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 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 
BlackBerry Router
 or 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, a TCP proxy server deployed in a DMZ, and the 
BlackBerry Router
 deployed in a DMZ.
