Abstract
A method for providing leased network addresses for a host from a server executing on a server device is disclosed. A first request for a leased network address from the host, relayed by an intermediate device, is received. The intermediate device filters communications between the host and the server device. A response is generated for the host, by the server, which offers a leased network address for a particular period of time and includes a network address of the intermediate device. The network address of the intermediate device is provided in a portion of the response normally designated for indicating a network address of the server. By providing the address of the intermediate device in the portion of the response designated for the server address, the server causes the client to send renewal requests to the intermediate device so that a relay process on the intermediate device can properly operate on the request, without modifying the client process.
