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 ?

I'm not familiar with virtual box, but are you configuring the VM with the equivalent of bridged networking? Also, is the host's firewall on? –  SpacemanSpiff Mar 1 '13 at 13:50
yes, it's configured in bridged networking and the host firewall is on. But I don't think it's the problem because if I turn wifi off and plug a cable it's working. –  tweetysat Mar 1 '13 at 14:34
Even though bridged mode and WiFi in VirtualBox has come a long way, it is still problematic under ideal circumstances. What are you doing that you need bridged mode that either NAT or combined with Host-Only networking can't accomplish? –  Goyuix Mar 4 '13 at 19:56
