How can I allow access outside the localhost at Angular2? I can navigate at `localhost:3030/panel` easily but I can not navigate when I write my IP such as `10.123.14.12:3030/panel/`. Could you please allow me how to fix it? I am not using `npm` (node project manage - node install/node start ) to install and run the project. If you want, I can provide my `package.json` and `index.html`.
