This is the notes from my setup.

I am setting up server for NFSv4 without Security IP based access list.
NOTE : Match your uid with anonuid

| /etc/exports

/home   192.168.1.0/24(rw,sync,insecure,root_squash,no_subtree_check,fsid=0)
/home/download      192.168.1.4(rw,nohide,sync,insecure,no_root_squash,no_subtree_check,anonuid=1000,anongid=100)
/home/movies    192.168.1.4(rw,nohide,sync,insecure,no_root_squash,no_subtree_check,anonuid=1000,anongid=100)
/home/net/Pictures  192.168.1.4(rw,nohide,sync,insecure,no_root_squash,no_subtree_check,anonuid=1000,anongid=100)

Now change following settings.
If any of the variable not exists please add as new line.
These disables legacy version and NFS v3 Support.
As keeping NFSv3 Support lead you to open many port in firewall and might cause issue on permission.

| /etc/sysconfig/nfs

MOUNTD_NFS_V1="no"
MOUNTD_NFS_V2="no"
RPCNFSDARGS="-N 2 -N 3 -U"

Add Following lines to your firewall rules.

| /etc/sysconfig/iptables

-A INPUT -s 192.168.1.4 -m state --state NEW -m tcp -p tcp --dport 2049 -j ACCEPT

Now restart / start all modified services.
In new Fedora it is some thing like as follow
Some server require to be started in specific order.

• systemctl restart rpcbind.service
• systemctl restart iptables.service
• systemctl restart nfs-idmap.service
• systemctl restart nfs-server.service

To setup client to mount exported FS use following.

| /etc/fstab

192.168.1.5:download /opt/download nfs4 proto=tcp,intr,rw 0 0
192.168.1.5:movies      /opt/movies nfs4 proto=tcp,intr,rw 0 0
192.168.1.5:net/Pictures /opt/Picture nfs4 proto=tcp,intr,rw 0 0
192.168.1.5:net/Music /opt/Music nfs4 proto=tcp,intr,rw 0 0

You can refer following manual for further information.
Since all these is some how i gathered from these documentation.
