I'll look this up at work on Monday. The default setting for NFS and
RPC-related stuff is to use random ports which makes it nearly
impossible to allow though a firewall. If you set the right parameters
you can tie down the used ports and easily write firewall rules. We
have RHEL4 (=CentOS4) systems at work, but I can't  remember the
parameters without a cheatsheet.
