    DHCP Proxy Client

    In regular DHCP client configuration, the client and server are on the same subnet. The client makes a request to the server for an IP address and other configuration items and associates them with the local host interface. This may happen at boot time or at renewal time or at interface initialization. In a DHCP proxy configuration, the client and server are on different subnets. The proxy intercepts the request from the client and mimics the server. It forwards the request from the client to the server and informs the server of the subnet from which the client is requesting an IP address. The server responds with the IP address and other attributes, which are forwarded to the client via the proxy. In a DHCP proxy client, the subscriber manager requests the DHCP server for an IP address and other configurations on behalf of the subscriber. The proxy hides the server details by acting as the server from the view of the subscriber, whereas the actual client uses the IP address and other configuration details. The server notices this proxy agent and communicates to the client like it would communicate with the normal proxy agent in the network.
