Hi @efabiancj,

Before I can provide you with some examples, I’m not sure I entirely understand, please correct me if I’m wrong. So you have two droplets one of which is a Postgres droplet. You want to allow connections from the droplet that doesn’t have Postgres to the one that does only from the sad IP address, is that correct?
