bitcomet embedded in Opera


I am using utorrent and Opera (embedded bitcomet) for my downloads. My listen port worked for a while, then it used to get blocked.

I found on the forum the tutorial on hiw to configure utorrent; by that time i had already set my policy for it as “trusted application”

But how can i do this for Bitcomet/Opera? I would not make opera a trusted application (it does much more things than a torrent). Also i cannot limit it to a narrow torrent policy. And bitcomet does not appear as a separate program in the opera folder.

Can anyone help?
