When using the standard router supplied by A1, there is no ability to dictate the DHCP settings required to successfully bind the mobile computer to the server. This however, is a requirement in order to synchronize the home folder of the mobile computer with the home folder of the Open Directory user account.
The DHCP settings required by the mediaBox used by A1 for sending IPTV content to the television prevents using the server with an arbitrary domain. Rather, A1 dictates a local domain of .home be used for all their devices.
