[Bro] Toggling traffic direction in reports/logs?

First off, I hope everyone had (is having) a happy holiday season.

I've finally got the daily Bro reporting mechanism working and  
sending out emails as I expected. However, after letting it run for a  
few days, I'm starting to notice something that's a little unusual.  
The Bytes In/Bytes Out pair as well as the Local Host/Remote Host  
pairs seem to be opposite.

For example, it will say something like:

Remote    Conn.
      Local Host               Remote Host           Bytes       
Bytes     Count
-----------------------  -----------------------  ---------   
---------  -------
some.externalhost.com	 my.internalhost.com        1562 K     142902   

This is the exact opposite of what is the actual traffic pattern. Is  
there a way that I can tell Bro that my /28 subnet is "local" and  
everything else is "remote"? I don't seem to see anything like that  
in the configuration files.

Thanks so much!
