NAT on Win 2000 Advanced Server

My cable modem provider uses DHCP addresses and allows me to have 2 concurrent connections. I would like to setup NAT on my 2000 Server and have more. Can anyone point me to a site that give step by step instructions on how to install/configure NAT?

Routing and Remote Access is what you need to use. Then under IP Routing add a new routing protocol using NAT.
 
Thanks for the replies. I have used the wizard and at the end it tells me that it can't find a network adapter. Even though I have network connectivity to the internet. I will look further but would appreciate any help.

It should give you a choice of the two adapters to use for the internet connection and which to use for the internal network.
 
I have not installed SP1 on the server. I added a second card and got the NAT to install. I just don't know how to configure it. Both NICs should be set to DHCP in the card properties? Correct?

I am not sure if I am setting up NAT correctly. What should the settings be?

Thanks for all the responses.

First thing, your NIC's should not have DHCP enabled in the TCP/IP properties. This is going to be your gateway server to the Internet. If the DHCP address lease expires and it gets another address, then you will spend about a couple of days just trying to figure out why your clients cannot browse the Internet. Make the IP address a static IP address on your LAN segment.

Install SP1 on your machine. SP1 address some critical issues with RRAS. Also, make sure that you have the latest drivers for your NIC's.
 
Here is how I set this up last night. I use DHCP on my LAN, but that isnt a requirement for you.
1. Install 2 Nics on the server (preferably 2 DIFFERENT brands, it will make IDing them easier)
2. Install Client for MSN, TCPIP, And File/Printer Sharing on both NICS
3. Unbind File and Print sharing on the Card you are going to plug your cable modem into (this is the WAN and u dont want FPS on that)
4. go to TCPIP...advanced...WINS...and enble netios over TCP (ONLY DO THIS FOR THE LAN CARD...not the WAN card)

Now decide if u want DHCP on the LAN or not...lets assume you dont. Assign 192.168.0.1 as the IP for the internal nic and a 255.255.255.0 for the sub. You will also need the DNS addy of your ISP and enter that there. The WAN card leave alone, since it will be assigned an IP through DHCP from your ISP

On your clinets confige the nic cards the same way you did the internal (LAN) card on hte server.
For IP use 192.168.0.2 and so on. For gateway you want 192.168.0.1

Now, on the server install Routing and Remote Access.
Go to the RRAS manager. Right click on Server Status and click add server.
It will ask which one..choose "this computer"
Wait for the server to be added...then right click on the server name and choose "configure and enable RRAS"
A wizard will pop up and ask you some questions.

I am not at my machine right now..so things are a bit fuzzy..bear with me.
It will ask what type of server u want..say internet connection sharing
Then it will ask if you want ISC or NAT based...choose NAT

Make sure that the RRAS service is started and set for auto start.

Thats all there is to it. I wish I was at the mchine so I could make sure that I did all that in order, but it should be enough to get you on the right track


 
blstriker..nice find, but that is ICS (internet connection sharing) not RRAS. RRAS is a much more effective way to route traffic. It gives you much more control ever ports, etc....
