Here is what I don't get about that:
1) NFS4 doesn't rely on portmap anymore (according to RH documentation), so I assumed that 2049 was all I needed to worry about, however, unblocking that port doesn't do the trick.
2) How do you tell which version of NFS you are running? I am on 5.3. rpm -qi nfs-utils yields no results.
