Add Reverse proxy rules

Setup a Reverse Proxy rule using the Wizard.
Open the IIS Manager Console and click on the Default Web Site from the tree view on the left. Select the URL Rewrite Icon from the middle pane, and then double click it to load the URL Rewrite interface.
Chose the ‘Add Rule’ action from the right pane of the management console, and the select the ‘Reverse Proxy Rule’ from the ‘Inbound and Outbound Rules’ category.
