A personalized firewall or other network gateway is provided by a method of matching a data packet to a rule in a network gateway having a rule base. One or more identification values are determined (302) on the basis of the data packet and property value(s) associated with said one or more identification values are queried (304) and received from a property server. The property value(s) describe for example allowed connections and services for an entity associated with the identification value(s). The property value(s) are compared (306) to at least one rule in the rule base, said at least one rule comprising property value(s) and an action, and the action defined in said at least one rule is taken (310), if said property value(s) of the rule match corresponding property value(s) associated with said one or more identification values. <IMAGE> <IMAGE>
