Wow the guys from PFSense.org are going to be running a Tutorial in Poland this October. How exciting.
For those who have not had a chance to use the awsome PFSense it is an open source firewall solution based upon Free BSD and PF (Packet Filter software). The feature list is longer than my arm and although it can be a bit picky when it comes to hardware drivers (It is Free BSD and not Linux ) it is just a wow product that I cannot recommend enough.
Next time your looking for a firewall before you pick up the Vyatta, Moonwall, Untagle etc disk try PFSense first.
Oh and If I can I want to meet you all in Warsaw on October the 18th for the PFSense 2.1 launch party and tutorial.
