4.7 . Dynamic Blacklist Rules
The dynamic blacklist rules are the blocking rules added by the SIP Firewall deep packet
inspection engine to block the traffic from attacker IP addresses for the blocking duration
configured in the rules category, on detecting the attack.
The dynamic blacklist rules will allow the administrator to see the dynamic blacklist rules
currently configured on the device at any instant. In case if the administrator wants to
override and allow the traffic from particular blacklisted IP, he can delete the rule from the
dynamic blacklist rules page.
