dhcp flooding, rogue dhcp, network based attacks.

i'm currently attending a ccna course and last time we discussed aboud network based attacks.
at home i have a quite big test network with a server and several cisco devices.
i would like to test these different attacks especially dhcp flooding in order to set up a rogue dhcp that set my pc as a rogue gateway for  a final MITM attack.

seems easy but i haven't beebn able to find a tool that automatically send a dhcp request with a modified MAC addres.

Is there something like taht? a packet generator that automatically change your mac address? i tried colasoft packetbuilder but, allso i wonderfull for creating single packets, cannot automate the proces.

then, when done this and setted up a rogue dhcp, that seves configuration with myself as defoult gateway, how can i route it to the router transparently?, after sniffing ofcourse.

thanks in advance and don't worry, i'm not a script kiddy asking how to hack the pentagon!
