That can work fine. Just make sure that your cluster interfaces can access tcp ports 22, 80, 3001, 3002 and udp tftp, dns, dhcp, and udp ports 1900 and 3001 at minimum. You may have more services you want to open but I think that's a good minimal list at the moment off the top of my head.

I'm looking for some way to curtail the security auditors from continuously probing our cluster and sending reports. John McCulloch | PCPC Direct, Ltd. | desk 713-344-0923
