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.
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 subinterfaces 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.
|
Note The above table depicts the maximum subnet mask sizes allowed. You can still use class-full subnetting (class A, class B, or class C) or any variable length subnet mask that you wish on WLAN interfaces. You are encouraged to use a smaller subnet mask (e.g. 24-bit class C - 255.255.255.0 - 254 total usable IPs), thus allocating more IP addressing space to clients if you have the need to support larger numbers of wireless clients.
Step 5 Enter any optional comment text in the Comment field. This text is displayed in the Comment column of the Interface table.
Step 6 If you want to enable remote management of the SonicWALL security appliance from this interface, select the supported management protocol(s): HTTP, HTTPS, SSH, Ping, SNMP, and/or SSH.

• Static - configures the SonicWALL for a network that uses static IP addresses.
• DHCP - configures the SonicWALL to request IP settings from a DHCP server on the Internet. NAT with DHCP Client is a typical network addressing mode for cable and DSL customers.
• PPPoE - uses Point to Point Protocol over Ethernet (PPPoE) to connect to the Internet. If desktop software and a username and password is required by your ISP, select NAT with PPPoE. This protocol is typically found when using a DSL modem.
• PPTP - uses PPTP (Point to Point Tunneling Protocol) to connect to a remote server. It supports older Microsoft Windows implementations requiring tunneling connectivity.
• L2TP - uses IPsec to connect a L2TP (Layer 2 Tunneling Protocol) server and encrypts all data transmitted from the client to the server. However, it does not encrypt network traffic to other destinations.
Note For Windows clients, L2TP is supported by Windows 2000 and Windows XP. If you are running other versions of Windows, you must use PPTP as your tunneling protocol.
Step 4 If you want to enable remote management of the SonicWALL security appliance from this interface, select the supported management protocol(s): HTTP, HTTPS, SSH, Ping, SNMP, and/or SSH. You can also select HTTP for management traffic. However, bear in mind that HTTP traffic is less secure than HTTPS.

You can choose to override the Default MAC Address for the Interface by selecting Override Default MAC Address and entering the MAC address in the field.
Caution If you select a specific Ethernet speed and duplex, you must force the connection speed and duplex from the Ethernet card to the SonicWALL as well.
Check Enable Multicast Support to allow multicast reception on this interface.
On SonicWALL NSA series appliances, check Enable 802.1p tagging to tag information passing through this interface with 802.1p priority information for Quality of Service (QoS) management. Packets sent through this interface are tagged with VLAN id=0 and carry 802.1p priority information. In order to make use of this priority information, devices connected to this interface should support priority frames. QoS management is controlled by access rules on the Firewall > Access Rules page. For information on QoS and bandwidth management, see Firewall Settings > QoS Mapping.
You can also specify any of these additional Ethernet Settings:
• Interface MTU - Specifies the largest packet size that the interface can forward without fragmenting the packet.
• Fragment non-VPN outbound packets larger than this Interface’s MTU - Specifies all non-VPN outbound packets larger than this Interface’s MTU be fragmented. Specifying the fragmenting of VPN outbound packets is set in the VPN > Advanced page.
• Ignore Don’t Fragment (DF) Bit - Overrides DF bits in packets.
• Do not send ICMP Fragmentation Needed for outbound packets over the Interface MTU - blocks notification that this interface can receive fragmented packets.
Bandwidth Management
SonicOS Enhanced can apply bandwidth management to both egress (outbound) and ingress (inbound) traffic on the interfaces in the WAN zone. Outbound bandwidth management is done using Class Based Queuing. Inbound Bandwidth Management is done by implementing ACK delay algorithm that uses TCP’s intrinsic behavior to control the traffic.
Class Based Queuing (CBQ) provides guaranteed and maximum bandwidth Quality of Service (QoS) for the SonicWALL security appliance. Every packet destined to the WAN interface is queued in the corresponding priority queue. The scheduler then dequeues the packets and transmits it on the link depending on the guaranteed bandwidth for the flow and the available link bandwidth.
Use the Bandwidth Management section of the Edit Interface screen to enable or disable the ingress and egress bandwidth management. Egress and Ingress available link bandwidth can be used to configure the upstream and downstream connection speeds in kilobits per second.
Note The Bandwidth Management settings are applied to all interfaces in the WAN zone, not just to the interface being configured.
• Enable Egress Bandwidth Management - Enables outbound bandwidth management.
– Available Interface Egress Bandwidth (Kbps) - Specifies the available bandwidth for WAN interfaces in Kbps.
• Enable Ingress Bandwidth Management - Enables inbound bandwidth management.
• Available Interface Ingress Bandwidth (Kbps) - Specifies the available bandwidth for WAN interfaces in Kbps

