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.
  - Overview of Secure SD-WAN in the Engine/VPN role
    Secure SD-WAN in the Engine/VPN role provides access control and VPN connectivity.
  - Secure SD-WAN benefits
    In addition to standard engine features, the Secure SD-WAN provides additional advanced features.
    - Support for multi-layer inspection
      Multi-layer inspection combines access control, application identification, deep inspection, and file filtering flexibly to optimize security and system performance.
    - Layer 2 interfaces for Secure SD-WAN in the Engine/VPN role
      Layer 2 interfaces on Secure SD-WAN Engines in the Engine/VPN role allow the Secure SD-WAN Engine to provide the same kind of traffic inspection that is available for Secure SD-WAN Engines in the IPS and Layer 2 Engine roles.
    - Advanced traffic inspection
      The Engine's traffic inspection process is designed to ensure a high level of security and throughput. The Engines’ policies determine when to use stateful connection tracking, packet filtering, or application-level security.
    - Built-in clustering for load balancing and high availability
      The Engine provides innovative built-in clustering and load-balancing features that provide several benefits over traditional solutions.
    - SD-WAN Capability
      Secure SD-WAN supports software-defined wide area networks (SD-WANs).
    - Built-in inbound traffic management
      The built-in Server Pool feature allows Engines to monitor a pool of alternative servers that offer the same service to the users.
    - Integrating Engine/VPN with IPS and Layer 2 Engines
      You can use Secure SD-WAN in the Engine/VPN, IPS, and Layer 2 Engine roles together for traffic inspection.
- 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.
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.
