How to run a node server with forge?

Does anyone has experience with running isomorphic/universal JS apps in production? I try to run my project (a react/flux app) in production. It works perfectly on my local machine (even in production mode), but not on the server...

I do following tasks:

1. Deploy all files to the server (with deploybot or envoyer)
2. Via SSH (forge@ip) -> Run npm install
3. Build js/css etc. (npm run build) with webpack and gulp
4. Start node server (npm run start)

• The server seems to actually run fine, but it is running on Port 8080 and I have no idea how to reach it. Where do I have to forward it to port 80?
• As I start the server in teminal via SSH, it shuts down after I close the terminal. How can I run the server persistently and automatically?

Thanks!
