for packet routing puzzle lovers--aka, routing problem

Heh. From what I know, internet sharing on a windows box is not the same as
packet forwarding. It is actually NATing your packets - do a tcpdump to
verify. This would mean that the box behind the w2k machine could get out
fine, but no one from the other side could reach it directly. If I
remember correctly, there used to be "forward between interfaces" or such
option on NT, perhaps W2k has the same. I checked on my box here and
couldn't find it, but that could be because it only has 1 interface.
