In UEM on-premises environments, you can configure a transparent TCP proxy server for the BlackBerry UEM Core service. This service requires an outbound connection and may also have different ports configured. You cannot install or configure multiple transparent TCP proxy servers for each service.

In UEM Cloud environments, the BlackBerry Connectivity Node sends activation data over port 443 (TCP). After it is activated, the BlackBerry Connectivity Node sends and receives data over port 3101 (TCP). You can configure the BlackBerry Connectivity Node to route TCP data through a transparent proxy server that is behind your organization’s firewall. The BlackBerry Connectivity Node does not support authentication with a proxy server.

You can configure multiple TCP proxy servers configured with SOCKS v5 (no authentication) to connect to UEM. Multiple TCP proxy servers configured with SOCKS v5 (no authentication) can provide support if one of the active proxy server instances is not functioning correctly.

You configure only a single port that all SOCKS v5 service instances must listen on. If you are configuring more than one TCP proxy server with SOCKS v5, each server must share the proxy listening port.
