To echo the above, if you have a firewall in place on your FE, just turn
it off as you probably don't need it anyhow.

You say that the NFS partitions are always mounted?  I take it, then,
you are not using automounter (autofs) or anything along those lines,
which would mean that you have the entries in your local /etc/fstab
file.  If that is the case, what are the options you have listed for the
mount point?  How about on the main server.. what do you have in your
/etc/exports?
