You can do something like
http://www.linuxquestions.org/questi...615#post990615

replace the mac with ipaddresses

for exmple

iptables -N droplist
iptables -A droplist -s ! 192.168.1.124 -j RETURN
iptables -A droplist -s ! 192.168.1.154 -j RETURN
iptables -A droplist ACCEPT

iptables -A FORWARD .... -j droplist
