Option Definition
Policy for Layer 2 Interfaces

The Layer 2 Interface Policy that contains rules for traffic detected by layer 2 physical interfaces.

All layer 2 physical interfaces on the Secure SD-WAN Engine use the same Layer 2 Interface Policy. If there are no layer 2 physical interfaces, this setting is ignored.

Layer 2 Interface Settings section Defines settings for connection tracking on layer 2 physical interfaces.
Layer 2 Connection Tracking Mode

When connection tracking is enabled, reply packets are allowed as part of the allowed connection without an explicit Access rule.

You can override this engine-specific setting and configure connection tracking for TCP, UDP, and ICMP traffic in Access rules.

  • Normal — The engine drops ICMP error messages related to connections that are not currently active in connection tracking. A valid, complete TCP handshake is required for TCP traffic. The engine checks the traffic direction and the port parameters of UDP traffic.
  • Strict — The engine does not permit TCP traffic to pass through before a complete, valid TCP handshake is performed.
  • Loose — The engine allows some connection patterns and address translation operations that are not allowed in the Normal mode. This mode can be used, for example, if routing is asymmetric and cannot be corrected or if the use of dynamic routing protocols causes the engine to receive non-standard traffic patterns.
Inline IPS and Capture Interface Settings section Defines advanced settings for Inline IPS Interfaces and Capture Interfaces.
Bypass Traffic on Overload

When selected, the Secure SD-WAN Engine dynamically reduces the number of inspected connections if the load is too high.

Some traffic might pass through without any access control or inspection if this option is selected. Bypassed traffic is not counted when a possible license throughput limit is enforced. The bypass does not affect traffic subject to TLS Inspection.

If this option is not selected, the Secure SD-WAN Engine inspects all connections. Some connections might not get through if the engine gets overloaded.

Engine Editor > Interfaces > Interface Options

Use this branch to define which IP addresses are used in particular roles in the Secure SD-WAN Engine's system communications.

Option Definition
Control Interface

(Not Virtual Engines)

  • Primary — Specifies the Primary Control IP address for Management Server contact.
  • Backup (Optional) — Specifies the Backup Control IP address that is used if the Primary Control IP address is not available.
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 Engine.
Node-Initiated Contact to Management Server When selected, the Secure SD-WAN Engine opens a connection to the Management Server and maintains connectivity. This option is always used with a dynamic control IP address, so it is always selected if the control IP address is dynamic. If the connection is not open when you command the Secure SD-WAN Engine through the Management Client, the command is left pending until the Secure SD-WAN Engine opens the connection again.
Note: This option is not supported for IPS Clusters, Layer 2 Engine Clusters, or Virtual Secure SD-WAN Engines.
Heartbeat Interface

(Clusters and Master Engines only)

  • Primary — Specifies communications between the nodes. We recommend that you use a Physical Interface, not a VLAN Interface. We strongly recommend that you do not direct any other traffic through this interface. A dedicated network helps guarantee reliable and secure operation.
    CAUTION:
    Primary and Backup Heartbeat networks exchange confidential information. If dedicated networks are not possible, configure the cluster to encrypt the exchanged information.
  • Backup — Used if the Primary Heartbeat Interface is unavailable. It is not mandatory to configure a backup Heartbeat Interface, but we strongly recommend it. If heartbeat traffic is not delivered, the cluster cannot operate and traffic is interrupted. We strongly recommend that you use a dedicated interface for the backup heartbeat as well.

On Master Engines, you cannot use shared interfaces as a heartbeat interface.

IPv4 Identity for Authentication Requests or IPv6 Identity for Authentication Requests

The IPv4 address or IPv6 address of the selected interface is used when an Secure SD-WAN Engine contacts an external authentication server.

This option does not affect the routing of the connection with the authentication server. The IP address is used only as a parameter inside the authentication request payload to give a name to the request sender.

IPv4 Source for Authentication Requests or IPv6 Source for Authentication Requests By default, specifies the source IPv4 address or IPv6 address for authentication requests according to routing. If the authentication requests are sent to an external authentication server over VPN, select an interface with a Node Dedicated IP address that you want to use for the authentication requests.
Default IP Address for Outgoing Traffic Specifies the IP address that the Secure SD-WAN Engine uses to initiate connections (such as for system communications and ping) through an interface that has no Node Dedicated IP Address. In clusters, you must select an interface that has an IP address defined for all nodes.

Note: This option is an alternative to using virtual IP addresses for VPN Clients.

