Problem mounting NFS in a Merlin AC68U

[oversim]

Hi,
I have a DS213j, and I would like to mount a nas mountpoint in the AC68U using NFS.
I read tutorial (eg https://www.synology.com/en-us/knowledgebase/tutorials/616) but when I run the "mount" command in the Asus, I get a "failed: Connection refused".

Is there a "special" option? I did assigned NFS Permissions to the Shared Folders as the tutorial, but it does not work...

Thanks!

My fault.
Do not know why, but with -o nolock option it works...
