Although I haven't tried it, I would assume you should be able to accomplish
it by going to Services: DHCP and adding an entry for that person's MAC
address and forcing it an IP address based on that MAC.  Who is to say then
the person won't spoof a MAC address then and achieving the same result.

Subject: [m0n0wall] How to deny a client multiple dhcp addresses

Hello all,

I have a client pulling 2 dhcp addresses on the same mac address.  How
do I go about restricting the dhcp service to 1 address per mac?

Thanks,
Bryan
