I guess I should add that the only way I know that a firewall is not
running on either machine is a "/sbin/ipchains -L" on the server (since
it's RedHat 7.3), and a "/sbin/iptables -L" on the client (since it's
RedHat 9.0). All of chains have a default policy of ACCEPT with no rules.
Regardless, as I described above, each machine is successfully operating
in its desired role for _other_ NFS connections, just not the one I want
to establish.
