Hello, Ralf, thanks so much for your answer.
Oh, well, I discovered what was the problem. It was something REALLy
silly: While testing both computers, I kept them connected to the hub
at the same time. My Linux box was getting confused because WinXP
still had DHCP running. Oh, well, so many hours testing and testing...
=)
Now that I can access the internet with my Linux box, I am trying to
make the computers in the local network to access the outside world. I
will look out for some tutorials about masquerading now. It's being so
painful to get things to work!!
Again, thank you so much!
