Step 6: Add miniOrange as RADIUS Server in FortiGate

Secondary Server IP / Name:	Optional
Secondary Server Secret	Optional

• To Save these settings click OK.

Step 7: Test Connectivity

• You can now verify the connectivity by clicking on Test Connectivity.

Step 8: Create a User Group in Fortinet

• NOTE: If you have a existing User Group then just add miniOrange Radius Server as the Remote Server. If not, then follow the below steps.

• So connect to the appliance CLI.
• And execute below commands in command line: #config system global #set remoteauthtimeout 30 #end

Step 11: Test miniOrange 2FA setup for Fortinet VPN Login

• Login to Fortinet and enter Username and Password.



• It will prompt for a Second Factor Code if you have Enabled 2-Factor Authentication in miniOrange Policy.



• Enter your 2-Factor Code and you should be connected to the VPN.
• NOTE: While configuring IPSec VPN connection in FortiClient make sure to use the Pre-Shared key of the IPSec Tunnel that was created LAST. Fortinet has issues if multiple IPSec Tunnels are present at FortiGate Server
• On passing the valid credentials you can see the screen below:



• If you enter an incorrect value you will be redirected to the below screen.
