Well, I normally do put a fixed IP on the NAS drives, since I access it a lot either to copy files or stream from it, this way it will always be on the same address.
everything is now fine and working
When I ordered my Cloud EX2, i thought that I could use to external disk that I already had… so I tried to set it up without any internal disks… and it did’nt work.
So I ordered (and received today) 2 internal red disks… and everything went fine… my DHCP IP address is a fixed one.