Engine Editor > Advanced Settings

Use this branch to change system parameters for the Secure SD-WAN Engine. These parameters control how the Secure SD-WAN Engine behaves under certain traffic conditions.

Option Definition
Encrypt Configuration Data By default, the configuration of the Secure SD-WAN Engine is stored in an encrypted format. Disable the encryption only if instructed to do so by Forcepoint Technical Support.
Disable Application Health Monitoring When selected, the Application Health Monitoring feature is disabled.
Bypass Traffic on Overload

(IPS only)

When selected, the Secure SD-WAN Engine dynamically reduces the number of inspected connections if the load is too high.

Some traffic might pass through without any access control or inspection if this option is selected. Bypassed traffic is not counted when a possible license throughput limit is enforced. The bypass does not affect traffic subject to TLS Inspection.

If this option is not selected, the Secure SD-WAN Engine inspects all connections. Some connections might not get through if the IPS engine gets overloaded.

Contact Node Timeout

(Not Virtual Engines)

The maximum amount of time the Management Server tries to connect to an Secure SD-WAN Engine.

A consistently slow network connection might require increasing this value. The default value is 120 seconds.

Note: Setting the timeout value too short or too long can delay or prevent contact between the Management Server and the Secure SD-WAN Engines.
Auto Reboot Timeout

(Not Virtual Engines)

Specifies the length of time after which an error situation is considered non-recoverable and the Secure SD-WAN Engine automatically reboots. The default value is 10 seconds. Set to 0 to disable.
Policy Handshake

(Not Virtual Engines)

When selected, the nodes automatically roll back to using the previously installed policy if connectivity is lost after installing a new policy.

Without this feature, you must switch to the previous configuration manually through the boot menu of the Secure SD-WAN Engine.

Note: We recommend adjusting the timeout (next setting) rather than disabling this feature completely if there is a need to make changes.
Rollback Timeout

(Not Virtual Engines)

The length of time the Secure SD-WAN Engine waits for a management connection before it rolls back to the previously installed policy when the Policy Handshake option is active. The default value is 60 seconds.
Automated Node Certificate Renewal

(Not Virtual Engines)

When selected, the Secure SD-WAN Engine's certificate for system communications is automatically renewed before it expires. Otherwise, the certificate must be renewed manually.

Each certificate for system communications is valid for three years. If the certificate expires, other components refuse to communicate with the Secure SD-WAN Engine.

Note: Does not renew SD-WAN certificates. Automatic certificate renewal for internally signed SD-WAN certificates is set separately in the Secure SD-WAN Engine's SD-WAN settings.
FIPS-Compatible Operating Mode

(Engines only)

(Not Virtual Engines)

When selected, activates a mode that is compliant with the Federal Information Processing Standards (FIPS).
Note: You must also select FIPS-specific settings in the Secure SD-WAN Configuration Wizard on the command line of the Secure SD-WAN Engine. For more information, see How to install Forcepoint FlexEdge Secure SD-WAN in FIPS mode.
Disable Remote Engine Upgrades

(FIPS-Compatible Operating Mode only)

When selected, remote upgrades for Secure SD-WAN Engines are disabled in FIPS-compatible operating mode.
Disable sgInfo Creation

(FIPS-Compatible Operating Mode only)

When selected, creating sgInfo files for Secure SD-WAN Engines is disabled in FIPS-compatible operating mode.
Number of CPUs Reserved for Control Plane

(Engines only)

(Not Virtual Engines)

Select how many CPUs to reserve for control plane operations. In situations where there is exceptionally high traffic, in a denial of service attack, for example, this ensures that you can still monitor and control the Secure SD-WAN Engine operation.
Note: The reserved CPUs cannot be used for traffic processing. Using fewer CPUs for traffic processing degrades performance.
Isolate Also Interfaces for System Communications

(Engines only)

When selected, the reserved CPUs handle the system communications traffic that pass through the Control Interfaces and dedicated primary Heartbeat Interfaces. We recommend that you only use this option when the Physical Interfaces used for system communications do not handle any other traffic.

Engine Editor > Advanced Settings > Traffic Handling

Use this branch to change advanced parameters that control how the Secure SD-WAN Engine handles traffic.

Option Definition
Layer 3 Connection Tracking Mode

(Engines only)

Connection Tracking Mode

(IPS engines and Layer 2 Engines only)

When connection tracking is enabled, reply packets are allowed as part of the allowed connection without an explicit Access rule.

