OK......

I wrote out what I would have done maybe you can run through it and
double check things?

Make sure relevant nfs services are enabled....

** On server....

systemctl is-enabled nfs-lock.service
systemctl is-enabled nfs-server.service
systemctl is-enabled nfs-idmap.service

Also, make sure Port 2049 is open on the firewall

** On client

systemctl is-enabled nfs-idmap.service
systemctl is-enabled nfs-lock.service

Then go on to configure the shares....

** Server....

mkdir -m 1777 /nfs4exports
cd /nfs4exports
mkdir -m 1777 home
mount --bind /home home

To make the bind effective a boot time edit /etc/fstab to contain

/home               /nfs4exports/home   none    rw,bind 0 0

vi /etc/idmapd.conf      (Modify "Domain" line, making sure to remove
leading #)

vi /etc/exports    (Added 2 lines)

/nfs4exports       
192.168.0.0/24(ro,sync,insecure,root_squash,no_subtree_check,fsid=0)
/nfs4exports/home  
192.168.0.0/24(rw,nohide,sync,insecure,root_squash,no_subtree_check)

exportfs -rv


** Client....

mkdir /mtranch-home

Then just mount....

Note....I just copied my information....so the IP addresses may not be
correct.
