Using NAT with PPPoE

[korpse]

This is a pretty technical question, but I hope someone can help me.

OK, here is my situation:

I have a Windows 2000 Server with 2 network cards (one for the internal network and one for the internet). I need this to act as a gateway using Network Address Translation. The problem is that I have Earthlink DSL which uses PPPoE to make its connection through the NIC that is connected to the DSL modem. When I got to set up NAT in Routing and Remote Access, it does not recognize the PPPoE connection as an interface (Im guessing because it is a virtual connection).
Does anyone know if what I want to do is possible? I've set up NAT before when my external NIC was my actual internet connection (not PPPoE), and it was pretty easy.

Thanks in advance.

I would recommend that you get a dsl router and NAT it at that point. DLS routers are cheap($75+) and most of them support PPoE

have you tried configuring the server with ICS instead of going through routing and remote access? Sometimes that works....Q273587 in technet has some information too that may help.

Thanks for the help guys. I'm not a big fan of ICS (it's really insecure and from a networking viewpoint its pretty crappy), but Weazel you are absolutley right that it would work that way.
I wound up taking tha 4NiK8R's advice and getting a cheap Dlink firewall/router that supports PPPoE and throwing it between the server and the dsl modem. Then I set up NAT the way I wanted on the server and it works like a charm (I know I could have used NAT right through the router but I need the server to act as a sniffer).
Thanks again for your input guys!
