FortiGate-101F: The Ultimate Guide to SD-WAN Setup

The FortiGate 101F is a highly advanced next-gen firewall that offers a host of security features to protect your network. One of its standout features is its SD-WAN (Software-Defined Wide Area Network) capability. With SD-WAN, businesses can improve the efficiency of their networks, optimize traffic routing, reduce costs, and enhance security across geographically dispersed locations. In this guide, we’ll dive into the FortiGate-101F's SD-WAN setup, its benefits, and how to configure it to maximize your network’s performance.

What is SD-WAN and How Does It Work?

SD-WAN is a modern approach to network connectivity that leverages software to intelligently route traffic across a wide area network (WAN). Unlike traditional WANs, SD-WAN allows for centralized control and optimization of network traffic based on real-time conditions. This can result in improved bandwidth utilization, better application performance, reduced costs, and more robust security.

FortiGate-101F supports SD-WAN features that allow businesses to efficiently manage their network traffic and security while reducing dependency on expensive MPLS (Multiprotocol Label Switching) lines. Instead, SD-WAN allows businesses to prioritize critical applications, balance network traffic, and ensure a reliable and secure user experience.

Step-by-Step Guide to Setting Up FortiGate-101F SD-WAN

Setting up FortiGate-101F’s SD-WAN is straightforward, and the device comes with a user-friendly interface. Below is a step-by-step guide to setting up SD-WAN on your FortiGate-101F:

Step 1: Access the FortiGate Management Console

First, you need to log into the FortiGate Management Console through the web-based GUI. The IP address of the FortiGate device can be accessed from a web browser using the FortiGate’s default IP address.

Step 2: Enable SD-WAN

Navigate to Network > SD-WAN.

Click on Create New to add the SD-WAN configuration.

Enable SD-WAN by selecting the Enable SD-WAN checkbox.

Step 3: Configure SD-WAN Interfaces

You will need to configure the WAN interfaces that will be part of the SD-WAN setup:

Go to Network > Interfaces and assign interfaces to the SD-WAN category (e.g., WAN1, WAN2, LTE, etc.).

Ensure that all required interfaces have appropriate IP addresses and are active.

Step 4: Set WAN Interface Rules

Define policies that determine how traffic should be routed across different WAN interfaces. Use Application Rules to prioritize critical business applications and Performance SLA to monitor real-time metrics such as latency, jitter, and packet loss for each WAN interface.

Rule Type

Description

Performance SLA

Set thresholds for each WAN interface, such as maximum latency or jitter allowed before the traffic is re-routed.

Application-Based Routing

Define specific rules for high-priority applications to ensure they get the necessary bandwidth.

Step 5: Set Up Security and Monitoring

Enable FortiGuard services to get real-time threat intelligence and ensure the SD-WAN is secured against attacks.

Enable traffic monitoring to analyze real-time performance and bandwidth utilization.

Step 6: Test and Validate the Configuration

Once the SD-WAN setup is complete, you should test the configuration to ensure it’s working correctly. You can use the Real-Time Monitor to check if the traffic is being routed as expected and if any performance issues are detected.

SD-WAN Performance Metrics

The FortiGate-101F allows you to monitor and analyze network performance in real-time. Here are some common SD-WAN metrics you can track:

Metric

Description

Latency

Measures the delay between sending and receiving data across the network.

Packet Loss

Tracks the percentage of packets lost during transmission, which can affect application performance.

Jitter

Measures the variation in packet arrival times, which can impact real-time services like VoIP.

Bandwidth Utilization

Tracks how much of the available bandwidth is being used at any given time.

Path Quality

Monitors the health and reliability of each WAN path, determining the best route for different types of traffic.
