There's NO firewall between the clients and the DSS.
On the Web interface, in Configuration/Nas setting, "Use NFS" is checked, as well as on the shares. There's no IP restriction in place.
If I uncheck "Use NFS" and Apply : it takes 2 seconds. When I recheck the box and Apply, the web interface waits and waits and waits for a few minutes then stops (as if after a timeout) and the problem is still there : NO nfs.
The number of nfsd is set at the default: 64. The DSS has 18Gb of RAM.
The shares are accessible via samba and the content is perfectly normal. I attempted a Repair via the Extended Tools and rebooted, still nothing.
It looks like the nfs daemons and/or portmap fail to start, but I have no way to know why: nothing appears in the Event Viewer. No message, nothing.
I have some servers that need NFS access to this NAS.
