If you want to do MAC filtering, add the following to the sample above:
[label=\file{/etc/network/interfaces}]
wireless-macmode 2
wireless-mac 00:01:02:03:04:05 06:07:08:09:0a:0b
this enables the filter and defines the list to contain addresses that should be allowed.
If you already use VPN to secure your connection, you can just use an unencrypted setup and setup the firewall on your embedded device.

WLAN with WDS nodes, the WDS nodes need to have the same SSID, channel and encryption parameters. The WDS connection is separetely secured via WPA1 and AES. WPA2 for WDS connection security is _not_ working.
