MBL Safepoint via WD N750 on WD external Mybook

I own a MyBookLive NAS, a WD N750 MyNet and a WDMybook.

I am looking for a method to use the Mybook, attached to the N750 from the MBL to store safepoints.

My laptoop sees the n750 and the Mybook as network storage, the MBL can’t detect it ???

Be sure the Workgroup setting in the MBL is the same as your local network.
