What Is PPSK

 

A private Pre-Shared Key (PPSK for short) is a security solution in which individual client devices can be managed without much complexity. With PPSK, each user is assigned a unique passphrase for authentication. Also, it allows the binding of a passphrase and the device MAC address(es), and thus only the specified device can be authenticated using the passphrase. In PPSK, you can create the PPSK list and apply them to multiple wireless networks, saving you from repeatedly setting up the same information.

 

Omada SDN Controller supports two types of PPSK, PPSK without RADIUS and PPSK with RADIUS.

 

PPSK without RADIUS: Just create PPSK profiles on Omada SDN Controller.
PPSK with RADIUS:

  • EAP works as a Network Access Server (NAS). You need to create clients in the RADIUS server to allow the EAPs to submit authentication requests.
  • When the client connects to the SSID, EAP uses the MAC address of the client (in the format "xx:xx:xx:xx:xx") as the RADIUS User and User-password, the submitted PPSK as the Tunnel-password and submits the information to the RADIUS server for authentication. Therefore, you need to create users in the RADIUS server in the appropriate format.

 

 

How to Configure The PPSK Function

 

Kind Notes:

(1) When 6GHz is turned on, Security cannot be PPSK with/without RADIUS since 6GHz does not suppport them, please uncheck the 6GHz box so that you can configure the security with PPSK.

(2) If the EAP doesn't support PPSK without RADIUS, there will be an issue characterized by client devices being unable to detect the SSID on either frequency band, as the EAP will not broadcast SSID with PPSK without RADIUS configuration. So please make sure the current firmware version of your EAPs supports PPSK without RADIUS.

 

1. Configuration Guide for PPSK without RADIUS.

 

First, create a new PPSK profile by Settings --> Profiles --> PPSK, name the profile, and add PPSKs manually, automatically, or by import. Please refer to the User Guide for more information about the PPSK profile.

 

The following figure creates a PPSK. The name “TP-Link” is used to identify the PPSK, while the passphrase “tplink123” is used for authentication when clients connect to Wi-Fi.

 

If you enter the MAC address for a PPSK, then only specific clients can use the passphrase for authentication. If you define the VLAN assignment, then the client will connect to the corresponding VLAN after authentication.

After creating the PPSK profile, go to Settings --> Wireless Networks, create a new wireless network, and select PPSK without RADIUS and the PPSK profile.

2. Configuration Guide for PPSK with RADIUS.

 

Step 1. Set up the RADIUS server.

 

Here we are running a FreeRADIUS® server on a Linux server. For more information on installation and configuration, please refer to the FreeRADIUS documentation.

First, edit the “clients.conf” file. Here we assume that the EAPs are located in the network 192.168.0.0/24, and the shared secret used for communication between the EAPs and the RADIUS server is “tplink”, then the “clients.conf” file is configured like this:

Next, edit the “users” file. With the configuration shown below, three PPSK profiles are created.

 

4,20220519100558x

 

  • When the client with MAC address “xx:xx:xx:xx:xx:xx” submits PPSK “xxx_tplink”, it will be authenticated.

  • When the client with MAC address “yy:yy:yy:yy:yy:yy” submits PPSK “yyy_tplink”, it will be authenticated and connected to the network of VLAN 10.

  • When a client with an unknown MAC address submits the default password “default”, it will be authenticated and connected to the “Guest” network of VLAN 20.

 

 

Step 2. Create the RADIUS profile.

 

Go to Settings --> Authentication --> RADIUS Profile, and create a new profile bound to the RADIUS server. If necessary, note to check “Enable VLAN Assignment for Wireless Network”.

 

5,20220519100613f

 

 

Step 3. Create more interfaces for VLAN assignments (optional)

 

Go to Settings --- Wired Networks --- LAN, and create two interfaces with VLAN10 and VLAN20.

 

6,20220519100630k

 

 

Step 4. Create a wireless network encrypted with PPSK with RADIUS

 

Go to SettingsWireless Networks and create the new wireless network shown below.

  @Hank21 Hi Hank. It appears you cannot use PPPSK with Radius on the EAP's using the built-in Radius server on OC200 Controller? It does not appear in drop-down, and you are prompted to create a new radius profile. Is that correct?

Hi @Landfall2624

 

The built-in RADIUS server has been added from the Controller v5.12, which can be used for WPA-Enterprise, Portal RADIUS Server and 802.1X. So it is correct, please follow this article to create a new Radius profile.

  @Hank21 

 

Can PPSK mode be configured in standalone mode?  That is, using freeradius in some other server (such as pfsense).

 

Thank you

  @Hank21 why use the EAP as the NAS, but not the Controller? If there are hundreds of AP or even more, it's not reasonable to configure Radius Policy using EAP's IP.

Hi @TOHanks 

Do you mean the radius setting on your external server? Currently we can only use the EAP as the NAS. If you would like to use the built-in server in controller, please choose PPSK without RADIUS.

  @Hank21 

 

I'm considering buying an EAP683 UR (EU) but I'm using PPSK, does this ap support it?
I also wonder if the EAP625-Outdoor HD (EU) has PPSK

Hi  @MR.S 

 

I can confirm both of EAP683 UR (EU) and EAP625-Outdoor HD (EU) support PPSK. 

 

But they won't support the EKMS (Eleven Key Matching Service)

 Hi @Hank21,

 

I find this information very useful about setting up PPSK onto the TP-LINK Access Points but I'd like to know when this would be supported for EAP225 (V5) models. I have been struggling to get this to work until I found out that it wasn't supported yet, so I am having to revert to the old method of having multiple SSIDs which has multiple VLANs assigned to it... it just makes it look messy from the customer point of view when connecting to the WiFi.

 

If you could let me know when this would be supported for EAP225 (V5) models, that would be great.

 

Many thanks,

Ben

Regards, Ben
