It doesn't hurt to start with a firewall:
In this case, 192.168.10-12 are imaginary cluster nodes. You probably want to leave off the rule for port 8443 on nodes that don't run the web console. Put your firewall commands in a script and run it from /etc/rc.local.
It's very important to control the hosts that can connect to the NFS filesystem, a firewall is just one way to do it. I don't know the correct way to limit specific hosts that can connect to the NFS server in the mapr config files.
