I want to use WRAP-boards as wireless bridge and the cpu on it is quite weak.
So the idea was to use the hardware encryption of the atheros cards to do most
of the work. WDS and WPA is definitley something i'm looking forward to.
Yesterday i tried to simply mimic the setup of hostapd when the "bridge=" parameter
is used and hardcoded the ifname of my bridge in the wpa_supplicant_driver_init
- wpa_s->l2 = l2_packet_init(wpa_s->ifname,
+ wpa_s->l2 = l2_packet_init("br0",
This time wpa_supplicant has been working while the interface was part of the
bridge. I didn't manage to get packets from an wired client over the wireless link,
but that's where i asume that the MAC layer NATing is needed.
