FortiGate / FortiWiFi

Compatibility

Social WiFi has been tested and is proven to work on the following configurations:

FortiWiFi – wireless interfaces

• FortiOS version 5.6.0 and above (tested up to 7.6.3)

FortiGate hardware or virtual machine – wired interfaces

• recommended: FortiOS version 6.2.4 and above (tested up to 7.6.3)
• FortiOS version 5.6.0 and above work if the captive portal is enabled on a physical interface, VLAN interfaces are not supported below FortiOS 6.2.4

Access the device’s configuration panel

This guide assumes using the web based UI of the controller, which you can access by entering the IP address of the device in your browser. The screenshots are based on firmware v5.6.2.

Alternatively, if your device is managed from FortiCloud, you can access the management UI from there.

RADIUS configuration

Go to User & Authentication → RADIUS Servers → Create New and use the following settings:

Name	Social WiFi
Authentication Method	Specify
Method	PAP
NAS IP	Leave empty
Include in every user group	Unchecked
Primary Server IP/Name	35.205.62.147
Primary Server Secret	Radius Secret is available in Access Points tab of the Social WiFi Panel
Secondary Server IP/Name	Leave empty
Secondary Server Secret	Leave empty

Click OK.

Tip

Test Connectivity button is not supported, so don’t worry if you see an error like ‘Invalid secret for the server’.

You can test the connectivity with our RADIUS server by using the Test User Credentials button.

For username and password use the value test_YOURRADIUSSECRET - replace YOURRADIUSSECRET with the Radius Secret available in Access Points tab of the Social WiFi Panel. For example, if your Radius Secret is 123456, the username and password would be test_123456.

Now you need to change the RADIUS port to 31812. Open the CLI Console (top right corner, between “help” and username).

You will see the terminal pop up. Please copy (ctrl+C) and paste (ctrl+V) or type in the following commands:

config user radius
    edit "Social WiFi"
        set radius-port 31812
    next
end

Click enter, then copy and paste the below.

config user radius
  edit "Social WiFi"
    config accounting-server
      edit 1
        set status enable
        set server 35.205.62.147
        set secret [*your radius secret from the panel*]
        set port 31813
      next
    end
  end

Then close the CLI console by clicking the “x” button in the top right corner.

Remote Group configuration

Go to User & Authentication → User Groups → Create New

and use the following settings:

Name	Social WiFi - Guest
Type	Firewall
Members	Leave empty

Under Remote Groups, click +Add.

Select Social WiFi from the Remote Server dropdown list. Make sure that Grups are set to Any. Click OK to proceed.

Click OK.

Setting the auth-timeout

Open up the console again and enter the following commands:

config user setting
set auth-timeout-type idle-timeout
end
config user group
edit Social\ WiFi\ -\ Guest
set authtimeout 480
end

Where the “set authtimeout 480” is in minutes and you can adjust the value freely. This will make your users have to relogin after not being active in the network for 8 hours.

Walled Garden configuration

Now we need to add all the services that will be available without logging in. This list includes Social WiFi login page and third-party social login services (like Facebook).

The following guide assumes firmware version 5.6.2, which doesn’t support domains with wildcard (e.g. “*.facebook.com”). Using wildcards was added in firmware 6.2.2, so if you have that version or higher, you may adjust the following steps accordingly.

The suggested way to add all required entries, is to use the console again to copy (ctrl+C) and paste (ctrl+V) the following scripts.

Tip

Please note that the script is split into two parts. There’s a length limit on FortiGate that cannot be exceeded.

Interface or WiFi interface configuration

Note

Social WiFi can be installed either on an interface (physical or VLAN) or on SSID, if FortiAPs are used. Please pick the correct variant below.

Interface configuration (wired interface)

Go to Network → Interfaces and edit the interface you want Social WiFi to work on. The below example uses a VLAN, but this works on a Physical interface as well.

Configure the “Network” section of the interface as follows:

Security Mode	Enabled: Captive Portal
Authentication Portal	External: http://login.socialwifi.com/
User Access	Restricted to Groups
User Groups	Social WiFi – Guest
Exempt Sources	Leave empty
Exempt Destinations/Services	Social WiFi
Redirect after Captive Portal	Original Request

Click OK.

WiFi configuration (wireless interface)

Go to WiFi Controller → SSIDs and edit your Guest SSID.

Configure as follows:

SSID	Social WiFi (or any name that you prefer)
Security Mode	Open (Recommended, only available after enabling Captive Portal)
Captive Portal	Captive Portal
Portal Type	Authentication
Authentication Portal	External: http://login.socialwifi.com/
User Groups	Social WiFi – Guest
Exempt Sources	Leave empty
Exempt Destinations/Services	Social WiFi
Redirect after Captive Portal	Original request

Click OK.

Firewall configuration

You need to allow for traffic from guests using Social WiFi, because the default policy is to deny all traffic.

Go to Policy & Objects → Firewall Policy → +Create New.

Configure as follows:

Name	Social WiFi Allow Guests
Incoming Interface	The interface that has Social WiFi configured
Outgoing Interface	Your WAN interface
Source	all
User/group	Empty
Destination	all
Service	ALL
Action	ACCEPT

Click OK.

Add the device to Social WiFi Panel

The setup of FortiGate is now finished. The last step is to add the MAC address(es) to the Social WiFi platform.

If you configured Social WiFi on an interface, you only must add the one interface used.

If you configured Social WiFi on an SSID, you must add all the MAC addresses of the Access Points. Usually the MAC address will be printed on a label on the device itself. It should be visible in the GUI as well on the edit interface screen. If you don’t know the MAC address, please contact Social WiFi Support.

Now, switch to Social WiFi Panel, go to Access Points tab, click the Add button and paste the MAC address(es). Click Create.

Test the solution

Connect with the WiFi network. You should see a login page. Go through the login process and, once finished, you should have internet access. You should see first connections and authorisations in the Social WiFi Panel’s statistics section.

Troubleshooting

If you have any external firewall behind the FortiGate device, please make sure that you enable these ports:

• TCP/8080 (Captive Portal (http redirection))
• TCP/8081 (Captive Portal (https redirection)
• UDP/9177, 337008 (AP Communication (Capture Packets subsystem))
