A client of ours has asked that we configure a single Windows 2012 DHCP server to act as a multihomed DHCP server for a trusted as well as an untrusted public network segment. From looking at documentation I can see it's not too hard to set up a second scope, and bind that scope to a second NIC with a statically assigned IP on the untrusted network.
The problem is, this server does not have two NICs. Could this be made to work if we added a second static IP in the untrusted network to the only NIC on the server?
