pfSense is a m0n0wall-derived operating system. It uses Packet Filter, FreeBSD 6.x (or DragonFly BSD when ALTQ and CARP is finished), ALTQ for excellent packet queuing, and an integrated package management system for extending the environment with new features.
Chris Buechler has announced the release of pfSense 2.2.4, a FreeBSD-based firewall solution. The new release mostly includes bug fixes and security updates. The bug fixes include patches to prevent cross-site scripting attacks against the web interface, a fix for a TCP resource exhaustion attack and enhancements to prevent file corruption during unclean shutdowns. Buechler points out that a recent patch to FreeBSD's OpenSSL implementation was not needed as pfSense did not ship the vulnerable version of the OpenSSL software.
