during work on the SELinux policy changes, I’ve noticed that Puma listens on 3000 tcp by default. This port is already assigned to
ntop_port_t for application
ntop. It is also used by few other apps  and it appears to be the default Rails development port.
Since there is still some time to change this, I would like to open up discussion about picking a different higher-range port that is not used officially, unofficially or even assigned in SELinux base policy. The only reason I have is that reusing SELinux port assignments can bring huge pains when these get reassigned in the base policy. @packaging
