Multiple IP's over ADSL with PPPoE

I need to setup Windows 2k3 as an edge device between the internet and a
private network using an ADSL BRIDGE as opposed to a router. The Windows
box is to be the router.

Until now I have been able to avoid PPPoE, which I find to be an annoying
technology. When setting up routers with more than one IP I have been able
to just overload the outside NIC/interface with all the public IP's and NAT
them in whatever way is necessary. This configuration, mind you, is how it
has been done when assigned a bunch of IP's vs. a routable block.

With PPPoE, however, I can only assign one IP address to the configuration.
What's worse is that Windows apparently supports only one active PPPoE
connection at a time. So my question is, how do I get this Win 2k3 machine
to be the network edge device and route/NAT all my public IP's to the
internal network?

1. Get rid of PPPoE (even if it means getting rid of the ISP)
2. Get rid of the DSL Bridge
3. Replace the DSL Bridge with a standard DSL modem (has no IP# at all, does
not "route", does not NAT, does not "bridge)
4. Assign all the ISP granted IP#s to the external NIC of the Windows NAT
box. Do whatever NAT functions you need to do from that point.

This is the only recommendation I will make for this situation. You can try
other methods if you wish, but I will firmly stand by this method
only,....unless you ditch Cable/DSL and go with a T1 or similar technology.
