Implements downloading of IP address blacklists and implementing them as IPSets. A separate IPSet is used for each blacklist; this simplifies handling of overlaps between different lists. Traffic to or from the red0/ppp0 interface is checked against the IPSets. The check is placed before the IPS check as the IPSet check is much lighter on CPU use which means that overall CPU use is reduced.
The available lists are defined in a separate file. A WUI page allows the desired lists to be enabled and the interval between checks for updates to be defined. A minimum update check interval is defined for each blacklist in the definition file.
Optionally, an automatically updating blacklist can be enabled. This adds addresses to an IPSet if the rate of packets dropped by the default red0/ppp0 input policy exceeds a user defined threshold. The addresses are kept in the IPSet until a user defined period without packets from the blocked address has passed.
