Abstract
A server responds to a DHCP request for an IP address by setting a subnet in accordance with whether the client's MAC address is recognized as previously having been authenticated or otherwise associated with a policy. If the client has not been authenticated, the server provides a captive portal to enforce authentication. A routing device positioned in the network between clients and the server controls access to network resources by routing communications from clients in accordance with subnet addressing, where each subnet is associated with a policy.
