Its a combination of eth0 and eth1, so that for example you can get ethereal to listen on both interfaces by selecting sit0.
Thanks Rick, will give that a whirl when I have sorted out FC2 problems. I now have the ethernet card working but I had to set it up as eth1. I have also a sit0 interface before the eth1 in the list. Do you know what that is?
