Install [https://github.com/ntop/bro-pf\_ring](https://github.com/ntop/bro-pf_ring) in general for best results. Use interface=pf\_ring::p1p1,p1p2 ---

Hi Justin and Raphael, Very good point and very interesting issue. Some questions…. What does exactly do bro-pf\_ring? What does “best results” mean? Is it mandatory to use bro + pf\_ring? If not what features are added?
