Distributed nodes in different networks

Hi guys, I have a question
I’m trying connect two distributed nodes with differents networks, but in always return false
these was my attempts:
pc1: iex --name one@william --cookie secret_token
pc2: iex --name two@uriel --cookie secret_token

pc1: iex --name one@william --cookie banana --erl ‘-kernel inet_dist_listen_min 9500’ --erl ‘-kernel inet_dist_listen_max 9500’
pc2: iex --name two@uriel --cookie banana --erl ‘-kernel inet_dist_listen_min 9500’ --erl ‘-kernel inet_dist_listen_max 9500’

pc1: iex --name one@161.22.57.2 --cookie secret_token
pc2: iex --name two@189.4.78.45 --cookie secret_token

Does anyone have any idea?
maybe it’s necessary open some network port

Note that the distributed Erlang protocol is really not designed for use over a WAN connection between the nodes, both in terms of its latency tolerances and mesh behavior and in terms of security considerations.

Right, to steal a joke from LYSE, distributed Erlang’s security protocol looks like this:

Open port 4369, that’s erlang port mapper daemon (epmd) https://erlang.org/doc/man/epmd.html

You may also have to activate other, higher port ranges in the firewall depending on your service

you can do erlang distribution over TLS, which is not horrible, if I understand correctly, but latency is still an issue.
