Mac Filtering in REDHAT-el5

Need help to filter the MAC address for the specific ipaddress., HOW??

I had try the rule for:

iptables -A FORWARD -i eth1 -s 192.168.129.57 -m mac --mac-source 00:02:6F:48:8A:85 -j ACCEPT

But Not working now and if you have any alternate solution Help us.:confused::confused:

When you say it is "not working", does that mean that packets from this mac/ip are not being forwarded? Or do you mean that invalid packets (which do not match the ip and mac) are being forwarded?
