Model answer
What a good answer should say
- The router forwards matching traffic to the internal web service specified in its port-forwarding rule.
Explanation
Why this works
A port-forwarding rule associates an incoming port with an internal destination. When traffic matches that rule, the router sends it to the selected service rather than treating the port as having no destination.
