How to control the open connections to some IP's for a running program by using c#

I need to monitor and control a program running on my machine(utorrent). This program establish connections to other PCs on the internet. I can know the IPs which he is connecting to from a list on it I need to control these connections,limit them or close them and control the bandwidth they are using.

How can i get all the connected IP's to utorrent and control them all by certain conditions i can put later using C# 2.0?

• Not sure how helpful it is, but try looking at WinPcap develpment tools: http://www.winpcap.org/devel.htm It's a c library, not C#, but maybe it'll help you.
