A method ( 400, 610 ) for handling information about packet data connections arriving at a security gateway element, in order to have in a connection data structure information about packet data connections in accordance with current screening information is presented. In the method, data packet header information about packet data connections in accordance with first screening information is stored ( 401 ) in said connection data structure, and updated screening information, said updated screening information forming either by itself or in connection with said first screening information second screening information, is being received ( 402 ). After receiving said updated screening information, entries of said connection data structure are compared ( 403 ) to said second screening information, resulting in a classification of said entries as entries representing packet data connections in accordance with said second screening information and as entries representing packet data connections in conflict with said second screening information. Corresponding security gateway element, management system, computer program and connection data structures are also presented.
