I don’t believe I do. I can connect remotely with my first database that uses the default port 5432 and not with the second one using port 5436. However, I can connect locally to the database and perform any task.

You can check it with iptables -L if so, you can stop it with service iptables stop and then check again whether the db is accessible remotely or not.
