Hi!

I have a Data Guard configuration which goes through a firewall. Oracle*Net is on a proprietary port 5533 which is open from both sides, but for some reason, the standby DB every now and then attempts to use a strange port 55501 which is not open. Needles to say, connection fails and there is an alert. Does anyone know how to restrict the ports used by Oracle*Net? The platform is Oracle Linux 7.5, Oracle RDBMS 12.1.0.2.
