Webfwlog is a flexible web-based analysis and reporting tool for firewall
logs.  It supports log files in standard ipfilter or ipfw format.

With Webfwlog you can design reports to use on your firewall logs in whatever
configuration you desire.  Included are example reports as a starting
point.  You can sort a report with a single click, "drill-down" on the reports
all the way to the packet level, and save your report definitions for later
use. You can also create a link directly to any saved report definition.

Webfwlog requires a web server with PHP support and a MySQL, mariadb or
PostgresSQL database server.
