[vbox-dev] 'bridged adapter' issue.

[Maarten Hoes]

Hi,


Im running into an issue were it appears as if my bridged adapters in my
CentOS 7 guest VM's no longer are able to contact the default gateway. For
example, when issuing a ping to that default gateway from within the guest,
it fails. (Other network activity also fails to work, appearantly because
of this. Pinging the default gateway from the host works as expected.). On
the other hand, the same device (my ISP's router/modem) seems to be
receiving DHCP requests and issuing DHCP reply's just fine, because the
guest gets IP addresses assigned with DHCP.

I tried downgrading from 5.0 to 4.3.30 and 4.3.28, but that did not change
the behavior. Setting the bridged adapter to 'NAT' for the guest does make
the issue go away.

My host is Windows 8.1, and the guests are CentOS 7. VirtualBox 5.0.

Also, bridged adapters with VirtualBox 5.0 used to work, so I suspect some
Windows update (or other software configuration change on my box).

I really have no idea on how to troubleshoot this issue further. Any and
all input is appreciated.


Thanks,


- Maarten
