Description

A wireless interface is assigned to a WLAN zone and is used to support SonicWall Sonicpoint secure access. This article depicts how to configure the wireless interface in a static IP mode.

Resolution

Navigate to Network | Interfaces page and click on the Configure icon in the Configure column for the interface. The Edit Interface dialog box is displayed as following.

Example:

NSA3600 - v6.2.0.0
Interface - X7
IP address - 1.1.1.1
Subnet Mask - 255.255.255.0
SonicPoint - Limit 8 SonicPoints
A SonicPoint has been connected to interface X7.

Configuring General Settings for a Wireless Interface.

Step 1 In the Zone list, select WLAN or a custom Wireless zone.
Step 2 In the Mode/IP Assignment list, select Static IP Mode.

You can also select Layer 2 Bridged Mode (IP Route Option) or PortShield Switch Mode, of which the settings can be found in other KB articles.

Step 3 Enter the IP address and subnet mask of the zone in the IP address and Subnet Mask fields.

Step 4 In the SonicPoint Limit field, select the maximum number of SonicPoints allowed on the interface.

Note: If you want to use a smaller(higher subnet notation) subnet to limit the number of potential DHCP leases available on the interface, the maximum subnet mask is determined by the number of SonicPoints you select in this field.

SonicPoints per Interface	Maximum Subnet Mask	Total Usable IP addresses	Available Client IPs
No SonicPoints	30 bits-255.255.255.252	2	2
2 SonicPoints	29 bits-255.255.255.248	6	3
4 SonicPoints	29 bits-255.255.255.248	6	1
8 SonicPoints	28 bits-255.255.255.240	14	5
16 SonicPoints	27 bits-255.255.255.224	30	13
32 SonicPoints	26 bits-255.255.255.192	62	29
48 SonicPoints	25 bits-255.255.255.128	126	77
64 SonicPoints	25 bits-255.255.255.128	126	61
96 SonicPoints	24 bits-255.255.255.0	254	157
128 SonicPoints	23 bits-255.255.255.0	510	381

The firewall interface and the SonicPoints allowed on the interface, each will consume an IP address from the DHCP pool.

Step 5 Enter any optional comment text in the Comment field
Step 6 If you want to enable remote management of the firewall from this interface, select the supported management protocol(s): HTTPS, Ping, SNMP, and/or SSH from the Management field.
Step 7 If you want to allow selected users with limited management rights to log in to the security appliance, select HTTP and/or HTTPS in User Login field.
Step 8 Choose Automatically or Manually assign an IP address for the connected SonicPoint(s) in Reserve SonicPoint Address field.

Configuring Advanced Settings for a Wireless Interface.

In the Edit Interface dialog box, click the Advanced tab. The Advance page will be displayed as following. The configuration in this example can keep as default.

Step 9 Click OK button.

How to Check:

Reserve SonicPoint Address: Automatically.

Navigate to Network | DHCP Server. The DHCP range for wireless interface X7 has been dynamically added. For 1.1.1.0/24 network, IP address 1.1.1.1 has been configured as IP for firewall interface X7 and IP addresses1.1.1.247 to 1.1.1.254 have been automatically reserved for 8 SonicPoints.
Navigate to SonicPoint | SonicPoints. The SonicPoint connected to interface X7 has got the reserved IP address 1.1.1.247.

Reserve SonicPoint Address: Automatically.

Navigate to Network | DHCP Server. The DHCP range for wireless interface X7 has been dynamically added. For 1.1.1.0/24 network, IP address 1.1.1.1 has been configured as IP for firewall interface X7 and IP addresses1.1.1.2 to 1.1.1.9 have been automatically reserved for 8 SonicPoints.
Navigate to SonicPoin | SonicPoints. The SonicPoint connected to interface X7 has got the reserved IP address 1.1.1.2.
