NFS Write Enabled Local Host - Ignored!

[pdharg1]

On my several years old Readynas Duo. I have the following set up:

Share list - media - nfs options
Default access: read only
Write enabled hosts: dv-460mt.local

I can access media from dv-460mt but can only read the files and cannot write.

To confirm that my duo knows what address dv-460mt is on, I have logged on to my duo over ssh and can successfully ping dv-460mt.

Ideas please as to what I might be doing wrong or what I might try next? Thank you.

On some of these fields, only IP addresses will work. If you try it by IP, does it work properly?

[pdharg1]

I assume it would but I have dynamic addresses.
Do you know why hostname does not work, maybe I can fix it?

Can you reserve the addresses in the router? Then you'd have the benefits of DHCP, combined with the ability to have predictable IP addresses.
