10.2.6. Exempted Connections Chapter 10. Traffic Management 10.2.5. Multiple Triggered Actions When a rule is triggered then NetDefendOS will perform the associated rule Actions that match the condition that has occured. If more than one Action matches the condition then those matching Actions are applied in the order they appear in the user interface. If several Actions that have the same combination of Type and Grouping (see above for the definition of these terms) are triggered at the same time, only the Action with the highest threshold value will be logged 10.2.6. Exempted Connections It should be noted that some Advanced Settings known as BeforeRules settings can exempt certain types of connections for remote management from examination by the NetDefendOS rule set. These settings will also exempt the connections from Threshold Rules. 10.2.7. Threshold Rules and ZoneDefense Threshold Rules are used in the D-Link ZoneDefense feature to block the source of excessive connection attmepts from internal hosts. For more information on this refer to Chapter 12, ZoneDefense. 10.2.8. Threshold Rule Blacklisting If the Protect option is used, Threshold Rules can be configured so that the source that triggered the rule, is added automatically to a Blacklist of IP addresses or networks. If several Protect Actions with blacklisting enabled are triggered at the same time, only the first triggered blacklisting Action will be executed by NetDefendOS. A host based Action with blacklisting enabled will blacklist a single host when triggered. A network based action with blacklisting enabled will blacklist the source network associated with the rule. If the Threshold Rule is linked to a service then it is possible to block only that service. When Blacklisting is chosen, then the administrator can elect that existing connections from the triggering source can be left unaffected or they can be dropped. The length of time, in seconds, for which the source is blacklisted can also be set. This option is discussed further in Section 6.7, "Blacklisting Hosts and Networks". 280
