How to forward traffic from another port to port 80
I'm using nginx to serve my sinatra application with unicorn.
now as port 80 is already being used, I have setuped this app to listen on port 81.
I can access it via IP:81 but to make a DNS entry, I need to forward http traffic from 81 to 80.
How to do this or clear me if, I'm making a wrong approach.
