pfSense® includes most of all the features in expensive commercial firewalls, and more in many cases. The following is a list of features currently available in the pfSense® software 2.1 release. All of these things are possible in the web interface, without touching anything at the command line.
In addition to features, this page also includes all limitations of the system of which we are aware. From our experience and the contributed experiences of thousands of our users, we understand very well what the software can and cannot do. Every software package has limitations. Where we differ from most is that we clearly communicate them. We also welcome people to contribute in helping us eliminate these limitations. Many of the listed limitations are common to numerous open source and commercial firewalls. 2.1 limitations already fixed in the code that will become the next major release will be noted.
