That's not the problem. You need to allow connections to the port mapper
daemon as well as to the Erlang nodes. The former is fixed (defaults to
4369) but can be changed via ERL_EPMD_PORT. The latter is random and can
be controlled via the inet_dist_listen_min and inet_dist_listen_max
Erlang parameters.
