Mean Stack install on port 80 or or under iis

I have a Mean stack application that works now on Node Js and port 3000. I have a Windows Server 2016 and i need to deploy .Net Apps, so i need IIS. I can't make run both web servers on port 80 but i don't want the users are forced to type the port where running my Mean app. I tried to work with iisnode, but with no success and i also read about reverse proxy in order to redirect the requests on the port 80 to another port. Both solution could be valid, but, before spend other time on the wrong direction i ask what is the best practice in this case. Thanks Max
