Introduction to the Forcepoint FlexEdge Secure SD-WAN solution
Before setting up Forcepoint FlexEdge Secure SD-WAN, it is useful to know what the different components do and what engine roles are available.
- The Forcepoint FlexEdge Secure SD-WAN solution
  The Secure SD-WAN solution consists of one or more Secure SD-WAN Engines and the Forcepoint FlexEdge Secure SD-WAN Manager. The SMC is the management component of the Secure SD-WAN solution.
- Introduction to Secure SD-WAN in the Engine/VPN role
  Secure SD-WAN Engine in the Engine/VPN role provides access control and VPN connectivity.
- Introduction to Secure SD-WAN in the IPS and Layer 2 Engine roles
  The Secure SD-WAN Engines in the IPS and Layer 2 Engine roles are part of the Secure SD-WAN solution. The IPS component provides intrusion detection and prevention, and the Layer 2 Engines provide access control and deep inspection of traffic.
  - What IPS engines and Layer 2 Engines do
    An IPS engine or a Layer 2 Engine picks up and examines network traffic in real time. Layer 2 Engines and IPS engines perform event correlation and analysis for traffic they inspect.
  - How IPS engines and Layer 2 Engines respond to incidents
    There are various responses that an IPS engine and a Layer 2 Engine can take when it detects traffic of interest. For example, they can log the connection or actively filter out the traffic.
  - Main benefits of IPS engines and Layer 2 Engines
    IPS engines and Layer 2 Engines have four key benefits: accuracy, manageability, scalability, and high availability.
    - Accuracy of IPS engines and Layer 2 Engines
      To provide the best possible accuracy, the IPS and Layer 2 Engines provide multiple detection methods that complement each other.
    - Manageability of IPS engines and Layer 2 Engines
      IPS engines and Layer 2 Engines provide network administrators the tools to save time, reduce mistakes, and get a network overview.
    - Scalability and high availability of IPS engines and Layer 2 Engines
      Scalability and high availability guarantee that the system can adapt to growing needs, simplify planned maintenance, and protect against hardware failure. IPS engines and Layer 2 Engines can be flexibly scaled up to form clusters of up to 16 devices that work as a single virtual entity.
  - IPS Cluster load balancing
    In a load-balanced cluster, traffic is dynamically balanced between the nodes.
  - Disconnect mode for IPS engines and Layer 2 Engines and how it works
    IPS engines and Layer 2 Engines support disconnect mode, which enables constant monitoring of link connections and minimizes delays caused by link failures.
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 Secure SD-WAN 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
SD-WAN Manager configuration allows you to customize how the SMC components work.
Secure SD-WAN Engine configuration
You can create and modify Engines, IPS engines, Layer 2 Engines, Master Engines and Virtual Secure SD-WAN Engines. You can configure the Secure SD-WAN Engine properties, activate optional features, and configure advanced Secure SD-WAN 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.
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 Secure SD-WAN in the Engine/VPN role or external authentication servers to authenticate users.
Virtual private networks
Secure SD-WAN supports both policy-based and route-based VPN tunnels between VPN gateways. For full remote access, Secure SD-WAN supports both IPsec and SSL VPN tunnels for VPN clients.
Maintenance and upgrades
Maintenance includes procedures that you do not typically need to do frequently.
Troubleshooting
Troubleshooting helps you resolve common problems in the Secure SD-WAN and SMC.
