How to configure Bro to detect UDP port 53

Hi all,

I am a new Bro user, I did few experiments to read the same DNS trace file via Bro online version and Bro from my personal PC. The version number is 2.3.1.

I got some interesting results. the online version checks UDP port 53 5353 and 5355
id.resp_p proto trans_id query
5353 UDP

But, the one on my PC only checks port 5353 and 5355.

Is this a configuration issue? And is there a way that I can configure my Bro to check port 53?

Thanks

Steven
