NGFW 6.7 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.
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.
Examples of routing configuration
The SMC provides features that allow you to configure many routing scenarios.

About this Help
This online Help was created for Forcepoint Next Generation Firewall (Forcepoint NGFW), version 6.7.0.
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 NGFW 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.
NGFW Engine configuration
You can create and modify Firewalls, IPS engines, Layer 2 Firewalls, Master NGFW Engines and Virtual NGFW Engines. You can configure the NGFW Engine properties, activate optional features, and configure advanced NGFW 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.
  - Getting started with routing
    To understand how the NGFW Engine reads routing definitions, look at the network interfaces in the routing or antispoofing configurations.
  - Routing configuration overview
    Routing configuration involves adding a default route, adding routes to networks that are not directly connected, and adding routes to networks that can be reached through route-based VPNs.
  - Add routers
    A Router element represents a next-hop gateway’s IP address in routing configurations.
  - Add or view the default route
    You can check which route is currently set as the default route for traffic leaving the NGFW Engine and set a new default route.
  - Add static routes
    You can add a static route to a network in the routing configuration.
  - Using metrics or ECMP on multiple routes to the same destination
    You can configure multiple routes through different next hop gateways to the same destination.
  - Configuring multicast routing
    The NGFW Engine supports static multicast, IGMP-based multicast forwarding (IGMP proxying), and multicast routing using protocol-independent multicast (PIM). You can also configure dynamic multicast routing using the Quagga Routing Suite on the command line.
  - Configure policy routing
    Policy routing allows you to route traffic based on both source and destination IP address. Policy routing is useful when you want to configure a different route for a destination based on the source address.
  - Configure DHCP message routing
    The firewall can relay DHCP messages. If DHCP messages are routed through the firewall (from a network segment to some other, isolated segment), you must enable DHCP relay on the firewall interface properties for the interface where the DHCP requests are originating from (client’s network).
  - Check routes using the Route Query tool
    The Route Query tool allows you to check where packets with a certain IP address are routed according to the current definitions. You can check that the routing is correct and quickly find a particular branch in the Routing tree.
  - Remove static routes
    New networks are automatically added to routing when you change the properties of an interface. However, the Networks are not automatically removed, so you must check the routing configuration for obsolete entries and remove them manually.
  - Modifying antispoofing
    IP address spoofing is an attack where the source IP address in a packet is changed to gain unauthorized access or to cause a denial-of-service. Such attacks can be prevented with antispoofing rules.
  - Examples of routing configuration
    The SMC provides features that allow you to configure many routing scenarios.
    - Examples of route selection and antispoofing definitions
      There are several considerations to take into account when configuring routing and antispoofing.
    - Example: Routing traffic with two interfaces
      To route traffic to two interfaces, add a router for each interface.
    - Example: Using policy routing to route traffic to networks that use the same address space
      To manage traffic to networks that share the same address space, create a policy routing entry for each host.
- 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.
- 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 VPN (virtual private network) tunnels between VPN gateways. For full remote access, Forcepoint NGFW 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 Forcepoint NGFW and SMC.
