vagrant provisioned virtualbox cannot access the internet when booted up with an active VPN connection on the windows 7 host - windows

Question

I have a problem with networking while setting up a development virtual machine
The host environment is:
Windows 7x64
Vagrant 1.7.2
Virtualbox 4.3.20 r96997
has an active WLAN internet connections
can connect to a VPN
The relevant sections from the Vagrantfile are:
ENV['VAGRANT_DEFAULT_PROVIDER'] = 'virtualbox'
Vagrant.configure(2) do |config|
config.vm.box = "ubuntu/trusty64"
config.vm.define 'crm' do |node|
node.vm.network :private_network, ip: '192.168.56.2'
end
end
With this, the guest machine has two network interfaces:
eth0: NAT
eth1: the private network
After a vagrant up the machine is always accessible through the private IP.
However, if at boot time the VPN connection
is active, then the guest machine cannot access the internet
is not active, then the guest machine can access the internet
On the host machine, with an active VPN connection, both public and VPN-restricted hosts are accessible.
Question: how should I modify the Vagrantfile to ensure that the guest machine always has internet access, regardless whether it was booted with an active VPN connection on the host machine or not?
Update:
adding
config.vm.provider :virtualbox do |vb|
vb.customize ["modifyvm", :id, "--natdnshostresolver1", "on"]
end
solves the internet connectivity issue, however, it brings the boot time of the guest machine to barely tolerable (many minutes)

Answer 1

ok. i had the same problem but i am using windows. i did fix it. what i did is that opened virtualbox.
go to settings
select network
change second adapter
select under " attached to: " ' Host-only Adapter'
under name. i selected " virtualbox host-only ethernet apdapter " do not select the name that have numbers at the end of the name example : #1, #2 and so on.
i went to my device manager and delete all the virtual network drivers "not your physical network drivers". again this was in windows 8.
i restart my pc
confirm my chance have applied
i vagrant up on my project directory and it was working
