Accessing macOS localhost from Parallels Desktop IE or Edge

Access macOS localhost from IE or Edge within Parallels Desktop

This issue is so infuriating that I'm going to take some time to write about it.

  1. MOST IMPORTANT. Your local development server must be bound to IP address 0.0.0.0. Some do this by default, but many don't. You need to make sure that you run your local server with correct IP bindings. You may need to provide additional flags to your serve commands e.g. polymer serve --hostname domain.local, hugo serve --bind 0.0.0.0. If you use a named domain like domain.local, it has to be defined in /etc/hosts and pointing at 0.0.0.0.

  2. My Parallels setting is using Shared Network, nothing special there.

  3. Open macOS Terminal and type ifconfig. Look for the value under vnic0 > inet. It is typically 10.211.55.2.

  4. You can use this IP address from IE or Edge in Parallels Desktop. Don't forget the port number and protocol, e.g. http://10.211.55.2:3000

  5. It's annoying to remember this IP all the time, so you can edit C:\Windows\System32\drivers\etc (search for Notepad app and right-click to Run as Administrator, then search for this file from within Notepad so that you can actually edit it) and give that IP address a name, e.g. localhost.mac

This just saved my life. For those using Rails, here's how to set the IP: rails s -b 0.0.0.0.

Same thing ! You saved my day, thanks for that !
For Angular users, it won't work using ng client by default !
You have to launch your ng serve with the following parameters : ng serve --host=0.0.0.0 --port 4200
So basically adding the --host=0.0.0.0 parameter fixed everything on my side.

You can find the detailed explanation here

I'm serving angular 2 app (on macos) with command ng serve --host 0.0.0.0,
then I'm reffering from IE 11 (parallels) to url http://10.211.55.2:4200 and everything works fine.

but I want to modify hosts file and map localhost to 10.211.55.2, so I'm adding line to hosts file:
10.211.55.2 localhost
and when I try to access localhost:4200 from IE 11 it fails to connect

any idea?

Any idea what I need to do if there is no vnic0?

ifconfig: interface vnic0 does not exist

Anyone know how to do this with PHP? I get my local server running like so "php -S localhost:8000"

Thanks for this, this really helped me out.

@joshcoast according to http://php.net/manual/en/features.commandline.webserver.php you can do something like php -S 0.0.0.0:8000, haven't tried it myself.

Thanks. It works fine except when I try to define localhost.mac. You don't write which file to edit, but I assume it is host? I tried to define localhost.mac to the IP that works, but I get 'Invalid Host header'
