Use vista home premium as router

Hi
No Network card, wire or wireless, can have two addresses Internal, or
External.
External Address is an Internet address that is given to you by the ISP.
There is No use of two External addresses on one computer even if you do
have two Network cards.
Two External addresses from the same ISP can be on two separate computers
connecting each one independently to the Internet (A risky practice to begin
with).
If you have two independent External; IP from two different ISPs than the
solution is to get a Dual WAN Router.
Otherwise, explain in a functional terms what is your actual Goal.
