Bridge networking reports duplicated ip address

I'm running virtualbox 3.0.6 on my windows xp host and i'm trying to use bridge networking into my guests. I'm trying to bridge the wireless adapter. No one of the guest could connect to any ip adrress, and as an additional input, all the windows guests reports duplicated ip address. I did some check and i discovered that the problem seems to reside in the arp protocol. As soon as the guest tries to connect to an ipaddress that is in the same subnet, what happen is that into the guest and into the host operating system the ip address is registered with the macaddress of the host adapter. If the destination ip address is on a remote network, that the macaddress registered is the one of the default gateway.

To solve the problem i had simply to manually delete the wrong arp entries from the host, guestes and remote systems and registers the macaddress manually using the arp -s command.

So i'm suspecting a problem with the bridge driver that fails in some way managing the macadrresses.
