Dear All,
I have my cluster setup and passing all tests on the test connectivity in admin except I get a warning when the test does PingServerSocketHost Test WARNING
Host *HostName* does not respond to java.net.InetAddress.isReachable().
If I turn off the firewall all is good, but I have been searching and testing for days and can't find what I need to allow through the firewall to stop getting these warnings. Please any advice would be helpful.

Sorry I should mention the cluster is all built on Windows 64 bit and Matlab 2013a. It is on a domain and all the machines can ping each other with long and short names.
