NGFW Online Help

Home
Routing
Use the Management Client to configure static or dynamic routing, and use a Multi-Link configuration to manage and distribute inbound and outbound connections.
Outbound traffic management
You can use Multi-Link to distribute outbound traffic between multiple network connections and to provide High Availability and load balancing for outbound traffic.
Getting started with outbound traffic management
Multi-Link for SD-WAN provides high availability for outbound connectivity so that business-critical traffic gets through even when one or more Internet connections fail.
Using Multi-Link with a Single Firewall for outbound traffic management
You can configure Multi-Link with Single Firewalls where each interface is connected to a router from a different ISP.

Introduction to the Forcepoint Next Generation Firewall solution
Before setting up Forcepoint Next Generation Firewall (Forcepoint NGFW), it is useful to know what the different components do and what engine roles are available.
Deployment
Before you can set up the system and start configuring elements, you must consider how the different SMC components should be positioned and deployed.
Setting up
After deploying the SMC components, you are ready to start using the Management Client and carrying out some of the first configuration tasks.
Monitoring
You can use the SMC to monitor system components and third-party devices. You can also view and filter logs, and create Reports from them.
Controlling engines
You can command and set options for engines through the Management Client or on the engine command line. You can also stop traffic manually.
SMC configuration
Security Management Center (SMC) configuration allows you to customize how the SMC components work.
Engine element configuration
You can create and modify Firewalls, IPS engines, Layer 2 Firewalls, Master NGFW Engines and Virtual NGFW Engines. You can configure the engine properties, activate optional features, and configure advanced engine settings.
Routing
Use the Management Client to configure static or dynamic routing, and use a Multi-Link configuration to manage and distribute inbound and outbound connections.
- Configuring routing and antispoofing
  Routing defines through which next hop router the NGFW Engine forwards traffic from a source address to a destination address. Antispoofing defines which addresses are considered valid source addresses for the networks connected to each interface.
- Configuring dynamic routing
  With dynamic routing, NGFW Engines automatically change their routing when the network topology changes. The NGFW Engines can also exchange information about appropriate routing paths.
- Outbound traffic management
  You can use Multi-Link to distribute outbound traffic between multiple network connections and to provide High Availability and load balancing for outbound traffic.
  - Getting started with outbound traffic management
    Multi-Link for SD-WAN provides high availability for outbound connectivity so that business-critical traffic gets through even when one or more Internet connections fail.
    - Outbound traffic management configuration overview
      Outbound traffic management is configured using NetLink elements, which represent network connections.
    - Using standby NetLinks for High Availability in outbound traffic management
      Standby NetLinks allow you to define a NetLink as a backup that is only activated when all primary NetLinks are unavailable.
    - Using Multi-Link with a Single Firewall for outbound traffic management
      You can configure Multi-Link with Single Firewalls where each interface is connected to a router from a different ISP.
    - Using Multi-Link with a Firewall Cluster for outbound traffic management
      You can configure Multi-Link with a Firewall Cluster consisting of two nodes by using two routers and two switches and physically connecting each node to each switch.
  - Defining Multi-Link routes
    When you use Multi-Link routing, traffic is routed through different network connections according to traffic conditions, the availability of the different connections, and the preferences that you configure.
  - Configuring outbound Multi-Link settings
    Outbound Multi-Link elements combine NetLinks and set options for the high availability and load balancing features.
  - Create outbound load-balancing NAT rules
    To balance outbound connections between the NetLinks, define NAT rules using the source NAT addressing defined in the Outbound Multi-Link element.
  - Monitoring and testing outbound traffic management
    You can monitor the status of the NetLinks in the SD-WAN Dashboard in the Home view. NetLinks are shown as ISP connections.
  - Examples of Multi-Link
    Multi-Link technology has many uses, some of which might apply to your situation.
- Inbound traffic management
  Inbound traffic management ensures that services remain available even when one or more servers or NetLinks fail, and balances the load of incoming traffic more efficiently between a group of servers. Inbound traffic management is not supported on Layer 2 Firewalls or on layer 2 physical interfaces on Firewalls.
Traffic inspection policies
Policies are key elements that contain rules for allowing or blocking network traffic and inspecting the content of traffic.
Users and authentication
User accounts are stored in internal databases or external directory servers. You can use Forcepoint NGFW in the Firewall/VPN role or external authentication servers to authenticate users.
Virtual private networks
Forcepoint NGFW supports both policy-based and route-based VPNs (virtual private networks).
Maintenance and upgrades
Maintenance includes procedures that you do not typically need to do frequently.
Troubleshooting
Troubleshooting helps you resolve common problems in the Forcepoint NGFW and SMC.