You can override this Secure SD-WAN Engine-specific setting and configure connection tracking for TCP, UDP, and ICMP traffic in Access rules.

  • Normal — The Secure SD-WAN Engine drops ICMP error messages related to connections that are not currently active in connection tracking. A valid, complete TCP handshake is required for TCP traffic. The Secure SD-WAN Engine checks the traffic direction and the port parameters of UDP traffic.
  • Strict — The Secure SD-WAN Engine does not permit TCP traffic to pass through before a complete, valid TCP handshake is performed.
  • Loose — The Secure SD-WAN Engine allows some connection patterns and address translation operations that are not allowed in the Normal mode. This mode can be used, for example, if routing is asymmetric and cannot be corrected or if the use of dynamic routing protocols causes the Secure SD-WAN Engine to receive non-standard traffic patterns.
On Engines and Layer 2 Engines, Normal is the default setting. On IPS engines, Loose is the default setting.
Virtual Defragmenting

(Not Virtual Engines)

(Not editable on IPS engines)

When selected, fragmented packets are sent onwards using the same fragmentation as when they arrived at the Secure SD-WAN Engine.

When the Secure SD-WAN Engine receives fragmented packets, it defragments the packets for inspection. The original fragments are queued until the inspection is finished. If the option is not selected, the packets are sent onwards as if they had arrived unfragmented.

Strict TCP Mode for Deep Inspection

(Not Virtual Engines)

This option is included for backward compatibility with legacy software versions.
Concurrent Connection Limit

(Not Virtual Engines)

A global limit for the number of open connections. When the set number of connections is reached, the Secure SD-WAN Engine stops the next connection attempts until a previously open connection is closed.
Inspection CPU Balancing Mode

(Not Virtual Engines)

Specifies how inspected connections are allocated between the CPUs. Select from the following options:
  • Default — The connection is allocated to the CPU that received the first packet of the connection. If the utilization on the CPU is high, a different CPU is dynamically selected. Incoming and outgoing packets might be handled by different CPUs.
  • Round Robin — Connections are allocated evenly between all CPUs in order. This option can improve CPU balancing when there are a large number of CPUs.
  • NUMA local Round Robin — Connections are balanced within the CPU that received the first packet of the connection. Incoming and outgoing packets are handled by the same CPU.
Active Wait Time Between Inspected Packets

(Not Virtual Engines)

Defines how long the inspection process stays active waiting for packets after it has inspected a packet.
  • Short — The inspection process stays active for the minimum amount of time. This setting provides the best CPU performance, but can increase latency in inspection. This is the default setting.
  • Medium — The inspection process stays longer for a moderate amount of time. This setting provides a balance between CPU performance and latency in inspection.
  • Long — The inspection process stays active for the maximum amount of time. This setting provides the lowest latency in inspection, but decreases CPU performance.
Default Connection Termination in Access Policy

(IPS engines and Layer 2 Engines only)

Defines how connections that match Access rules with the Discard action are handled.
  • Terminate and Log Connection — Stops the matching connections. This option is the default setting.
  • Only Log Connection — Does not stop the matching connections. Creates a Terminate (passive) log entry for the matching connections. This option is useful for testing which types of connections are stopped.
Default Connection Termination in Inspection Policy Defines how connections that match rules with the Terminate action in the Inspection Policy are handled.
  • Terminate and Log Connection — Stops the matching connections. This option is the default setting.
  • Only Log Connection — Does not stop the matching connections. Creates a Terminate (passive) log entry for the matching connections. This option is useful for testing which types of connections are stopped.
Action When TCP Connection Does Not Start With a SYN Packet

(Not Master Engines)

The Secure SD-WAN Engine refuses TCP connections if the TCP connection does not start with a SYN packet, even if the TCP connection matches an Access rule with the Allow action. The Secure SD-WAN Engine does not send a TCP reset if the TCP connection begins with a TCP reset packet.
  • Discard Silently — The connection is silently dropped.
  • Refuse With TCP Reset — The connection is refused, and a TCP reset packet is returned.

Engine Editor > Advanced Settings > Certificate Validation

Use this branch to specify settings for certificate validation and revocation status checks on the engine. The settings are used for features that have certificate validation and certificate revocation checks enabled.

