Hi John,<br>
<br>
I assume that you established the reason for the clustering problems<br>
encountered earlier was due to firewall configuration.<br>

<br>
</div>One port is possible (then inet_dist_listen_min = inet_dist_listen_max),<br>
but a small number like 5 is more common. Avoid the ephemeral port range<br>
when you make your selection.<br>

</div>As discussed previously and above, you need to open at least one port in<br>
addition to the one used by the port mapper daemon. You are free to add<br>
further firewall restrictions, as long as all clusternodes are<br>
accessible from all other clusternodes on the relevant ports, as<br>
discussed here:<br>
