using specific internet connection for utorrent

[parasyte]

i have 2 internet connection, thus this is what i tried to do

firstly, PC is connected to internet connection A directly via ethernet, obtaining a wan ip.

PC is also connected to internet connection B via a router wirelessly, thus obtaining a lan ip.

i set the metric for the wireless to 15 so that the PC would by default choose to use its connection.

and also set in utorrent advance settings the net.bind_ip and net.outgoing_ip to the wan ip of connection A.

without running utorrent, connection utilised via connection B. (confirm using tracert, and also when surfing to a ipchecking site like whatismyip.com does reflects the wan ip of internet connection B.

problem is when i on utorrent and start the torrents.

somehow, the connection will change back to connection A. (confirm using tracert, and also when surfing to a ipchecking site like whatismyip.com when torrent is running, it now reflects the wan ip of internet connection A).

kindly advise how can i make it so that my general internet connectivity will be via connection B and only utorrent is utilising connection A.

Thanks

Windows breaks any attempt to restrict to a single connection.

kindly elaborate more on what you mean by "Windows breaks any attempt to restrict to a single connection."

thanks

Windows likes to ignore the bound NIC and use a different one anyway.
