Add SSID Interfaces for Single Firewalls
You can define several SSID Interfaces for the Wireless Interface.
An SSID (service set identifier) interface represents an 802.11 wireless LAN. You can define several SSID Interfaces for the Wireless Interface.
For more details about the product and how to configure features, click Help or press F1.
Steps
SSID Interface Properties dialog box
Use this dialog box to configure properties for SSID interfaces.
Option | Definition |
---|---|
General tab | |
Wireless Network Name (SSID) | The name that identifies the network to the end users. |
Wireless SSID Broadcast | Select one of these options:
Note: Even if you disable SSID broadcast, anyone within range can discover your wireless network with detection tools widely available on the Internet.
|
MAC Address Type | Select one of these options:
|
MAC Address
(Custom only) |
Enter the custom MAC address. |
Zone
(Optional) |
Select the network zone to which the interface belongs. Click Select to select an element, or click New to create an element. |
Comment (Optional) |
A comment for your own reference. |

General tab, Quality of Service and Bandwidth Management section | |
QoS Mode
(Optional) |
Defines how QoS is applied to the link on this interface. If Full QoS or DSCP Handling and Throttling is selected, a QoS policy must also be selected. If Full QoS is selected, the throughput must also be defined. If the interface is a Physical Interface, the same QoS mode is automatically applied to any VLANs created under it. |
QoS Policy
(DSCP Handling and Throttling and Full QoS modes only) |
The QoS policy for the link on this interface. If the interface is a Physical Interface, the same QoS policy is automatically selected for any VLANs created under it. Note: If a Virtual Resource has a throughput limit defined, the interfaces on the Virtual NGFW Engine that use a QoS policy all use the same policy. The policy used in the first interface is used for all the interfaces.
|
Interface Throughput Limit
(Full QoS mode only) |
Enter the throughput for the link on this interface as megabits per second. If the interface is a Physical Interface, the same throughput is automatically applied to any VLANs created under it. The throughput is for uplink speed (outgoing traffic) and typically must correspond to the speed of an Internet link (such as an ADSL line), or the combined speeds of several such links when connected to a single interface. CAUTION: Make sure that you set the interface speed correctly. When
the bandwidth is set, the NGFW Engine always scales the total amount of traffic on this interface to the bandwidth you defined. This
scaling happens even if there are no bandwidth limits or guarantees defined for any traffic.
CAUTION: The throughput for a Physical Interface for a Virtual NGFW Engine must not be higher than the throughput for the Master NGFW Engine interface that hosts
the Virtual NGFW Engine. Contact the administrator of the Master NGFW Engine before changing
this setting.

Key Length
(WEP Open System, WEP Shared Key only) |
Select the encryption key length for WEP. |
Default Key
(WEP Open System, WEP Shared Key only) |
Select the encryption key to use by default for WEP. |
Key
(WEP Open System, WEP Shared Key only) |
Enter 1–4 decryption keys for WEP. |
WPA Mode
(WPA Personal, WPA Enterprise only) |
Select the encryption mode to use for WPA. |
Pre-Shared Key
(WPA Personal only) |
Enter the pre-shared key for WPA Personal. |
Authentication Method
(WPA Enterprise only) |
Click Select to select the authentication method for WPA Enterprise. |
Hide
(WEP Open System, WEP Shared Key, WPA Personal only) |
Prevents the password or key from being shown as plain text. Deselect this option to show the password. Selected by default. |

DHCP tab, DHCP Relay settings (If DHCP Mode is DHCP Relay) |
|
Resources | Select from the available DHCP servers. |
Search | Opens a search field for the selected element list. |
Up | Navigates up one level in the navigation hierarchy. Not available at the top level of the navigation hierarchy. |
Tools |
|
Add | Adds the DHCP server to the interface. |
Remove | Removes the DHCP server from the interface. |
Max Packet Size | Adjusts the maximum allowed packet size. |
DHCP Relay | Select the CVI or IP address you want to use for DHCP relay. |
Option | Definition |
---|---|
DHCP tab, DHCP Server settings (If DHCP Mode is DHCP Server) |
|
DHCP Address range | Defines the DHCP address range that the Firewall assigns to clients in one of the following ways:
Note: The DHCP address range must be in the same network space defined for the Physical Interface. The DHCP address range must not contain the Firewall's NDI or CVI addresses or broadcast IP addresses of networks behind the Firewall.
|
Primary DNS Server | Enter the primary DNS server IP address that clients use to resolve domain names. If there is a listening IP address for DNS Relay on the same interface, clients use the DNS services provided by the firewall by default. If you want clients to use a different external DNS server, enter the IP address of the external DNS server. |
Secondary DNS Server | Enter the secondary DNS server IP address that clients use to resolve domain names. |
Primary WINS Server | Enter the primary WINS server IP address that clients use to resolve NetBIOS computer names. |
Secondary WINS Server | Enter the secondary WINS server IP address that clients use to resolve NetBIOS computer names. |
Default Gateway | Enter the IP address through which traffic from clients is routed. |
Default Lease Time | Enter the time after which IP addresses assigned to clients must be renewed. |
Domain Name Search List
(Optional) |
Enter a comma-separated Domain Name Search List to configure DNS search suffixes. |

Override Engine's Default Settings | When selected, the default settings of the engine are overridden. |
SYN Rate Limits |
|
Allowed SYNs per Second | Defines the number of allowed SYN packets per second. |
Burst Size | Defines the maximum number of matching entries in a single burst.
Tip:
We recommend that you set the burst size to be at least one tenth of the Allowed SYNs per Second value. If the burst size is too small, SYN rate limits do not work. For example, if the value for Allowed SYNs per Second is 10000, set the value for Burst Size to at least 1000. |
Enable Log Compression | Allows you to define the maximum number of separately logged entries.
For each event type,
Antispoofing or
Discard, you can define:
|
Set to Default | Returns all changes to the log compression settings to the default settings. |
Send IPv6 Router Advertisements | Select and specify what configuration information is offered in the Router Advertisement messages to devices that connect to the same network as the firewall. |
Managed address configuration | When selected, the router advertisement messages that the Firewall sends instruct the hosts to use the DHCPv6 protocol to acquire IP addresses and other configuration information. |
Other configuration | When selected, the router advertisement messages that the Firewall sends instruct the hosts to acquire the IPv6 prefix and the default route information from the router advertisement messages, and to use the DHCPv6 protocol to acquire other configuration information (such as DNS server addresses). |
