Try something like:

iptables -A INPUT -s a.b.c.d -m mac --mac aa:bb:cc:dd:ee:ff -j ACCEPT

Where a.b.c.d is the IP address and aa:bb:cc:dd:ee:ff is the MAC address of 
the machine you want to allow access to the firewall system.

You need to have compiled mac address matching into your kernel, or loaded the 
appropriate module.

See "man iptables" for more info.
