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.
I enabled firewall debugging and tried to open a LyX file on the nfs
share. I started seeing lots of these:

192.168.1.51 is the client; .2 is the server.
I then rebooted and tried a LibreOffice file:

I don't know if it matters, but I also see

pretty much as soon as I boot.
I will see if I can reconfigure the server to use NFS-v4.
