How to make the webpack dev server run on port 80 and on 0.0.0.0 to make it publicly accessible?

Something like this worked for me. I am guessing this should work for you.

Run webpack-dev using this

webpack-dev-server --host 0.0.0.0 --port 80

And set this in webpack.config.js

entry: [
    'webpack-dev-server/client?http://0.0.0.0:80',
     config.paths.demo
 ]

Note If you are using hot loading, you will have to do this.

Run webpack-dev using this

webpack-dev-server --host 0.0.0.0 --port 80

And set this in webpack.config.js

entry: [
    'webpack-dev-server/client?http://0.0.0.0:80',
    'webpack/hot/only-dev-server',
     config.paths.demo
 ],

....
plugins:[new webpack.HotModuleReplacementPlugin()]
