Barracuda CloudGen Firewall

How to Configure Wi-Fi AP Authentication

  • Last updated on

The Barracuda NextGen Firewall F-Series can parse authentication information contained in the syslog stream of supported wireless access points. Wi-Fi access points typically use authentication services such as RADIUS servers to authenticate users before allowing them to connect. The Barracuda NextGen Firewall F-Series monitors the syslog files sent by the Wi-Fi access points for the username and the associated IP address of logged-in users. Depending on the access point, the Barracuda NextGen Firewall F-Series receives login and/or logout information.

Supported Wi-Fi access points

  • Aerohive (login only)
  • Ruckus (login and logout)
  • Aruba (login only)
  • Aruba Instant (login only)

Watch the following video to see the Barracuda NextGen Firewall F-Series receive user information via Wi-Fi Access Point authentication from an Aerohive Access Point:

Before you Begin

Configure the Wi-Fi access point to stream the syslog to the Barracuda NextGen Firewall F-Series. For more information, see:

Step 1. Configure a Box Level IP Address

Add an IP address to the box level that can be reached by the wireless access point.

  1. Go to CONFIGURATION > Configuration Tree > Box > Network.
  2. Click Lock.
  3. Click + to add an Additional Local IP.
  4. Enter a Name.
  5. Select the interface from the Interface Name drop-down list.
  6. Enter the IP Address and Associated Netmask.
  7. Click OK.
  8. Click Send Changes and Activate.

Step 2. Configure Wi-Fi AP Authentication

If the Wi-Fi access point is using an SSL-encrypted connection, the certificate can be imported from a PEM or PKCS12 file. For non-standard Wi-Fi Access Point syslog streaming ports, change the port in Advanced View and edit the port in the BOX-AUTH-WIFI-SYNC rule accordingly.

  1. Go to CONFIGURATION > Configuration Tree > Box > Infrastructure Services > Authentication
  2. Click Lock.
  3. In the left menu, click Wi-Fi AP Authentication.
  4. Set Activate Scheme to yes.
  5. Click + to add a Wi-Fi AP Endpoint. The Wi-Fi AP Endpoints window opens.

    • TCP
    • SSL
  8. (SSL only) Enter the Certificate Subject Alternative Name for the SSL certificate.
  9. (SSL only) Click Ex/Import and import the Certificate File.
  10. Select the manufacturer of your Wi-Fi access point from the Wi-Fi AP Model drop-down list.
