Why? There is very little security in a MAC address as they can be faked  
just as easily as IP addresses (in a LAN context). If you need secure 
communications with local machines then you'd be better off looking at    
VLAN, seperate cabling or VPN. Those are designed for security, MAC's are

I work in Sao Paulo, Brazil, in a ISP, and in our site we have a Linux
Server (Conectiva Linux - A Brazilian version of Red Hat Linux). We need
to limit the packet input in this Server based on the source MAC Address
of the packet. Unfortunately, we have no way to filter the packets based
in the source IP Address :(. We need a MAC Address filter, where only   
the MAC's in a Access List can access the services on this Linux server.
Is there a Linux feature, or a software, or anyone that knows the Linux 
Kernel and can give us some tips on how to develop that kind of filter?
