Nat networking in Virtual Box for Windows 7 host and Ubuntu 16.04 guest not working all of a sudden
Nat networking in Virtual Box for Windows 7 host and Ubuntu 16.04 guest not working all of a sudden
I had installed virtualbox on Windows 7 host. Additionally I installed an Ubuntu 16.04 32 bit VM guest. For the network adapter I chose attach to Nat Network.
I have been using this configuration both behind a corporate proxy and on a home adsl router and both worked fine. Up to last week I had internet connection via the VM.
Unfortunately when I checked today I couldn't connect to the internet any more. When I ping the google DNS server 8.8.8.8 I also got Destination Host Unreachable.
I updated the Virtualbox and to its latest version 5.1.18r114002 but no success. I also added Google Dns servers 8.8.8.8 and 8.8.4.4 either on host or no guest but the internet
access could not be retrieved.
Has anyone any idea why this may have happened?

Hi,
I unfortunatly face the same issue since the 14th of march. After a reboot no way to access network from a Ubuntu 14.4 without any change on the host or the guest network setting.
There was a windows update on this day but after a restauration of the system before this update the issue persist.
Guest: Ubuntu 14.4 64 bits
Host: Windows 7
Virtualbox: 5.1.10

@dk1301
I have no clue since you didn't attach any logs. But the answer may be the same as the one below.
@Mondraker
Your Lavasoft certificate has expired and the software cannot load. Either uninstall the Lavasoft software or update it.

I should have been more specific. The "VBoxSVC.log" is not an appropriate one in this case. Start the VM. When it fails, right-click on the VM in the VirtualBox Manager, "Show Log". Then either the "VBoxHardening.log" of the first "VBox.log".
Actually zip them both together and attach that zip file.

Hi Socratis,
Sorry for the duplicate. And actually the issue was the same than the one of the post you mentionned above. So indeed unsinstalling the Web companion fixed the bug.
Thank you for the support

Hey dk1301,
I took a look at your logs. I can't see anything glaring. Could you please post the output of the following commands from a Command Prompt in your Win host? The first one is just to get you to the "VBoxManage" directory:

Re: Nat networking in Virtual Box for Windows 7 host and Ubuntu 16.04 guest not working all of a sud
Problem #1: you chose your NATService to have the same range as the built-in NAT, 10.0.2.x. Did you have any particular reason for that, or was it by accident? In any event, try to change the range to something non-conflicting, like 10.35.97.x.
Problem #2: you have two identical DHCP servers. I really don't know how it affects things, but "I've got a bad feeling about this".
I suggest to delete the NatNetwork, and then cleanup the DHCP servers situation. Then re-create the NatNetwork with a suggested IP range as above. Repeat the commands and make sure that everything is in order. See how it goes...

Re: Nat networking in Virtual Box for Windows 7 host and Ubuntu 16.04 guest not working all of a sud
- Open an elevated Command Prompt (right-click, Run-as-Administrator) and execute the command:
sfc /scannow
- If it comes with errors that can't be fixed, try to do the same procedure after a safe boot.
- If that doesn't work, try to disable McAfee.
- If that doesn't work, try to uninstall McAfee completely.

The result of sfc /scannow was :
Unfortunately since I'm working on my company's pc the uninstall or disabling of McAfee is not an option.
Anyhow than for your help so far.

- See if you can update McAfee.
- See if you can disable parts of it, especially the firewall.

Re: Nat networking in Virtual Box for Windows 7 host and Ubuntu 16.04 guest not working all of a sud
Hi all, I found a solution for my problem. I changed the adapter from the default intel to the AMD PCNet PCI II (Am79C970A).
