I am trying to setup a Win8 box as a "reverse proxy" web server using IIS.

The goal is as simple as it gets. I do not need subdomains to go to different servers, but rather to redirect all port-80 and port-443 (HTTP and HTTPS) traffic to http://localhost:2080.

I have been trying to get IIS to do that for a week now, without any success. I feel depressed and worthless
Is there any good soul out there who would be willing to explain me, in a few steps, how the above can be accomplished? Many many thanks in advance!
