My Linux machine (A) is connected with some Wifi AP over my wireless device (wlan0). I want to give some other Linux machine (B), which is connected to me by ethernet (eth0), access to this network. I do not want to use NAT. So I create a bridge device and bridge wlan0 and eth0.

This does not work. I suspect, the main reason lies in the fact, that B’s MAC was never associated to the AP. So it would simply drop B’s packets.

If B would know at this point, that his ethernet is bridged to wireless, could it associate to the AP itself? Is it necessary to know the network credentials to do this (after all, it is bridged over my already-secured connection)?

If this is not possible, could I somehow associate B’s MAC for it? And are there other obstacles in this scenario?
