Gibraltar Firewall 2.3 has been released. From the changelog: "This is a feature release with two major new features now being fully supported by the web interface: briding (a.k.a. as transparent firewalling) and traffic shaping. Both can be enabled with the respective modules in the web interface. Other changes in the web interface include a quick configuration save link, new service definitions that can now span different protocols (e.g. an IPSec service that include UDP, ESP and AH), the possibility to configure an email relay (e.g. a smart host by the ISP), and some enhancements when integrating a hard disk drive for /var."
