The handbook states that pf is available through KAME in 4.11 and from my reading Kame is build into the system. How do you enable pf and altq on 4.x then. I have had trouble finding any how-to's on this since everything for pf points to 5.x. I just can't justify running 5.x on a production firewall though unless the performance greatly improves over 5.3. Chris
