I work in an Ubuntu 20 VM, running apache2, but would like to access my site in Windows 10, I 've set up the vhost, that's fine, but using port 9000 doesn't work outside of the VM. This is the config which is working in the VM:

devServer: {
      contentBasePublicPath: '/',
      publicPath: '/theme/',
      host: 'some.vhost.co.uk',
      allowedHosts: ['0.0.0.0'],
      compress: true,
      hot: true,
      liveReload: false,
      port: 9000,
      proxy: {
        '/': 'http://localhost:80'
      },
    },
