All,
I have the following running on our server:
for m in xx:xx:xx:xx:xx:xx...about 75 MACs
do
iptables -t mangle -A PREROUTING -i eth1 -m mac --mac-source $m -j ACCEPT
done
iptables -t mangle -A PREROUTING -i eth1 DROP
iptables -t mangle -A PREROUTING -i eth1 -m iprange ! --src-range \
192.168.1.1-192.168.1.74 -j DROP
and encountered a noticable slowdown when I incorporated the above. Can anyone offer suggestions as to how to speed this up? I know that hash tables are out there, but I am not clear on their use.
Thanks,
Jason
