Application bit-internal cannot be allowed.

How can I allow application bit-internal in my policy? This application is blocked by last rule (explicity block rule). I didn't see application bit-internal in my Object->application database and I can't use it in policy. We have PANOS 4.0.8 and application update 289-1268.

it Lists out the Application Depenencies, and "bit-internal" is dependant on "Web-browsing".

Is that part of the last rule"?

I read this document. But I want to know why I can not choose the applications 'bit-internal' when creating policy. Even if the application 'web-browsing' is allowed my traffic is still blocked  'bit-internal'.

Hmm... "bit-internal" isnt available on http://apps.paloaltonetworks.com/applipedia/ either (which I suppose contains latest app-id db?)

Edit: Did it perhaps get merged into "bittorrent" or some other appid? Because if you look at the dependecy document "bit-internal" is just before "bittorrent" comparing to "gnutella-internal" which is next to "gnutella".

Yes. On device I have latest app-id database, too. There is no 'bit-internal' in Objects -> application, but ... when traffic is analyzed logs show application 'bit-internal'.

internal apps:

This app is reported as bittorrent on the UI. This is what is going to happen for bittorrent:

1.       UDP sessions comes
2.      App id detects that it is bit-internal. It gets reported as bittorrent on UI
3.      App becomes bit-internal
4.      Bit-internal decoder runs
5.      It predicts TCP session
6.      It sets the app to bittorrent
7.      The session gets blocked if the action is deny for bittorrent
8.      TCP session arrives, and it becomes bittorrent, as expected
