I found these ports also bound to the public interface when I startup<br>
rabbitmq-multi. What are those ports used for and do they have to be<br>
bound to the public interface?<br>
<br>
I'd like to keep this as secure as possible.<br>

<br>Plain Erlang is meant to run in a protected environment. If you are concerned about connectivity to these ports, then there are ways of restricting/protecting the Erlang Node comms ports (see the kernel inet_dist_ sys.config entries <a href="http://www.erlang.org/doc/man/kernel_app.html">http://www.erlang.org/doc/man/kernel_app.html</a>, and SSL for Erlang distribution <a href="http://www.erlang.org/doc/apps/ssl/ssl_distribution.html">http://www.erlang.org/doc/apps/ssl/ssl_distribution.html</a>).<br>
