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.
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.
- Configuring routing and antispoofing
  Routing defines through which next hop router the Secure SD-WAN 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, Secure SD-WAN Engines automatically change their routing when the network topology changes. The Secure SD-WAN 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 VPN provides high availability for outbound connectivity so that business-critical traffic gets through even when one or more Internet connections fail.
  - Defining Multi-Link routes
    When you use Multi-Link routing, traffic can use multiple network connections to reach its destination.
  - Enable outbound traffic management using element-based NAT
    When you use element-based NAT for outbound traffic management, an Outbound Multi-Link element is automatically created based on the routing configuration.
  - Manually configuring outbound traffic management
    Outbound Multi-Link elements combine NetLinks and set options for the high availability and load balancing features.
  - Monitoring and testing outbound traffic management
    You can monitor the status of the NetLinks in the SD-WAN Dashboard. NetLinks are shown as ISP connections.
  - Examples of manually configuring Multi-Link
    Multi-Link technology has many uses, some of which might apply to your situation.
    - Example: Using Multi-Link to prepare for ISP downtime
      This scenario shows an example of using Multi-Link to configure connections to two ISPs. This configuration guarantees connectivity if one ISP fails.
    - Example: Excluding NetLinks from handling a QoS Class of traffic
      Using Multi-Link technology and QoS classes, you can exclude VoIP traffic from a satellite connection.
    - Example: Balancing traffic according to link capacity
      To manage ISP connections having very different bandwidths, you configure an Outbound Multi-Link element and select ratio load balancing.
    - Example: Balancing traffic between Internet connections
      This scenario shows an example of using Multi-Link to balance the load of traffic between two smaller Internet connections instead of one larger connection.
- 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 Engines or on layer 2 physical interfaces on Engines.
- Dynamic link selection
  When you use Multi-Link for outbound traffic management or Multi-Link VPNs, Secure SD-WAN in the Engine/VPN role can dynamically select the NetLink or VPN link that best matches the quality requirements of traffic.
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.
