Those with a RHEL subscription can find a Red Hat knowledge base articel 
under

                  https://access.redhat.com/solutions/1121463

about the question "How to filter outbound or outgoing network traffic 
in RHEL7?"

It pretty much explains how to achieve outbound filtering using 
FirewallD.
