When the ubuntu system is connected via ethernet, and the virtual machine works with network attached to the host interface, the network works. When the ubuntu machine works with the wifi interface (wlan0), the hosted system does not work. It does not get the network address and, of course, does not work on the network. The following are commands I issue (as root) to make the ethernet working, and it works: tunctl -t tap1 -u claudia brctl addbr br1 ifconfig eth0 promisc brctl addif br1 eth0 ifconfig br1 192.168.1.202 up brctl addif br1 tap1 chmod 666 /dev/net/tun The same commands, when applied to the wlan0, block the network interface and the hosted system results disconnected: tunctl -t tap1 -u claudia brctl addbr br1 ifconfig wlan0 promisc brctl addif br1 wlan0 ifconfig br1 192.168.1.237 up brctl addif br1 tap1 ifconfig tap1 up chmod 666 /dev/net/tun </blockquote><div> I think the steps you are taking are correct. Which version of VB are you using ? I remember that the older versions had a known issue with wireless bridging. Don't really remember if that was sorted out , but here's a link to help you out : <a href="http://www.savvyadmin.com/virtualbox-wireless-bridging/">http://www.savvyadmin.com/virtualbox-wireless-bridging/</a> Thanks, Raseel <a href="http://raseel.in">http://raseel.in</a> </div></div>
