Assuming that you'll use port 64000 - 64100 for multiple clients

1) Set up the following new Protocols:

Name: BitTorrent (Inbound)
Ports: TCP - 64000 to 64100 Inbound
Secondary connection: TCP 64000 - 64100 Outbound

Name: BitTorrent (Outbound)
Ports: TCP - 64000 to 64100 Outbound
Secondary connection: TCP 64000 - 64100 Inbound

Name BitTorrent (UDP)
Ports: 64000 to 64100 Send Receive
Secondary connection: 64100 to 64100 Send Receive

You can add each of these to the same Access Rule.

Create another new Protocol on a per-client basis:

Name: BitTorrent (Server - <Client Name>)
Ports: Create a TCP Inbound port range somewhere between 64000 and 64100 (e.g. 64000 to 64010)

Create
a Non-Web Server Protocol Publishing Rule per BitTorrent client (client
machines must have static IP or have DHCP reservations). These rules
are the same thing as SOHO router's "port forwarding":

Name: What ever you want, be descriptive as to what the client using this rule is
Server IP: The client running BitTorrent
Listen from: External (aka The Internet)

Edit
the above Server Publishing rule and go to the To tab. Make sure the
radio box "Requests appear to come from the original client" is ticked.

Go to Configuration -> General -> Define Firewall Client Settings -> Application Settings tab

Create two New Applications:

Application: [Executable name without file extension, e.g. utorrent]
Key: RemoteBindUdpPorts
Value: 64000-64100

Application: [Executable name without file extension, e.g. utorrent]
Key: ServerBindTcpPorts
Value: 64000-64100

Save all of the above changes and commit them to the ISA Server.

Open utorrent, go to Options -> Preferences -> Connection, set the/a port that your Server Publishing Rule is using.

Under Advanced, go to net.outgoing_port and set it between 64000 and 64100.
