fwanalog is a shell script that parses and summarizes firewall logfiles. It understands logs from ipf (xBSD, Solaris), OpenBSD 3.x pf, Linux 2.2 ipchains, Linux 2.4 iptables, and a few types of routers and firewalls (Cisco, Checkpoint FW-1, and Watchguard). The excellent log analysis program Analog is used to create the reports.