Note: These settings are not supported for Virtual Engines.
Option Definition
HTTP Proxy

(Optional)

When specified, OCSP and CRL lookups are sent through an HTTP proxy instead of the engine accessing the external network directly.
Timeout for OCSP and CRL Lookups The maximum amount of time that the engine tries to connect to the CRL or OCSP server if the connection has failed. The default is 120 seconds.
Active destination server certificate probing When selected, it enables the Secure SD-WAN Engine to fetch the server certificate over a separate TLS connection before establishing the original connection.
Server certificate cache timeout The set value for this field determines how long the previously fetched certificates are to be retained.

Engine Editor > Advanced Settings > SYN Rate Limits

Use this branch to change global SYN rate limits. SYN rate limits reduce the risk of SYN flood attacks.

Option Definition
SYN Rate Limits Limits for SYN packets sent to the Secure SD-WAN Engine.
  • None — SYN rate limits are disabled.
  • Automatic — The Secure SD-WAN Engine automatically calculates the Allowed SYNs per Second and Burst Size values for the interface based on the Secure SD-WAN Engine capacity and memory size.
  • Custom — Enter custom values for Allowed SYNs per Second and Burst Size.
Allowed SYNs per Second

(When SYN Rate Limits is Custom)

The number of allowed SYN packets per second.
Burst Size

(When SYN Rate Limits is Custom)

The number of allowed SYNs before the Secure SD-WAN Engine starts limiting the SYN rate.
CAUTION:
We recommend setting the Burst Size value to 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, the Burst Size value must be at least 1000.

Engine Editor > Advanced Settings > Log Handling

Use this branch to change log handling settings for the Secure SD-WAN Engine. You can use log handling settings to adjust logging when the log spool fills up.

Note: These settings are not supported for Virtual Engines.
Option Definition
Log Spooling Policy

(Not Virtual Engines)

Defines what happens when the log spool becomes full.
  • Stop Traffic — The Secure SD-WAN Engine stops processing traffic and goes offline.
  • Discard Log — Log entries are discarded in four stages, according to available space. Monitoring data is discarded first, followed by log entries marked as Transient and Stored, and finally log entries marked as Essential. The Secure SD-WAN Engine continues to process traffic.
Log Compression

(Antispoofing Log Event Type for Engines only)

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. The individual log entries are deleted. After the single log entry is created, logging returns to normal and all entries are logged and shown separately. Double-click a cell to edit the value.
Note: Do not enable Log Compression if you want all Antispoofing and Discard entries to be logged as separate log entries (for example, for reporting or statistics).
Set to Default Returns Log Compression settings to the default settings.
Store a Copy of Recent Log Files on the Secure SD-WAN Engine When selected, the Secure SD-WAN Engine stores copies of logs according to the specified settings.
Maximum Time The maximum length of time for which to store copies of logs. Values can be 1–720 hours (the maximum is 30 days), or not specified. If a value is not specified, the Secure SD-WAN Engine stores copies of logs until the limits specified in the Guaranteed Free Spool Partition or Guaranteed Free Spool Partition Size options are reached.
Guaranteed Free Spool Partition The minimum percentage of the spool partition that must be kept free. When the amount of free space reaches the limit, the Secure SD-WAN Engine starts deleting the oldest stored copies of log and alert entries when a new log or alert entry is saved. Values can be 5–80 %, or not specified.
Note: You must enter a value for at least one of the guarantee options. If you enter a value for both options, both limits are enforced.
Guaranteed Free Spool Partition Size The minimum amount of file space, in MB, on the spool partition that must be kept free. When the amount of free space reaches the limit, the Secure SD-WAN Engine starts deleting the oldest stored copies of log and alert entries when a new log or alert entry is saved. Values can be 50–1000 MB, or not specified.
Note: You must enter a value for at least one of the guarantee options. If you enter a value for both options, both limits are enforced.

Engine Editor > Advanced Settings > Scan Detection

  • Stored — Creates a log entry that is stored on the Log Server.
  • Essential — Creates a log entry that is shown in the Logs view and saved for further use.
  • Alert — Triggers the alert you select.
Alert When the Log Level is set to Alert, specifies the Alert that is sent.
Severity When the Log Level is set to Alert, allows you to override the severity defined in the Alert element.
Set to Default Returns Scan Detection changes to the default settings.

Engine Editor > Advanced Settings > DoS Protection

Use this branch to configure protection that can help prevent Denial of Service (DoS) attacks.

