iplist is a list based packet handler which uses the netfilter netlink-queue library (kernel 2.6.14 or later). It filters by IP-address and is optimized for thousands of IP-address ranges.
Netfilter tracker is a tracking tool for iptables logs, similar to Checkpoint(tm) Smartview Tracker. Includes storage in an embedded SQL database and a graphical application (viewer) to access filtered data.
