[arch-general] problem while bridging network

[ludovic coues]

hi listmate,

I'm posting 'cause I have some problem when I bridge a connexion.
I wanna set up a virtual machine with windws 7 to play eve online (no
support for linux at this time, and I can't make it run on wine).

So I've follow the wiki for setting up network with the virtual
machine. But now, I'm starting my computer with eth0 and vbox0
bridged, but I can't use my wifi connexion on wlan0.
If I delete the bridge with a «brctl delbr br0», I can connect to the
wifi through wlan0, but my VM haven't any network.
To be exact, I can connect me to my personnal network, but this have
no internet connexion.
Weird.

If any one might help me with this, it would be nice.
