Lokiwall is a firewall script for Linux. In addition to the standard function of easily limiting network traffic, it features dual routing (using two Internet connections simultaniously), connection fail-over, load balancing, traffic control, advanced masquerading, advanced DNAT, and advanced marking (to direct specific traffic to a certain interface). The advanced features require some kernel patches. The standard features will work on a default Linux system with iptables and iproute2.
rpfcd (Remote packet filter control daemon) allows remote control and monitoring of OpenBSD's packet filter. It communicates with clients using the RPFC protocol running on top of SSL. The protocol is designed to be relatively forgiving and easy to use. Its goal is to provide a common framework for pf control and monitoring. Instead of running pfctl/tcpdump/pflogd, writing ad-hoc parsing scripts, and sending the results by mail, rpfcd will provide the same and much more via a transparent server-client interface. Together with a decent CLI/GUI client, pf firewall monitoring becomes rather easy. This is especially interesting if you have several pf firewalls to control and monitor.
