Minimum ports to open between 

BlackBerry UEM

 instances

The active 

BlackBerry Affinity Manager

 must be able to connect to and poll the health of each instance of the 

BlackBerry Dispatcher

 in the domain. For this purpose, ports 139 and 445 must be open between each 

BlackBerry UEM

 instance.

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).

If you are migrating data from one 

BlackBerry UEM

 instance to another, the ports that must be open between the source and destination servers are 8887 (TCP) and 35844 (TCP) for 

BlackBerry UEM

 and static ports 1433 (TCP) and 1434 (UDP) for 

Microsoft SQL Server

.

The following listening ports must be open between each instance. The default port values are listed. After you install the first instance, you can verify the listening port values that the setup application defined. For instructions, see Check the ports assigned by the BlackBerry UEM setup application.
