You will need to constrain the inet_dist_listen_min and
inet_dist_listen_max kernel app settings. More details can be found here:

For an example of a configuration file that specifies a distribution
port range see

It is possible to specify this using the RABBITMQ_SERVER_ERL_ARGS
environment variable, but I would recommend using the config file instead.
