This have to be done by the first proxy in the chain. This because to perform the ident lookup the original IP address and port numbers need to be known, but X-F-F header only records the IP address.. I'd suggest you use client -> Squid(auth) -> DG(filter) -> Squid(cache) -> Firewall. Regards Henrik
