Outbound connections: BlackBerry UEM to the BlackBerry Infrastructure
    BlackBerry UEM
 to the BlackBerry Infrastructure
BlackBerry UEM
 must connect with and receive data from the BlackBerry Infrastructure
 to perform tasks. BlackBerry UEM
 connects with the BlackBerry Infrastructure
 over the outbound-initiated, two-way port 3101 (TCP).Your organization's firewall must allow outbound two-way connections over port 3101 to 
<region>
.srp.blackberry.com, <region>
.bbsecure.com, and <region>
.turnb.bbsecure.com. If you install the device connectivity components (the 
BlackBerry Connectivity Node
) on a separate computer, your organization's firewall must allow connections from that computer over port 443 through the BlackBerry Infrastructure
 (<region>
.bbsecure.com) to activate the BlackBerry Connectivity Node
. All other outbound connections from the BlackBerry Connectivity Node
 use port 3101 through the BlackBerry Infrastructure
 (<region>
.bbsecure.com). To add a BlackBerry Connectivity Node
 instance to an existing server group when you activate it, your organization's firewall must allow connections from that server over port 443 through the BlackBerry Infrastructure
 (<region>
.bbsecure.com) and to the same bbsecure.com region as the Core server. You have the option of routing data from 
BlackBerry UEM
 through your organization's TCP proxy server to the BlackBerry Infrastructure
. If you choose to send data through a proxy server, configure the firewall to allow the following outbound two-way connections:
        - Use port 3102 as the default listening port to connect theBlackBerry UEMcomponents to the TCP proxy server
- Use port 3101 as the default listening port to connect the components that manageBlackBerryOS devices to the TCP proxy server
If you configure 
BlackBerry UEM
 to use a TCP proxy server, verify that the proxy allows connections over port 3101 to <region>
.srp.blackberry.com, <region>
.bbsecure.com, and <region>
.turnb.bbsecure.com.
Activities initiated by the 
BlackBerry UEM Core
 over the port 3101 connection to the BlackBerry Infrastructure
| Purpose | Description | 
|---|---|
| Authenticate  BlackBerry UEM | Connect to the authentication service to authenticate the  BlackBerry UEMinstallation and allow the components to use the BlackBerry Infrastructureservices. | 
| Enable licenses | Connect to the licensing infrastructure to activate your organization’s server licenses and to enable  BlackBerry 10, iOS, Android, and Windowsdevices to use SIM licenses obtained from your service provider. | 
| Request a signed CSR | Connect to the signing infrastructure so you can request a certificate signing request (CSR) from  BlackBerry. You use the signed CSR to obtain and register an ApplePush Notification Service (APNs) certificate, which you require to manage iOSdevices. | 
| Activate and manage  BlackBerry 10devices | Connect to the  BlackBerry Infrastructureto: 
 | 
| Communicate with notification services | Connect to the  BlackBerry Infrastructureto send data to the appropriate notification service for supported device types (APNs, FCM, or WNS). | 
| Communicate with the  BlackBerrypush data service | Connect to the  BlackBerrypush data service so that you can manage and configure settings for BlackBerry 10devices. | 
| Discover server connection during activation | Connect to the discovery service so that  BlackBerry UEMcan find and use the server connection automatically when users activate devices. If you turn off this connection, users must specify the server manually when they activate devices. | 
| Update device OS data | Connect to the  BlackBerry Infrastructureevery 24 hours to check a hosted metadata file for new device or OS data. Updates are downloaded to the BlackBerry UEMdatabase. | 
| Search for apps | Connect to the  BlackBerry Infrastructureand then to the App Storeor BlackBerry Worldso that you can search for apps to add to the available app list. | 
| Purchase and push apps to  iOSdevices | Connect to the  BlackBerry Infrastructureand then to the App Storeto allow you to buy and push apps to iOSdevices. | 
Activities initiated by 
BlackBerry Secure Connect Plus
 over the port 3101 connection to the BlackBerry Infrastructure
| Purpose | Description | 
|---|---|
| Secure connection from work apps to work resources | Connect to the  BlackBerry Infrastructureto provide BlackBerry 10, Android Enterprise, and Knox Workspacedevices with a secure connection to work resources using BlackBerry Secure Connect Plus. | 
Activities initiated by the components of the 
BlackBerry Connectivity Node
 over the port 3101 connection to the BlackBerry Infrastructure
| Purpose | Description | 
|---|---|
| Establish secure device connections to work resources | You can install one or more instances of the  BlackBerry Connectivity Nodeto add additional instances of the device connectivity components to your organization’s domain. Each BlackBerry Connectivity Nodecontains the following BlackBerry UEMcomponents: 
 The  BlackBerry Connectivity Nodealso includes the BlackBerry Proxy, which maintains the secure connection between your organization and the BlackBerry Dynamics NOC. The BlackBerry Proxydoes not use the 3101 connection. |
