</div>The EPMD port is necessary but not sufficient. From the details provided<br>
in your previous email you would have needed to open port 57641 also.<br>
This is a random port. Do you see packets on this port in your network<br>
trace?<br>
<br>
I would suggest temporarily eliminating the firewall entirely for<br>
debugging purposes. See the firewall section on the clustering page for<br>
configuration details:<br>
