Steps
Engine Editor > General > SNMP and LLDP
Use this branch to enable the NGFW Engine to send SNMP traps and to select the LLDP Profile for the NGFW Engine.
Option | Definition |
---|---|
SNMP section | |
SNMP Agent | Enables the NGFW Engine to send SNMP traps.
|
SNMP Location | Specifies the SNMP location string that is returned on queries to the SNMPv2-MIB or SNMPv2-MIB-sysLocation object. |
SNMP Engine ID (Single NGFW Engines and SNMPv3 only) |
A unique identifier for the NGFW Engine that is used by the SNMP agent. The engine ID is used with a hash function to generate keys for authentication and encryption of SNMPv3 messages. If you do not specify the SNMP engine ID, an SNMP engine ID is automatically generated. |
Listening IP Addresses | The IPv4 or IPv6 addresses from which SNMP traps are sent. Click Add to add an element to the list, or Remove to remove the selected element. |
LLDP section | |
LLDP Profile (NGFW Engines and Master NGFW Engines in the Firewall/VPN role only) |
The LLDP Profile element that specifies settings for LLDP announcements that the NGFW Engine announces. Click Select to select an element. |
Layer 3 Physical Interface Properties dialog box (Firewall)
Use this dialog box to define the Layer 3 Physical Interface properties for a Single Firewall or Firewall Cluster.

General tab | |
Interface ID | The Interface ID automatically maps to a physical network port of the same number during the initial configuration of the NGFW Engine. The mapping can be changed as necessary through command-line tools. Note: For Master NGFW Engines, changes to the interface mapping do not affect the Interface IDs that are defined for Virtual NGFW Engines in Virtual Resource
elements.
|
Type |
Note: We recommend that you do not use the IP address of an Aggregated Link interface as the primary or secondary control IP address of the NGFW Engine.
|
Second Interface ID | (When Type is Aggregated Link in High Availability Mode) The second interface in the aggregated link for high availability Mode. |
Additional Interface(s) | (When Type is Aggregated Link in Load Balancing Mode) Lists interfaces that you have added for an aggregated link. Click Add to add a row to the table, or Remove to remove the selected row. |
MTU
(Optional) |
The maximum transmission unit (MTU) size on the connected link. Either enter a value between 400–65535 or select a common MTU value from the list. If the interface is a Physical Interface, the same MTU is automatically applied to any VLANs created under it. The default value (also the maximum standard MTU in Ethernet) is 1500. Do not set a value larger than the standard MTU, unless you know that all devices along the communication path support it. To set the MTU for a Virtual NGFW Engine, you must configure the MTU for the interface on the Master NGFW Engine that hosts the Virtual NGFW Engine, then refresh the policy on the Master NGFW Engine and the Virtual NGFW Engine. |
LLDP Mode | Specifies how LLDP is used on the interface.
|
Comment (Optional) |
A comment for your own reference. |
Option | Definition |
---|---|
Clustering section (Optional) (Firewall Clusters only) |
|
CVI Mode
(Optional) |
Note: Unless you have a specific reason to use some other setting, use the default Packet Dispatch setting. The Packet
Dispatch mode is the best choice in most environments.
|
MAC Address | Enter a MAC address for the Cluster Virtual IP Address. Do not use the MAC address of any actual network card on any of the nodes. |
Multicast Address | (When CVI Mode is Multicast with IGMP) Enter a multicast address. |
Option | Definition |
---|---|
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 |
(When QoS Mode is Full QoS or DSCP Handling and Throttling) 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 |
(When QoS Mode is Full QoS) 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.

DHCPv4 tab, DHCPv4 Server settings (When DHCP Mode is DHCPv4 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 DHCP Ranges per Node
(Firewall Clusters only) |
Enter the DHCP address range for each node. CAUTION: Enter unique ranges for each node. Overlapping ranges can cause IP address duplication.

Advanced tab (All optional settings) |
|
Override Engine's Default Settings | When selected, the default settings of the NGFW Engine are overridden. |
SYN Rate Limits |
|
Allowed SYNs per Second | Defines the number of allowed SYN packets per second. |
Burst Size | The number of allowed SYNs before the NGFW Engine starts limiting the SYN rate. 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 | By default, each generated Antispoofing and Discard log entry is logged separately and displayed as a separate entry in the Logs view. Log Compression settings allow you to define the maximum number of separately logged entries. When the defined limit is reached, a single antispoofing log entry or Discard log entry is logged. The single entry contains information about the total number of the generated Antispoofing log entries or Discard log entries. After this log entry, the logging returns to normal and all generated entries are once more logged and displayed separately. Log Compression is useful when the routing configuration generates a large volume of antispoofing logs or the number of Discard logs becomes high. 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 |
When selected, the firewall offers configuration information in Router Advertisement messages to devices that connect to the same network as the firewall.
This option is selected by default when there is an IPv6 address on the interface. |
Include Prefix Information Option |
When selected, router advertisement messages include the prefix option. Only available when Send IPv6 Router Advertisements is selected. This option is selected by default when there is an IPv6 address on the interface. |
Set autonomous address-configuration Flag |
When selected the prefix option is sent with the autonomous address-configuration flag set to 1. Only available when Include Prefix Information Option is selected. This option is selected by default when there is an IPv6 address on the interface. |
Detect Duplicate IPv6 Addresses |
When selected, the firewall uses neighbor solicitation messages to detect the use of duplicate IPv6 addresses in directly connected networks. |
