At the beginning, a problem with virtual box. I'm running vb on a Windows 8 x64 pro pc with only a wifi connection to my router. I create a new virtual machine configured in bridged mode for installing debian squeeze. The problem is that during installation DHCP seems not working.
So after a bit of reflection and search on internet, I suppose :
the real machine and the virtual machines have 2 différents mac addresses. With a cabled network adapter everything works fine because it's configured in promiscuous mode by virtual box. Right ?
It seems that a wifi adapter cannot be configured in promiscuous mode so if I use wireshark, I can see the DHCP Discover packet, but not the DHCP Offer. It's logic.
But what I don't understand : if I confugure my vm with the same mac address than my wifi adapter, I tought it would work. But no. I can't still view the DHCP offer packet. Why ? The adapter is also filtering on the ip ?
