reject_unknown_client
     Reject the request when the client IP address has no PTR (address 
to name) record in the DNS, or when the PTR record does not have a 
matching A (name to address) record. The unknown_client_reject_code 
parameter specifies the response code to rejected requests (default: 450).

takze problem je v 1X8.1X7.19X.2
