I am not sure if the -public switch is equal to allow all ranges as I before only have seen Hanewin users haveing the -range option. Maybe someone wiith a Hanewin can confirm.
Well I personally would try it via autofs (even so fstab should be similar).

Basically your /etc/auto.nfs.shares should look like this
/mnt/UltraHD 192.168.0.2:/UltraHD
