<p>Any ideas? I can only think that it's a networking issue because the same setup I have, same default.vcl, backends.vcl files, with apache installed on the same VM as varnish, works fine. The backend host when separate from varnish in its own VM also works
fine. But varnish cannot connect to it.</p>

You probably know that you have to add in your hosts file where you are<br>
running your browser you have to point the domain you are hitting with<br>
the ip address of your varnish VM, don´t you?<br>
