You didn't select any level of "firewalling" when you installed RH7.2, did
you. If you select anything other that "none", then NFS will not work on your
machine. If this is the case, disable IPCHAINS or IPTABLES (or both), in
your start up directory, using, for example, ntsysv. Make sure that your
machines have other protection from the nasties on the Internet before you
do this!
