Send Accounting from any point in configuration

Hi, I want to send RADIUS Accounting Messages to another RADIUS Server, depending on some contents of a Packet. 'a Packet' in this context might be an Access or an Accounting Packet. The intended Flow: Packet comes in ... - for Access type, check if user might be authenticated - if OK, try to decide to send an Accounting packet to a Server on some attributes (in my case, VSA from downstream RADIUS Proxy Server) - (possibly) don't care about the answer - for Access type: accept/reject to Client - for Accounting type: ACK to Client As far as I understood, the proxy module does - (only) proxy based on realm - in proxy module, normal local Logfiles won't be used What would be a good solution for this? Thanks Stefan
