I'm trying to bridge a wired network and a wireless network, but I'm having some trouble. No traffic seems to be passing through the bridge. When I issue a "showmacs" command to brctl, I am able to see MAC addresses from both networks. I am also able to ping both networks from the bridge machine. When I issue a "showstp" command to brctl, the wireless access point that my card is connected to is shown as the root bridge no matter how low I set the bridge priority. If I tell my wireless card to act as the master, the bridge seems to function perfectly. The card I'm using is a D-Link DWL-520 Rev E1 with a Prism2.5 chipset using the HostAP drivers. I read in the FAQ page that some wireless cards cannot act as bridges because they are unable to spoof MAC addresses. I do not believe this to be the case with my card. I am able to change my MAC address without problems by issuing the following command: ifconfig wlan0 hw ether XXXXXXXXXXXX The card functions normally with a fake MAC address. It'll even show up on my access point's station list as the fake address. So am I doing something wrong? Should this work, or did I misunderstand the FAQ? Is altering the MAC address a thorough enough test of whether my card is capable of being a wireless bridge? The bridge machine I'm using is an older PPC Macintosh running Debian unstable. Could the architecture be a problem? If it is impossible for me to bridge the networks when I am a wireless client in managed mode, would it be possible to bridge the hardware access point and this linux box functioning in master mode? Thank you for your time, TC PS: If this is the wrong place to post these sorts of questions, I apologize for the inconvenience.
