title: Ionic mobile browser testing is not working
body: <p>I try to use mobile browser testing with ionic. I'm connected in the same Wifi as my iPhone and checked my IP-Address with the following command: <code>ifconfig |grep inet</code>. When I'm running ionic server with the command <code>ionic serve</code> I'm not able to open my ionic app on my iPhone using my IP-Address and the specified port from ionic. Do I have to enable something else on my machine? I also tried different ports without any success. </p>
