Dears

I want to use packet filtering framework supported by Bro. It filters based on static IP address. But in my case, I want the filter to read IP address from from a dynamic file (a file that is updated from another bro instance).  
How to do that?  
My bro version: 2.3 running on ubuntu platform.

Thanks in Advance
