

Available Client IPs assumes 1 IP for the SonicWALL gateway interface, in addition to the 
presence of the maximum number of SonicPoints allowed on this interface, each 
consuming an IP address.
