The BlackBerry® Router connects to the wireless network and sends data to and receives data from the BlackBerry® Infrastructure on behalf of the BlackBerry® Enterprise Server. The BlackBerry Router also sends data to and receives data from BlackBerry devices that are connected to the BlackBerry® Device Manager or a Wi-Fi® network. The BlackBerry Device Manager is included with the BlackBerry® Device Software, BlackBerry® Web Desktop Manager, and BlackBerry Administration Service.
When the BlackBerry Enterprise Server detects a BlackBerry Router, it identifies the IP address of the computer that hosts the BlackBerry Router and writes the IP address to the BlackBerry Configuration Database. When BlackBerry device users activate devices that are running BlackBerry Device Software 4.0 or later, the BlackBerry Router sends the IP address to the devices in a service book.
If you change the IP address of the computer that hosts the BlackBerry Router, devices detect the change automatically. Users do not need to reconnect devices to the BlackBerry Device Manager to receive the new IP address and a new service book. However, a delay occurs before devices detect the change. During the delay, devices cannot connect to the BlackBerry Device Manager or a Wi-Fi network.
The BlackBerry Router supports the use of multiple network cards on users’ computers, which is also known as multihoming.
