For this topology, the managed device accesses the Mobile Device Manager (MDM) Gateway Server in the perimeter network to use MDM. The MDM Gateway depicted in this scenario may be used for both cellular and Wi-Fi communication for a managed device.
|It is assumed that MDM is deployed and operational in your network before proceeding with the setup guidelines offered in this section. For information on how to enable and configure Wi-Fi on your Windows Mobile device, see Windows Mobile Device Wi-Fi Configuration.|
Topology benefits include the following:
- An architecture that requires a minimal amount of configuration
and modification to your current MDM deployment.
- The ability to share infrastructure that supports both internal
and external managed devices.
The numbers in the above illustration highlight the following:
- The MDM managed device uses an internal wireless access point
to access the MDM Gateway Server external network interface in the
perimeter network. VPN client is enabled on the managed device.
- MDM Gateway Server passes network traffic from the managed
device to MDM Device Management Server. This process is similar to
a device communicating externally from your network to MDM Gateway
Server. If you are using a web proxy in the perimeter network to
route mobile device traffic back out to the Internet, no
modifications are required. Also, another possibility is for you to
use a tunnel default gateway, which routes all mobile device
traffic to the Internet.
- If the internal firewall does not allow IPsec traffic to pass
through bi-directionally, you must open UDP ports 500 and 4500 on
the internal firewall inbound and outbound. You must open Protocol
50 (IPsec ESP), if using non-NAT–based traffic.
