Ok, after some problems with the vmdk file and other things, I finally importet the VM sucessfully.
But I don't get any network. When I import the VM on VirtualBox everything works.
Do I don't get an IP because of the VMWareTools? How can I install this when DSM not installed already?
This are my settings in the VM: --> I changed the Mac-Address for the Jun’s Mod V1.03b loader
