Do you mean *only* those ports?

Erlang will by default open an arbitrary port for inter-node 
communication - to change this see:


For RabbitMQ use at least you can set min and max to the same value, eg:

{kernel, [{inet_dist_listen_min, 9100},
           {inet_dist_listen_max, 9100}]}

in your config file.
