Configuring Wireless Interfaces
A Wireless interface is an interface that has been assigned to a Wireless zone and is used to
support SonicWALL SonicPoint secure access points.
Step 1 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.
Step 2 In the Zone list, select WLAN or a custom Wireless zone.
Step 3 Enter the IP address and subnet mask of the Zone in the IP Address and Subnet Mask fields.
Note 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.
Step 4 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.
