Ok here is what I know so far. I am bridging an openvpn tap0 device with a eth0 ethernet device. Works just fine. here is how I do that ifconfig eth0 up promisc 0.0.0.0 ifconfig tap0 up promisc 0.0.0.0 brctl addbr br0 brctl addif br0 eth0 brctl addif br0 tap0 dhclient br0 and then any machine that connects to the tap0 device can also get a dhcp ipaddress through the bridge. ok that all said and done that all works great now for the tricky part I want to change the ethernet device to a wireless ethernet device. I am using the madwifi-ng drivers and try to keep them up to date. I think I got it working some of the times and only times I was bridging through wired ethernet first. then I would add wireless and remove the wired from the bridge. But receintly I havn't even gotten this to work the madwifi-ng drivers supposidly allow for seemless bridging and should allow this to work. If anyone has some experience with this I'd like some help. this is what I tried ifconfig wifi0 up promisc 0.0.0.0 wlanconfig ath0 create wlandev wifi0 iwpriv ath0 wds 1 ifconfig ath0 up promisc 0.0.0.0 wpa_supplicant -Bw -Dmadwifi -iath0 -c/etc/wpa_supplicant.conf ifconfig tap0 up promisc 0.0.0.0 then I check till im connected using wpa_cli -i ath0 status to check then I start the bridge brctl addbr br0 brctl addif br0 ath0 brctl addif br0 tap0 dhclient br0 (which gets an address) but all my openvpn clients cannot get an ipaddress I'm not sure why. If there are some trouble shooting steps I'd like to know how to begin. I have tried sniffing ath0 using ethereal. When using ethereal I see dhcp requests from the openvpn clients but no replys. I'm filtering of the mac address of the openvpn clients tap device Its as though madwifi-ng drivers aren't really in promisc mode but when I check with ifconfig it still says promisc Does anyone have any further things I can try to trouble shoot what is going wrong?
