[rabbitmq-discuss] Unable to cluster rabbit nodes

[Anders Ljusberg]

You may have already figured this out by now, but for anyone else.

Rabbit by default uses a random port range to do the actual communication 
between nodes in the cluster and you need to allow communication on all 
these ports. If it's the Windows firewall that is blocking you, the easiest 
way is probably to allow erl.exe to communicate on any TCP port.

See the last paragraph under "(Windows) Firewall Settings" in my post on 
clustering RabbitMQ on Windows:
