title: How to get access to webpack-dev-server with external IP
body: <p>I've got my simple login website fully coded and functional on the webpack dev server. how can i display it with my external IP? I've already port forwarded my router on port 9000 but when i tried www.myIp:portnumber its not working.
  Below is my webpack config for the webpack dev server.</p>
  
  <pre><code>//Webpack config
  module.exports = {
    entry: './app/main.js',
    output: {
      path: './app',
      filename: 'bundle.js'
    },
    devServer: {
      inline: true,
      contentBase: './app',
      port: 9000
    },
    module: {
      loaders: [
        {
          test: /\.js$/,
          exclude: /node_modules/,
          loader: 'babel'
        }
      ]
    }
  }
  </code></pre>
