How effective do you find this to be given the relative simplicity of spoofing a MAC. I understand most users won't know how, but most bad guys will and they're the ones to be worried about.

I would probably do it with MAC address filtering.

From: Evan Brastow [mailto:[email protected]]<mailto:[mailto:[email protected]]> Sent: Tuesday, February 21, 2012 12:35 PM To: NT System Admin Issues Subject: Limiting DHCP Hi all, I've recently set up a wireless router in the DMZ on our firewall. This will allow consultants, salesmen, etc... to have a connection to the Internet when they come in, with no connection to our network. Now, however, in order to take the final step in this process and be sure someone can't just plug into a network port, it would seem I need to do one of two things: 1) Stop our DHCP server and give all network devices (less than 50 or so) static IP's. or 2) Restrict DHCP to only listed MAC addresses. So, my questions are - which of these two would be easier (does it really make much difference?) or is there a third option I don't see?
