Introduction 

Testing your internet speed is crucial for ensuring your network is performing optimally. Fortinet’s FortiGate makes this process straightforward. In this guide, we’ll walk you through the steps to perform a speed test using both the GUI and CLI methods. 

Step-by-Step Guide for Speed Testing with FortiGate 

1. Access the FortiGate GUI 

  • Open your preferred web browser. 
  • Enter the IP address of your FortiGate device in the address bar. 
  • Log in using your admin credentials. 

2. Navigate to Network Interfaces 

  • Once logged in, go to the Network section in the main menu. 
  • Click on Interfaces to view all network interfaces. 

3. Select the WAN Interface 

  • Identify and select the WAN interface you want to test. 
  • Click on the Edit button (usually represented by a pencil icon). 

4. Execute the Speed Test 

  • In the interface settings, look for the Execute speed test option. 
  • Click on it to start the speed test. This will measure your current internet speed. 

5. Apply Results 

  • After the test completes, you will see the results displayed. 
  • Click on Apply results to update the estimated bandwidth fields with the new data. 

6. Verify Connection to FortiGuard 

  • Ensure your FortiGate device is connected to FortiGuard. 
  • Verify that it can reach the AWS or Google speed test servers. This is crucial for accurate results. 

7. Easy Access to Results 

Test results can be incorporated into the interface’s estimated bandwidth. An SD-WAN network monitor license is needed. The License widget and the System -> FortiGuard page will show the status of this license. 

Advanced Users: CLI Method 

For those comfortable with command-line interfaces, the CLI method offers more control and flexibility. 

1. Configure Speed Test Settings 

  • Open your CLI and enter the following commands to configure the speed test settings: 
config system speed-test-setting 
   set latency-threshold 60 
   set multiple-tcp-stream 4 
end 
 

2. Ping the Closest Test Server 

  • Before running the speed test, ping the closest test server to ensure connectivity: 
execute ping <server_ip> 
 

3. Run the Speed Test 

  • Execute the speed test command to measure your internet speed: 
execute speed-test 
 
  • The results will display transfer rates and latency, giving you a comprehensive view of your network performance. 

Conclusion 

Regularly testing your internet speed with FortiGate helps maintain optimal network performance and troubleshoot any connectivity issues. Whether you prefer the GUI or CLI method, FortiGate provides the tools you need for accurate speed testing.
