in short, you have to tell the machine which one are the default gateway ( going to the Internet), and if you have networks going to another network card they have to be defined, google windows routing.
It's not that hard to do.
routing can be tricky when you want redundancy, but in your case, static routing will do it.
Thanks for the info i will give it a go, I just hope the software that I need to use will let me.
