torrent

Hi,
I'm trying to get uTorrent 2.0.4 to work in a DMZ machine, protected by a ISA Server 2006. I've opened 1 inbound port (via publishing) and opened all the higher ports for that specific machine that runs uTorrent on my DMZ, and it's working almost fine.
The problem is that I keep getting packets dropped with 0xc0040017 FWX_E_TCP_NOT_SYN_PACKET_DROPPED. Is there any way to disable this via registry? Is there any way around this?
The download speed fluctuates a lot, and when I starts hitting the upper limit that I've defined in uTorrent, the errors start poping up a lot, and the download speed goes way down, and the process repeats on and on
Tks
Edit
My outbound rules are:

Port Range: TCP 10000-65535 Outbound
Port Range: UDP 10000-65535 Send

Edit
It's probably a bug handling requests from Windows 7. When I installed the uTorrent on a XP machine, the problem went away

I'm running ISA 2006 with PPTP VPN for my AD-controlled network. DHCP is located on the ISA server itself and authentication is done by RADIUS (NPS) located on the DC. Right now my VPN clients can connect, access local DNS, and can ping ISA, the DC, and other clients. Here's where it gets weird… >>> More

I know about bittorrent but have never used it since it tends to be mostly used for illegal download of movies and software. Typically whenever I see a legitimate use for it (Linux distros) there is also a regular download option so I haven't had the need for a client until today. There is a large… >>> More
