Don't use a firewall for Cluster traffic. It just slows things down with
added latency (really not what you want).

We (ndb) gets the operating system to assign free ports to work on - so
it's not predictable.

The protocols that MySQL Cluster uses between the nodes are NOT secure
and if you swamp that network with other traffic, performance will
suffer (including the possibility of missing heartbeats). i.e. a whole
world of bad.

Run the cluster traffic on its own private network with no firewalls
getting in the way. easiest and fastest way.
