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

[Guest quietstorm]

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.

NAT does this. You need to assign a static NAT address in the router to your

server.

It's not a great idea security-wise.

Hi quietstorm

Issue is all about your modem/router. Assuming that you have only 1 IP,

what you can do is port-forwarding. Simply forward port 80 to inside

webserver. You can find how-to in following link for your router (choose

model)
