iptables can be used to filter packets based on MAC addresses.

The Packets which i am getting only contain Ethernet header (Source MAc , Dest Mac , Protocol) , i have tried using Iptables but it does not filters the packets .
i think iptables works on layer 3 .

Please Suggest me some answers

Actually, though intended for ethernet bridging, it seems the ebtables interface should do what you need.

u can't do it using IP tables. they work at L3. why don't you write a simple ethernet bridge for this purpose.

I could be mistaken here, but I always thought MAC addresses could be specified using iptables just so long as your kernel is compiled with CONFIG_IP_NF_MATCH_MAC support.
