Sometime around mid-2009 Sourcefire made rule changes that require preprocessor updates. I can't seem to find that announcement now. Running -current rules on the 4.5 package broke snort for me (without disabling a handful of pre-processors.) I ended up building an (unsupported) 2.8.4.1 package from -current ports which has worked for me since August. I believe snortsam has been referenced to go from IDS -> IPS, but I've not used it. -Steve S.
