I recently got a node.js app up and running on my localhost. Basically, there's a client-side app that runs on my xampp installation, and a server.js that the client connects to. I uploaded the server files to OpenShift and tried to run the app, but got an error because the port wasn't forwarded and therefore couldn't even listen.
I need to know how I can forward specific ports and what ports I can bind the server app to.
