I can mount fine. The problem is that various programs (LyX, LibreOffice) freeze when attempting to open files on those filesystems.

Which it does, since disabling the firewall on the server solves the problem. (There's no firewall on the client.)
OK, sorry, I was only thinking about the initial post.
I tested and found some problems opening a file with LibreOffice in "edit" mode when using NFS-v3.
It would only open "read only". Get a message from lockd that user is "unknown". Too early in my
AM to track this down. It maybe related to idmapd. Will see if I can find the cause later today.
Thanks for the help. It's much appreciated.
Just to clarify: Stopping the firewall solves my problem.
One more piece: I tried using rpcdebug to see if there were any
error messages on the server. Nothing, at least with 'rpcdebug -m
nfsd -s auth -s lockd -s fileop'. I also tried 'rpcdebug -m nlm -s
all'. Again nothing.
On the client, I tried 'rpcdebug -m nlm -s all'. That produced:

It seems like it must be a firewall issue. But nothing has
changed on the server (except my enabling more things on the
firewall since all this started).
