Sorry for continuing this thread but it looks like I am running into the exact problem.
Unfortunately for me, the solution from
@[deleted] of changing IP = * just gives me a nfs mount time out error.
@[deleted], I did RTFM, but I am afraid it did not help me in this case

I also can SSH into runeaudio or NAS.
I tried to manually mount NAS dir from rune (root ssh), but there was no response.
Any further thoughts/ideas? (I have limited linux/networking/mount experience)
Thanks, John
