torrent flux is just a front end for BitTornado, simple as !
I am unsure weather this issue is really a dodgy underhand VM DPI style tactic of weather it is a real technical issue. I use windows vista and i have patched the limited half open TCP Ports option which dosnt solve the issue. It would be interesting to know how far these HTTP requests are getting into VM's network before they start getting lost. I wonder if its at UBR level or at the CMTS. DPI stuff is most likely to happen nearer the CMTS as far as i can imagine with the practicalities of installing the kit in the UBR's and all.
Anyone care to enligten me ? i would run some tests but im at work at the moment on a crappy BT 6meg ADSL line
