MAC Address filter on wireless interface

[Steve Comfort <steve@xxxxxxxxx>]

Hi All,

I have been trying to get MAC address filtering to work on our wireless 
card - so far without success :

The rules I am using are listed below :

    for M in $(cat /etc/mac.allow) ; do
        $IPT -A INPUT -i $WIFI_IF -m mac --mac_source $M -j ACCEPT
    done
    for M in $(cat /etc/mac.allow) ; do
        $IPT -A INPUT -i $WIFI_IF -m mac --mac-source ! $M -j DROP
    done

(I do have CONFIG_IP_NF_MATCH_MAC turned on).

I'm running on an ARM processor with kernel 2.4.21-rmk1

Is it in fact possible to filter on MAC addresses over a WiFi interface, 
or am I doing something stupid?

Best regards
Steve Comfort
