May be stupid question.
Oracle database is behind Firewall.
Is there any place in Documentation whee explained which ports should be opened on Firewall for
- oracle listener
- oracle connections
Thank you in advance
It depends on what ports you're using. By default, the listener operates on port 1521. Therefore, your firewall should allow incoming to port 1521 and outgoing from port 1521.

Thank you for reply.
But? as far as I understand, listener only establishes a connection between client and server, and then communication between client and database flows on another port? Yes or mauy be I am wrong?
