Port forwarding
A DNAT rule that maps an external (public) port on the router to an internal (private) host+port, so external traffic can reach an internal service.
How this shows up at NCAE
See NAT. Without correct port-forwarding for 22, 53, 80, 443, 445, 5432, the scoring engine directly cannot reach any of your external services.
