[rabbitmq-discuss] How many ports does RabbitMQ need open?

Our systems are fairly thoroughly firewalled by default.
I want to cluster a couple of RabbitMQ nodes.
It's no problem to ask the sysadmins to open up some ports, and I have 
found how to adjust the kernel inet_dist_listen_* options to limit the 
ports Erlang will use..

But I wonder how many ports RabbitMQ really needs there?
Is one port enough? Ten? One hundred? One thousand?
