Mount NFS share on Fedora with Asustor. At first check official description here:

After you do the share on your Linux you can add to /etc/fstab:
192.168.1.66:/volume1/Z /media/Z nfs defaults 0 0
192.168.1.66:/volume2/X /media/X nfs defaults 0 0
Of course you can try mount manually:
$ mount -t nfs 192.168.1.66:/volume1/X /media/X
