Configuring the

BlackBerry Connectivity Node

to use the

BlackBerry Router

or a TCP proxy server

To use a proxy server with the

BlackBerry Connectivity Node

, you can install the

BlackBerry Router

to act as a proxy server, or you can use a TCP proxy server that is already installed in your organization's environment.

You can install the

BlackBerry Router

or a proxy server outside your organization’s firewall in a DMZ. Installing the

BlackBerry Router

or a TCP proxy server in a DMZ provides an extra level of security. Only the

BlackBerry Router

or the proxy server connects to the

BlackBerry Connectivity Node

from outside the firewall. All connections to the

BlackBerry Infrastructure

between the

BlackBerry Connectivity Node

and devices go through the proxy server.

By default, the

BlackBerry Connectivity Node

connects directly to the

BlackBerry Infrastructure

using port 3101. However, if your organization's security policy requires that internal systems cannot connect directly to the Internet, you can install the

BlackBerry Router

or a TCP proxy server. The

BlackBerry Router

or TCP proxy server acts as an intermediary between the

BlackBerry Connectivity Node

and the

BlackBerry Infrastructure

.

This image shows the following options for sending data through a proxy server to the

BlackBerry Infrastructure

: no proxy server, and a TCP proxy server deployed in a DMZ, and the

BlackBerry Router

deployed in a DMZ.
