Hi, is it possible to use iptables as dhcpd ? I mean: iptables -t mangle -A POSTROUTING -m mac --mac-source "some mac" -j SNAT --to "some ip" I know mac-source is not avalaible from postrouting chain, but is there another way to use it. I'm already using mark for bandwidth control, so i can use mark so SNAT. Any idea, Michael Plourde
