Abstract
In one embodiment, a security gateway receives an IPSec Initiation (IPSec INIT) request from a client. The security gateway may communicate with a AAA server to authenticate the client. After authentication, the security gateway intercepts a URR Discovery request from the client. The security gateway determines registration information for a response to the registration request. The registration information may be information on where the client can locate a D-GANC. A response is generated using the determined information and sent to the client. The response to the discovery request is performed without communicating with a P-GANC. Accordingly, a security gateway is used to authenticate the client and also to respond to the discovery request. This does not require that a P-GANC function be deployed in a network. Thus, cost and processing power may be saved.
