Hi Boby,
Could you please confirm the Nas gateway & Aclass 3800fD connected to MAC osx or Linux operating system?
Notes on Current Network Protocol Support for Supported Operating Systems
• Current testing and support for Mac OS X and Microsoft Windows is for the SMB/CIFS network protocols.
• Current testing and support for Linux is with the NFS network protocol.
A. To mount the share with NFS on OS X, it must be mounted via command-line since the 'Connect to Server or ⌘ + K' will fail.
If you want to use NFS, follow the below syntax:
sudo mount -t nfs -o rsize=1048576,wsize=1048576,nolock,locallocks X.XXX.XX.X:/nasmnt/fs1 /private/fs1
Make this auto-mount this with an automaster and autonfs file on OS X.
It is preferable that SMB and not NFS on OS X.
Our official supported protocol on OS X is SMB.
Regards
Hari
