As someone already pointed out, DHCP is a broadcast. Routers do not by nature forward broadcast traffic. A $50 (or less) Linksys (or other brand) broadband router sitting between the test network and your production network would do the trick. Checking for rude behavior on the part of the test network is good, but given that it's "untrusted", quarantining it is better, IMHOP.

My question is - Can SA check for new DHCP servers being added to the network? (We've got a rogue department who install stuff as well as technicians who do!!) Regards, Tobie Fysh
