Question

Why can’t users mount the NFS share folder on a Mac OS X device through "Go > Connect to Server"?

Answer

By default, a Mac OS X connects to an NFS server from a "non-privileged" TCP/IP port which is ≥ 1024. Since the ZyXEL NAS/NSA only accepts the authentication port from a "privileged" TCP/IP port, ≤ 1023, when mounting the NFS share folder with the ZyXEL NAS/NSA on a Mac OS X device, the user has to add the parameter "resvport" to cause Mac OS X to use a privileged port.

In the OS X GUI, "Go > Connect to Server" can't add/select the parameter "resvport”. Therefore even when typing the full path as “nfs://NAS_IP/i-data/volume/nfs/NFS_folder” in order to connect, the connection still fails.

Try to mount the NFS folder as follows, with the “-o resvport” command in the terminal:
$ sudo mount -t nfs -o resvport NSA_IP:/i-data/volume/nfs/NFS_folder
