My go to firewall when one is needed. No muss or fuss when compared to a Cisco, Juniper or other less worth while competitors... The stability longevity and overall security of these systems (when you know what your doing) is second to none. Every system update adds another fix or feature with no empty mess in between. Every iteration makes things more and more useful and simple for the most part! Hard to get any better QoS control than the traffic shaping tab in PFS. Will run on just about anything, and if you have a gig card n it, game over you just got a firewall that is unbeatable, and unless you break it yourself, hardware failure is going to be your only down time!
