Use vista home premium as router

How can I use Vista home premium to route local lan traffic?

That is, how can I arrange things so that local lan traffic aimed at
an external address on my Vista Home Premium OS gets routed to another
subnet.

The built in adaptors are:
Wireless: Intel (R) PRO/Wireless 3945ABG Network Connection
Ethernet: Realtek RTL810 Family PCI-E-Fast Ethernet NIC (NDIS 6.0)

I'd like to get two external IPs up on the wireless adaptor if
possible.

Must I have two Adaptors to maintain two external addresses or can I
get two external addresses on the built in adaptors, possibly with
third party software?

This post may help.

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.
