Please, provide details about your configuration. VBox.log from the run that exhibits the problem, ip configuration of the host and of the guest, etc.

I experienced the same problem - as described here:  https://forums.virtualbox.org/viewtopic.php?f=1&t=68786&start=30#p328115

Using VB since 3.x, got 40+ guests set up, nearly all of them with bridged network and static IP addresses. After upgrade to 5.0.0 r 101573 all bridged network just stopped working, regardless if that is linux guest or widnows guest.

My host is Windows 7 Professional 64b 16GB

Issue experienced on: CentOS 64b, without Guest Additions (it never has them installed before) Windows 10 64b build 10166 with updated Guest Additions Windows Server 2008 R2

VBox.log attached (with my username as preffix). I set up a brand new Centos_test instance using Centos 6.5 64b minimal iso.

Please find attached another log file - win10_VBox.log

I booted guest - Win10 - with network set to bridged. Once booted I started ping -t google.com. Then switched network to NAT and after couple of successful pings back to bridged. Ping results can be found here:  http://i.imgur.com/0GetuVC.png

Ok, I tried all possible tricks:

  • laptop [A] has VB 5.0.0 r 101573 installed on Win8.1 64b
  • PC [B] has VB 5.0.0 r 101573 installed on Win7 Pro 64b
  • on [A] and [B] I have CentOS 64b set with network set to bridged. Static IP. On [A] - I got full internet connectivity, on [B] I can access only local resources - that is 192.168.1.1 with netmast 255.255.240.0.
  • exported Centos from [A] to .ova and imported in on [B] - not working in new place
  • exported Centos from [B] to .ova and imported in on [A] - full internet access, no problems
  • uninstalled VB with Revo Uninstaller Pro on [B], restarted my PC, installed VB 5.0.0 r 101573, just added tag <MachineRegistry> to VirtualBox.xml - problem still occurs
  • unintsalled VB with Revo Uninstalled Pro on [B], restarted my PC, installed VB 4.3.30 r 101610, just added tag <MachineRegistry> to VirtualBox.xml - problem is gone!

There's a similar report #14395 that says the interaction with the firewall was causing the issue for the reporter. Anything similar in your setups?

I tried to reinstall all, it didn't work (with revo)

I then shutdown my bitdefender firewall and set back to bridge with "promiscuity" authorized all to have the network working properly.

Replying to vushakov:

It could be as I also have Bitdefender on my host. Unfortunately I'm unable to verify it at the moment as after a number of attempts I just downgraded my VB installation to latest 4.x version. I will try to upgrade it and test the Bitdefender behaviour.

Please note that I was able to access all local network resources (192.168.x.x range) from guest, but unable to access anything outside my network.

Since you are on a wired connection and have other physical machines connected, please, can you do a packet capture of a guest acting up, but taken on another physical host on the same network? A ping or http connect to something local and to something remote? If privacy is an issue, you can limit the capture to 64 bytes and provide it privately instead of attaching it here.

I already did that once I had VB 5.0.0 r 101573 installed. I ran Wireshark on host and sniffed traffic from guest. I'm not a Wireshark guru, but was able to notice that there was no activity when I was pinging / wgeting / telneting any remote host.

Once I will have a minute, I will install newest 5.z release and run Wireshark on host to sniff traffic from guest and will share the log file.

Please, do the capture on a different machine, not on the host. I'm requesting that for a reason.
