Remove the maintainer account (which allowed users to log in through the console after a hard reboot). Users who lose their password must have physical access to the FortiGate and perform a TFTP restore of the firmware in order to regain access to the FortiGate.
Hello everyone , in this video I am going to integrate fortigate firewall with radius server , after that fortigate administrators can login and manage fortigate by using their active directory username and password.
Step 1: Log into FortiGate
Access your FortiGate device through a web browser or SSH client.
Step 2: Navigate to System Settings
Go to System > Settings in the FortiGate web interface.
Step 3: Configure RADIUS Server
Under Authentication Settings, click Create New to add a RADIUS server.
Fill in the following details:
Name: A descriptive name for the RADIUS server.
Server: Enter the IP address or hostname of your RADIUS server.
Secret: This is a shared secret key that must match the one configured on the RADIUS server for authentication. It ensures secure communication between FortiGate and the RADIUS server.
Authentication Port: Usually set to 1812 for RADIUS authentication.
Accounting Port: Typically set to 1813 for RADIUS accounting, if needed.
Click OK to save the RADIUS server configuration.
Step 4: Define a RADIUS Server Group
Under Authentication Settings, click Create New to add a RADIUS server group.
Give the group a descriptive name to identify it later.
Add the previously configured RADIUS server(s) to the group. You can use multiple RADIUS servers for redundancy and load balancing.
Select the RADIUS servers from the list and use the right arrow button to move them to the “Selected” column.
Click OK to save the RADIUS server group.
Step 5: Configure User Groups for RADIUS Authentication
If you want to use RADIUS for user authentication, navigate to User & Device > User Groups.
Edit an existing user group or create a new one based on your needs.
In the user group settings, go to the Remote Groups section and select the RADIUS server group you created in Step 4.
This configuration ensures that users in this group will be authenticated against the RADIUS server.
Step 6: Testing
It’s essential to test your RADIUS configuration to verify that it’s functioning correctly. You can do this by attempting to log in using user accounts associated with the RADIUS server.
Step 7: Monitoring and Troubleshooting
FortiGate provides various monitoring tools under Log & Report where you can review RADIUS authentication and accounting logs. These logs can be instrumental in troubleshooting any issues with the RADIUS configuration.
Step 8: Additional Configuration
Depending on your specific requirements, you may need to configure additional options such as RADIUS accounting, timeout settings, and other advanced features. Consult the FortiGate documentation for comprehensive details on these options.
Step 9: Save Configuration
Make sure to save your configuration changes to ensure they are preserved across device reboots and updates.
By following these detailed steps, you can set up FortiGate to authenticate and authorize users through a RADIUS server effectively. This configuration enhances network security by centralizing user authentication and access control.
