You are not specifiying which interface to add to, and it doesn't change
anything since we already have a default gateway on ethernet/netgear
(btw, we ignore wintv/hauppauge, this is just a tv card, unrelated!!)

Someone said (can't remember who now) that we only need one
default gateway, is that true. Does it mean that the Bluetooth
gateway will know to route the network through the Ethernet
adapter. My problem really, is that I am guessing, I know a bit about
networks, but obviously, not all that is required.

Another question has popped up as well (again I don't remember
who it was), that in Windows XP (as opposed to Windows 2000)
there is a Bridge Connections option which flattens two subnets
into one. Now the question (or questions) is this, since Windows
2000 doesn't have this option, and since this option was added
to XP, can we conclude from that that ICS will not work when
we have two internal subnets, where computer 3 needs to reach
computer 1 in order to see the internet, but it has to first reach
computer 2 before it can see computer 3

3 ----> 2 -------> 1 = internet

btw, my computer 3 is working fine, because if I transfer the internet
modem to computer 2 , it does find the internet. I.e. , it is this extra
hop which seems to be the problem.

Now, since I am not a network man, can I ask you if traditionaly,
i.e. if we don't have an ICS setup, but real static ip's, and computer 2
is like above, i.e. bluetooth+ethernet, and computer 3 need to access
computer1, do I need a default gateway on both adapters on
computer2 , or just one.
