This app wont listen to my network interface

I am having an issue getting this app to listen on my network interface. 

I already modified my coffee.config file to this. Anything else i'm missing here?
        templates:
            defaultExtension: 'hbs'
            joinTo: 'static/js/app.js'

```
server: '0.0.0.0'
    base: '/facewall'
```
