Ok, thank you very much, I just wanted to be sure that I wasn't
overlooking something.

Basically they don't. In a CMAN cluster there is a join protocol that
all nodes
have to go through to become a member and cluster nodes will only talk
to known
members.

But as things currently stand if someone spoofs the IP address, port &
cluster
number then it will get through I'm afraid. The solution is to use a
private
network for cluster communications.
