Ah, you're thinking of when it is clients connecting to the MQ.
I'm talking about clustering multiple RabbitMQ nodes.

It definitely needs a few more - the erlang port mapper on 4369 for 
starters - and then some more that erlang dynamically chooses. (Although 
can be limited to a range with the parameters I mentioned below)

I'm curious to know how many are really needed for those extras; if I 
limit the range to just 5 ports, am I likely to hit troubles? How about 
100 ports?

Cheers,
Toby
