@Plecto:
Im not asking for a network class, Im just wondering what abilities PFsense has to my advandidge? And if someone could explain that in "english" I would be very glad.
We have no idea what features you want and our feature list is rather long. If you can't understand what's written in plain english at http://pfsense.com/index.php?id=26 then I'm not sure how much more detail anyone else can go into.
Here's the simplest possible thing I can tell you (and if it sounds familiar, it should, it's on the front page of the pfsense website)

pfSense is a open source firewall derived from the m0n0wall operating system platform with radically different goals such as using Packet Filter, FreeBSD 6.X (or DragonFly BSD when ALTQ and CARP is finished) ALTQ for excellent packet queueing and finally an integrated package management system for extending the environment with new features.
