That=B4s exactly the ways I imagined to do the job. I have been trying to configure Virtual PC to do it, still unsucessful. Binding to the IP, I=B4ve already did that, but in my understanding, I can just "hear" what=B4s going on the wire right? I can=B4t bind and manipulate the data being sent or received on that IP, am I wrong? Anyway, thanks for your ideas. Having another person thinking that way makes me feel like I am on the right path.
