We have several distributed RADIUS servers that have been using the robust-proxy-accounting model to centrally log accounting information into a mysql database. Now we want to use that info for coa/disconnects. In the coa virtual server example, the RADIUS server gets a coa packet, then looks up the required data to form the coa packet to send to the NAS. Is there a way to have the centralized accounting server receive the disconnect packet, lookup the info in that mysql instance, then proxy that to the right source RADIUS server, so that server can send the coa (or disconnect) to the NAS ? Some vendors either only allow one or two RADIUS servers and those servers must be used for auth/accounting. We really don't want that central accounting server performing auth for everything, thus why we want to proxy it locally to the right instance for the NAS. So can something like that work or do we need to come up with plan B ?
