NAT in Win 2000

go to www.microsoft.com --> Click on Support and drag to Knowledge Base.

Type in Windows 2000 as the product and do a keyword search on NAT.

You'll find a couple of webcast's (tutorials) and 50 some other articles.

If you only need to share a dialup internet connection with local clients in windows professional, you can do this easily.

From Start/Settings, select Network and Dialup Connections. Right-click on the dialup connection that you wish to share, and select properties. Within the properties of the dialup connection, you click on the Sharing tab and make the selections that you require. Your Win2k prof machine will be a mini-DHCP server (can't resere addresses) to any local clients needing anIP and will act as a gateway and translate local traffic to the internet over the dialup connection.

This isn't proxy server or anything, but it works for many small businesses and home networks.

To run NAT you first need to be running win2k server. If you are using prof. you can share your connection per the previous answer. If you are running server you need to instal RRAS (routing and remote access)
open RRAS expand your server, expand ip routing right click general and click New Routing Protocol...in the dialog box choose Network Address Translation (NAT)click OK
Now under IP routing you will have Network Address Translator rigth click and choose new interface click public interface connected to the internet and then select translate TCP/UDP headers Click oK there is also alot more configuration that can and may need to be done but in any case if you have server that should get you started.....
