How to use a public IP address when all others are non-routable?

I added a new Windows 2003 R2 server into an existing domain consisting of just one Windows 2000 SP4 server and a few XP clients.

The existing 2000 domain uses private IP addresses of the 192.168.1.xxx subnet. I had to give the new 2003 server one of them to join it to the domain. But now I want to change it to a public IP address so it can be a web server. But I still want it to be part of the domain and be able to share files and printing. And I may make it a backup domain controller.

The public IP address is part of a contiguous block of 8 that we bought from our ISP. One of the others is used in the DSL router. I think the router is what hands out the private IP addresses to the domain PCs. I put some details about this at the bottom.

Can I accomplish my goal (the posted question)? If I have to, I can give the other server, the 2000 box, a public IP address that is in the same subnet as the DSL router and the new 2003 box.

SOME DETAILS ABOUT THE ROUTER:
* Our ISP is Qwest. The 2000 server is connected to a Qwest 2-Wire DSL router.
* Under “Current Settings” it is set up with “Public Proxied Subnet (NAT/Routed).”
* Also under router’s “Current Settings” is “Private Network” and in that configuration area the router IP address is assigned to 192.168.1.1.
* In another configuration area DHCP is enabled. All the XP clients get dynamic IP addresses and they are always 192.168.1.xxx.
