Once again after major windows update my virtualbox networking went down the drain...

My VMs are starting and I can connect to them via vagrant port forwarding. But I cannot reach them from windows host on the internal network (pinging them on 10.0.0.30). VMs have connection to the outside world. Also VMs (I have two with the same vagrant file, differs only in last IP segment) can ping themselves on static IPs in this private network.

I suspect it is either windows firewall or incorrect routing on host. But I cannot find a way to make it work again.

Details:

Host: Windows 10 Pro with VirtualBox Guest: Ubuntu (box: ubuntu/xenial64)

Vagrant file:

# -*- mode: ruby -*-

# vi: set ft=ruby :


Vagrant.configure(2) do |config|
  config.vm.box = "ubuntu/xenial64"
  config.vm.synced_folder ".", "/vagrant", mount_options: ["dmode=777,fmode=666"]
  config.vm.provider "virtualbox" do |v|
    v.memory = 8192
 v.customize ["modifyvm", :id, "--natdnshostresolver1", "on"]
  end

  config.vm.define :dev do |dev|
    dev.vm.hostname = "local-dev" 
    dev.vm.network "private_network", ip: "10.0.0.30"
    dev.vm.provision :shell, path: "bootstrap.sh"
    dev.vm.provision :shell,
      inline: 'PYTHONUNBUFFERED=1 ansible-playbook \
        /vagrant/ansible/dev.yml -c local'


  end

  if Vagrant.has_plugin?("vagrant-cachier")
    config.cache.scope = :box
  end

  if Vagrant.has_plugin?("vagrant-vbguest")
    config.vbguest.auto_update = false
    config.vbguest.no_install = true
    config.vbguest.no_remote = true
  end


end

Any assistance would be greatly appreciated as I am about to loose last hair over this thing...

I recall that some time ago I was solving something like this by adding missing routing somewhere (guest or host) but can't remember what exactly nor can I find any help online...

[EDIT] - Resolved, after 2 days of biting keyboard over it...

The problem was some weird interaction between networking stack, virtualbox adapters and NordVPN/NordVPN TAP Driver. Everything was working fine together before last windows update and went belly up after that.

I have uninstalled NordVPN and related TAP driver, uninstalled network interfaces and let windows reinstall them after restart. Now it is working as expecting. I will now try to reinstall Nord VPN on top of it and see if it still works.

  • Ah the wonderful world of the ever evolving Windows 10, that has to suck. I hope you find a solution, if you do, be sure to come back and post it as an answer. – Moab Jun 12 '18 at 18:37
  • By now I have removed all virtualbox network adapters, uninstalled and reinstalled virtualbox and started new box with much simplified config. Still no joy. Will update if I find some solution for this – wciesiel Jun 13 '18 at 7:15