• Configuring the ADSL Expansion Module
• Configuring the T1/E1 Module
• Configuring the LAN Bypass Module
• Configuring the 2 Port SFP or 4 Port Gigabit Ethernet Modules
Configuring the ADSL Expansion Module
ADSL is an acronym for Asymmetric Digital Subscriber Line (or Loop). The line is asymmetric because, when connected to the ISP, the upstream and downstream speeds of transmission are different. The DSL technology allows non-voice services (data) to be provided on regular single copper wire-pair POTS connections (such as your home phone line). It allows voice calls and data to pass through simultaneously by using higher band frequencies for data transmission.
The SonicWALL ADSL module cards support only one subscriber ADSL line (one port). Two types of ADSL module cards are supported:
• 1 Port ADSL (RJ-11) Annex A – ADSL over plain old telephone service (POTS) with a downstream rate of 12.0 Mbit/s and an upstream rate of 1.3 Mbit/s.
• 1 Port ADSL (RJ-45) Annex B – ADSL over an Integrated Services Digital Network (ISDN) with a downstream rate of 12.0 Mbit/s and an ups.tream rate of 1.8 Mbit/s.
The following ADSL standards are supported
|
The ADSL module card uses 2 LEDs to indicate connectivity status. The upper green LED is the ADSL link. Its status is as follows:
• OFF - No link
• ON - ADSL link is active
The lower green LED shows the system and ADSL module activity.
• If it is OFF, there is no activity.
• If it displays a slow blink rate, it signifies activity on system management interface.
• If it displays a fast blink rate, there is data activity on ADSL line.
The ADSL module card is detected on boot, and assigned an interface name of M0 or M1. The interface name is based to it based on the expansion slot hosting the module card. You will see the assigned entry when you log into the Network Interfaces page.
The ADSL interface never unassigned. When plugged in, it is always present in the WAN zone and zone assignment cannot be modified by the administrator
Click on the Configure 
icon to the right of the interface entry. You will see a menu with three tabs: General, Advanced, and DSL Settings. The DSL Settings tab allows you to configure ISP-specific settings for the ADSL connection.
It displays the configurable DSL fields:
Virtual Path Identifier (VPI)
Virtual Channel Identifier (VCI)
Multiplexing Method (LLC or VC)
The values for these parameters should match the settings on the ISP DSLAM, and are provided by the ISP. These values vary from one ISP to another, and from country to country.
The SNWL default uses the most common values in the USA. The VPI and VCI settings are used to create the Permanent Virtual Circuit (PVC) from the NSA2400MX to the ISP DSLAM.
When finished configuring these ISP settings, click OK.
The Ethernet-specific settings on the Advanced tab, even if set, do not apply to the ADSL module. The Link Speed field in the Advanced tab has a fixed "N/A" selection, since it does not apply to ADSL. The ADSL link speed can't be customized but is predetermined by the DSL Provider.
The standard WAN ethernet settings are not affected by the presence of the ADSL module.
When the ADSL module is first plugged in, it should be added to the WAN Load Balancing default group so that the ADSL module can be used to handle default route traffic. Go to the Failover and LB screen and click the Configure 
icon to edit the settings.
On the General menu, add the ADSL interface to the Load Balancing group. If the default primary WAN, X1, is unused or unconfigured, it can be removed for a cleaner interface configuration.
When done, click OK, and the ADSL module will be added to the group.
The 1-port T1/E1 Module provides the connection of a T1 or E1 (digitally multiplexed telecommunications carrier system) circuit to a SonicWALL appliance using an RJ-45 jack.
The SonicWALL T1/E1 module fully supports Point-to-Point Protocol (PPP) and Cisco HDLC encapsulation, and can connect to Cisco routers and HP ProCurve devices.
Note Only one T1/E1 module can be configured on each appliance.
To configure the T1/E1 Module, perform the following tasks:

• When E1 is selected the choices are: FAS, MFAS
Step 8 Select the DSO speed: 56 KB or 64KB (default).
If desired, you can specify the Data DSO range.
For T1, the range is 1 to 24 (default)
For E1, the range is 1 to 31
Each number can be individually set. For example, “5 to 15”, “1 to 1”, 1 to 20” are valid settings.
Step 9 Line Build Out is available with T1. The options are: 0.0 dB, -7.5 dB, -15 dB, -22.5 dB.
CRC is configured with an enable/disable check-box. When T1 is selected, the check-box is labeled CRC6, when E1 is selected the check-box is labeled CRC4.
You can also choose to enable multicast.
Step 10 When finished with configuration, click OK.
The T1/E1 module interface will be added to the pool of available WAN interfaces
Configuring the LAN Bypass Module
This module allows you to perform a physical bypass of the firewall when the interface is bridged to another interface with LAN bypass capability. This allows network traffic to continue flowing if an unrecoverable firewall error occurs.
Step 1 Click on the Edit 
icon in the Configure column for the Interface of the expansion module you want to configure. The Edit Interface window is displayed. The Bypass option is only displayed if an interface capable of performing the bridge is present.
Step 2 The window shows the LAN interface, and has a checkbox “Engage Physical ByPass on Malfunction” to enable the physical bypass feature. This is only displayed when the interface is bridged to another interface capable of performing the LAN bypass. Enabling this checkbox means that the packets between the bridged pairs will not fail, even if the firmware or NSA appliance fails.
If the checkbox is not enabled, the ports will behave like normal Ethernet ports.
