Written in perl, supports Linux/iptables and OpenBSD?/pfctl. GPLed. Supports authenticating modes against an auth service with a wide variety of backends, including a MySQL? database, PAM, RADIUS, LDAP, and more. Also features a non-authenticating "open mode" that merely requires a user to accept an AUP before they can log in. This project is more or less seeking a new maintainer.
