Hi,

If you want to redirect all the traffic to specific address, probably we are talking about the ARR feature

  1. Bind IIS to your domain on port 80/443.
  2. Install ARR + URL Rewrite.
  3. Configure a reverse proxy rule to forward traffic to http://localhost:8081.

That way, IIS acts as the front door, and your app continues to run happily on 8081 without conflicts.

 

Regards!
