Monitor Non-standard Bittorrent Traffic

Monitor Non-standard Bittorrent Traffic

My Cisco router 1841 will detect Bittorrent traffic correctly using NBAR whether or not it uses the standard 6881-6889 port. However, when viewing the application report in Netflow Analyzer 4, pretty much all bittorrent traffic goes under the TCP_App category, very few actually went to the bittorrent category. Is there anything I can do or configure so that it will capture non-standard bittorrent traffic to the right category?
