#5949 closed defect (fixed)

Bridged networking broken in Virtualbox 3.1.2 for Windows 2003 R2 host (similar: Ticket #5924)

Reported by: Maxim Owned by:
Component: network Version: VirtualBox 3.1.2
Keywords: Cc:
Guest type: Windows Host type: Windows


After upgrading from VirtualBox 3.1.0 to 3.1.2 (no further system changes) the bridged network has broken.

Ticket #5924 seems to describe exactly the same problem for Windows 2008 R2 host.

Host: Windows 2003 R2 (x64)
Guest: Windows XP SP3 (x86)

After the mentioned update the guest still has full (working) access to the internal network (192.168.x.x). If trying to access the internet the guest displays messages saying the computer would have no internet connection.

  • Trying to load a website from the guest fails although the same website loads perfectly from any other (real) computer from the internal network (or from the host)
  • Pinging a website from the guest yields 50% packet-loss, while being 100% accessible from any other PC from the internal network (or from the host)

Sorry, I have to correct myself: The right version I was upgrading from is 3.0.12.

What third-party networking-related software (like VPN, Antivirus, Firewall or virtualization software) do you have installed on your host?

comment:3 by Maxim, 15 years ago

Following software is running on my host:

  • Routing and RAS service (RRAS)

This service has not changed since VirtualBox 2.x times.

  • The antivirus I have running there has all network, mail and real-time modules disabled. I use it solely to inspect suspicious files from explorer's context menu.

There it is. I have no VPNs, no firewall (beyond RRAS), no virtualization software or anything similar running on the host OS.

...and like I said: nothing has changed, except upgrading to VirtualBox 3.1.2 from 3.0.12

I'm asking because the problem might be caused by some system re-config during the install. Does downgrading back to 3.0.12 solves your issue?

comment:5 by Maxim, 15 years ago

Sorry, but I cannot downgrade back to 3.0.12 anymore. After reading ticket #5924 I decided to completely restore the host and the guest from a back-up still using 3.0.12. :-(
Only in case it's really, really important and really, really necessary I could upgrade to 3.1.2 again and then downgrade back to 3.0.12.

have seen this on my Windows 2008 32bit host (prev win version). i think it is related to vbox drivers don't understand how to work with RRAS role installed. (there are virtual VPN interfaces in RRAS).

Still experiencing the same problems with VirtualBox 3.1.4. Rolled back using a backup to 3.0.12 once again.