Option Definition
Rate-Based DoS Protection Mode Enables or disables DoS protection, which can help prevent Denial of Service (DoS) attacks.
  • Disabled — DoS protection is not enabled.
  • Off (Can Be Overridden in Policy) — DoS protection is not enabled, but you can override this setting in individual Access rules. This option is the default setting.
  • On (Can Be Overridden in Policy) — DoS protection is enabled. You can override this setting in individual Access rules.
SYN Flood Sensitivity When SYN flood protection is activated, the Secure SD-WAN Engine acts as a SYN proxy. The engine completes the TCP handshake with the client, and only initiates the connection with the server after the client has completed the TCP handshake.
  • Off — SYN flood protection is not enabled.
  • Low — Allows the most SYN-ACK timeouts before the Secure SD-WAN Engine requires a full TCP handshake with the client before it communicates with a server.
  • Medium — Allows a medium number of SYN-ACK timeouts before the Secure SD-WAN Engine requires a full TCP handshake with the client before it communicates with a server. This option is the default setting.
  • High — Allows the fewest SYN-ACK timeouts before the Secure SD-WAN Engine requires a full TCP handshake with the client before it communicates with a server.
Limit for Half-Open TCP Connections

(Optional)

Set the maximum number of half-open TCP connections per destination IP address. The minimum is 125, the maximum is 100 000. When the limit is exceeded, the SYN flood protection is activated, and log data is generated.
Slow HTTP Request Sensitivity The Secure SD-WAN Engine analyzes the data transfer rate and length of time it takes to read the header fields of the HTTP request. If the sender of the request tries to keep the connection open for an unreasonable length of time, the Secure SD-WAN Engine block lists the sender’s IP address for a specified length of time.
  • Off — Slow HTTP Request Protection is not enabled.
  • Low — Allows the slowest data transfer rate before the block list timeout is applied. This option is the default setting.
  • Medium — Allows a moderately slow data transfer rate before the block list timeout is applied.
  • High — Allows the least slow data transfer rate before the block list timeout is applied.
Slow HTTP Request Block list Timeout The length of time for block listing IP addresses that are suspected of sending malicious traffic. Enter the time in seconds (the default is 300).
TCP Reset Sensitivity When enabled, the Secure SD-WAN Engine detects the sequence numbers of the TCP RST segments to determine whether it is under a TCP Reset attack. You cannot override this setting in individual Access rules
  • Off — TCP reset protection is not enabled. This option is the default setting.
  • Low — Allows the most TCP reset requests before the Secure SD-WAN Engine considers itself to be under attack.
  • Medium — Allows a medium number of TCP reset requests before the Secure SD-WAN Engine considers itself to be under attack.
  • High — Allows the fewest TCP reset requests before the Secure SD-WAN Engine considers itself to be under attack.

Note: This setting applies to all user authentication, including browser-based user authentication, VPN clients, and the SSL VPN Portal.
Allow user lookup from known User Domain matching to client certificate email domain or UPN suffix When selected, the Secure SD-WAN Engine looks up the user from the domain specified in the email address or user principal name before looking up the user in the default domain.
Note: This option is ignored when the value of the Client Certificate Identity Field for TLS option is Distinguished Name.
Client Certificate Identity Field for TLS The attribute that is used to look up the user entry from the user domain when using TLS. The Secure SD-WAN Engine only uses values from the Active Directory or LDAP server that is associated with the global default LDAP domain or the engine-specific default user domain.
  • User Principal Name — The User Principal Name attribute on the Attributes tab of the Active Directory Server or LDAP Server element is used.
  • Email — The E-mail attribute on the Attributes tab of the Active Directory Server or LDAP Server element is used.
  • Distinguished Name — The specified value in the distinguished name is used.
    Note: If you select Distinguished Name, you must specify the identity search value on the Client Certificate tab of the Active Directory Server or the LDAP Server Properties dialog box.

Engine Editor > Advanced Settings > Tunneling

Use this branch to change the packet tunneling settings for the engine.

Option Definition
Limit for Rematching Tunneled Traffic Specifies how many times the contents of tunneled packets can be re-matched against the IPv6 Access rules or IPv4 Access rules when several layers of tunneling are encountered. The default is 1. When the limit is reached, the action defined in the Action if Limit is Exceeded setting is taken.
Action if Limit is Exceeded Specifies whether remaining encapsulated packets inside the tunneling packet are allowed without further inspection or discarded. The default is to discard the remaining packets. When this action is triggered, you are notified according to the Log Level setting.
Log Level Specifies whether you are notified through a normal (stored) log entry or an Alert when the limit for rematching tunneled traffic is reached.
Alert If you selected Alert as the Log Level, select the Alert element that is used when an event triggers an alert. The Alert elements can be used for matching in Alert Policies. Click Select to select an element.
