Hello, I am getting stuck about the bridging configuration on a VM host
(Virtualbox 2.0.6) running opensuse11, wherein I am attempting to use
several guests, as XP, Solaris 10 and Opensolaris 2008/05.

What I want is to bridge the virtual interface "tap0" with the wifi
interface "wlan0".

Please note: This kind of bridging works perfectly on a "mirror"
environment, wherein I use a VM host running windows XP, along with a
Solaris 10 as guest.

I followed several how-to and instructions, as the ones reported here
'VirtualBox - openSUSE' (http://en.opensuse.org/VirtualBox) as well the
ones we can read onto the Virtualbox Help GUI.


Unluckily I get the following issues:
- My bridge "br0" interface never starts on boot; I have to manually
start it with "ifup br0" also if I have the ifcfg script on place
- "br0", whenever starts, pull down the connection from wlan0,
managed by Networkmanager, which lacks the connectivity from the
Internet, as well as the routing toward the outside
- I don't understand why into many "/etc/sysconfig/network/ifcfg-br0"
is present just one interface into "bridge-ports", when I suppose to
have at least two: the primary and the virtual.
- All the issues I revealed above, attempting to use the wifi
interface "wlan0" are exactly the same also if I try to use the
primary ethernet "eth0"
It seems that something is lacking on my configuration.
I would like to know if someone have been able to configure and use a
network bridging on Virtualbox host running opensuse11 and a guest
running other O.S.
both using the ethernet interface or wifi.

Regards
