There is an application called ForceBindIP that allows you to bind certain applications to network connections. It doesn’t work for all applications, but most of them. It is also a bit glitchy in Vista and 7.
Write down your IP Addresses. I use a wired and wireless connection.
-Run -> cmd
Modify your Application shortcut’s target window
-Add forcebindip ipaddress in front of “C:applicationpathexecutable.exe”
