Duo suddenly does not allow NFS mounts
I have several ReadyNas Duos and have always had them set up to allow NFS mounting of the shares with root access. A few months ago, with no change to the system or clients, some clients can not moun...
I belive it did, but I can't be sure exactly when I started to see the problem.
It began after a raspberrypi I am running crashed. It had the share mounted and after it came back up, it could not mount the share anymore. I assumed that something was corrupted and reinstalled from scratch only to find that it did not resolve the issue. I chaged the IP address, hoping that would resolve it. I then realized that any machine that had not previously connected to nfs on the NAS, would not be able to mount the share. I have several systems that are currently conneted and can mount and unmount, but no new systems. My guess was that there was an issue with newer versoins of the nfs client, but the raspberryPi was installed with the exact same build after it crashed and it was able to mount prior to the crash.
It seems to me that there is some sort of iptable or filter or ACL that is forbidding the attempts to mount. The systems can ping and can see the http pages of the NAS, but simply can not NFS mount. I have removed all restrictions and rebooted several times.
