There are two possible answers to you question. CMA-D is the desktop client to the CMA server, it will only work by firstly registering with the CMA server. This is either directly if on the same network as the server or via a VBP-S device. Or you may be referring to the Real Presence Mobile for Windows, also known as m100, which does not need to register to anything and can enter your network via a VBP-E device.
