send radius response without request

Is it possible to have FreeRADIUS send a radius response without first receiving a request, provided I can feed it the same information the request would have? OR Is it possible for FreeRADIUS to see the request come from one host and have the response go to another? Jake Sallee Godfather Of Bandwidth Network Engineer Fone: 254-295-4658 Phax: 254-295-4221
