cnMaestro 4.0.1 (Cloud) Release Notes


This document highlights new features and significant updates in cnMaestro Cloud.

Important: Web Browser
Restart your browser (or clear the browser cache with a hard reload) if you are having UI problems with the 4.0.1 update.

Assists for Enterprise Wi-Fi APs X

Assists are now supported on enterprise Wi-Fi APs. This feature scans device configuration and generates an Assists Score, which is displayed as a percentage of successful evaluations. Assists summary scores are available for System, Network, Site, Tower, and Device levels in the hierarchy.

Assists Dashboard

The Assists Dashboard presents the Assists Score and the list of evaluated Assists.


Affected Devices

Devices failing evaluation are displayed in a table.


Enterprise Wi-Fi Dashboard with Assists Score

The Assists widget has been added to the Enterprise Wi-Fi Dashboard page.


Guest Access Enhancements

The Guest Access Portal > Splash tab is renamed Design to accommodate the new changes.


The Guest Access Portal > Sessions tab is split into the following 3 tabs:

  • Sessions and Login Events
  • Paid Transactions
  • Users


Microsoft Azure-based Authentication X

The Guest Access feature now supports Microsoft Azure-based authentication, which allows users to authenticate to the Wi-Fi network using Single Sign-On through their Azure Active Directory credentials. This feature simplifies the login process for users with an Azure account and eliminates the need for separate login credentials.


Sponsored Guest Authentication X

Sponsored Guest Authentication allows guests to access the network by entering a sponsor’s email address. This limits the administrative overhead of managing guest networks, because it distributes the approval process while ensuring only authorized guests can access the network.


Administrators can design Sponsor and Guest email templates using the Design > Email Template page.



cnWave 5G Fixed Configuration Update and Tools Support

Template-based configuration is added for both cnWave 5G Fixed BTS and CPE devices. A template can be added from Configuration > Templates > Add Template.



The “Tools” tab is added to download Tech Dump files and reboot the cnWave 5G Fixed BTS and CPE devices.



NSE 3000 Features

Application Control on Source IP/Subnet

Support for source subnet-based Layer 7 Filtering is available. Earlier, Layer 7 rules were applied to all VLANs present on the device. With this feature, users can apply the Layer 7 filter only to traffic originating from a specific source subnet.

To enable this feature, create an Application Filter Rule which maps to the application name, category, or both.



Once created, the user can configure a User Group. Users define the source subnet or select all local subnets within the User Group and attach the Application Rule.



IPsec IKEv2 EAP Client

for IKEv2 remote VPN tunnels is now available (in addition to L2TP over IPsec remote VPN tunnels).

To configure this feature:

  • Enable the VPN server by clicking the "Enable inbuilt VPN server".
  • Enable the RADIUS server by clicking the "Enable inbuilt RADIUS Server" option.
  • Configure the DHCP pool the remote VPN client will receive upon successful authentication.


The remote IKE VPN client is authenticated using signed certificate. This certificate must be obtained from a trusted Certificate Provider such as GoDaddy, Comodo, or Let’s Encrypt and pushed to the device from cnMaestro.

NOTE: cnMaestro only supports uploading certificates in PEM or DER format.


After a successful certificate push, the status should display as “IN SYNC”.


Port Range Support for Port Forwarding Rules

Starting with release 1.3, NSE 3000 allows the configuration of a port range in port forwarding. For example, a single rule can map the public port range 2000-3000 to the LAN port range 2000-3000. This is required for VoIP deployments.


60 GHz cnWave Enhancements

Support CB2 channels on Map

New channels 9,10, and 11 are available for 60 GHz cnWave V3000 device when Channel and Polarity mode is selected in the Device Overlay section.


Disable Downlink Multicast Flood for PoP Device

Disable Downlink Multicast Flood option is available under PoP Device > Configuration > Network > Layer 2 Bridge.


Onboard E2E To External E2E Migration with Sites and Devices

Previously, Onboard E2E to External E2E migration could only be done if the External E2E controller had no Sites or Devices. This release lets users migrate Onboard E2E to External E2E when Sites and Devices are present.

Bulk Acknowledgement of Alarms

Acknowledge multiple alarms using the Bulk Acknowledge option.


Miscellaneous UI Changes

Configuration Lock Feature is moved from Administration > Settings to Configuration > Advanced Features page.


Tagging cnMatrix X Features

The cnMaestro UI clearly demarcates the following X features for cnMatrix devices:

  • Auto Device Recovery (ADR)
  • Cable diagnostics
  • MAC lists for PBA
  • Location services for PBA

Mesh Peers is Removed from Data Reports

The Mesh Peers tab is removed from Data Reports because it is not supported in Cloud.

Have yet to do it in the lab but with Sponsor Guest Settings can you lock it down to a bunch of specific email addresses that are allowed to sponsor ie and ?

Really don’t want any person to be able to approve Guest access as its open to total abuse as we’ve seen over the years.
