If all these addresses refer to different NICs on your system, then
there is a way to accomplish that.
Libnet provides an interface to work on the system's linklevel.
That means you can specifiy which device to use to send the packet.
The drawback is that you have to build your packet by hand from
ground up. But libnet helps you out here, it makes it
reasonably easy to construct ip,tcp and ethernetpackets.
You can wrap this up in a function for your convinience.
But your code depends on libnet then unless you digg into
libnet's code and see how the guys have done it.

Refer to the libnet documentation to learn more.
You might want to use an older version as it changed much
since i last looked at it.
