Consider the scenario, where you are having the REST api / Web API hosted on the server which isn't connected to the internet and you wanna expose those api to the world. so you create another server that is connected to the outside network ( most cases internet) and on that server you have to configure URL Rewrite that would route the traffic to your secured web server. so that your secured web server isnt expose to the internet. One of the scenario is to setup the hybrid connection between your on prem and azure network through Azure Service Fabric reverse proxy implementation, where you can exponse your internal data to the services on Azure.

Port forwarding is the networking component working at the router level. Consider the scenario there is incomming request if its for port 80 or port 443 you may want to route the request to the web applicatoin server. If the request is for 1433 or 1434 you may want to route the request to the sql server.
