That's NFSv4, which is certainly much easier to firewall (that was part of their design decision). Prior version of NFS required use of the portmapper, which is what makes all of this complicated. I know that at my work, our central NAS appliance simply didn't have the feature of specifying static ports for NFSv3 portmapper interactions. So we had to allow based on IP addresses.
