NAT configuration

By kwonders ·
Is it possible to configure NAT on a Win2k server that only has a dial-up connection to the Internet as opposed to a constant connection? This server is futher restricted to obtaining it's IP address and DNS info from the ISP automatically. Not possible to get static IP from ISP. Will NAT work under these conditions?

If you server address would change at each connection via dialup, how would you ever find the server even if it could do that? You can use RRAS to do what you want but you would still need a static IP. I would recommend investing in a business class DSL for any remote access. Even terminal services which only passes screen data is slow using dial-up.

Set up the routing services like a bridge. So that your dialup connection will be attached to one network while your server can be bridged to another. It is much easier then dial on demand in NT.

There should be no problem doing this - although if you have a lot of computers sharing the connection it will be pretty slow. Here are the basic setup steps:

1. In Control Panel, double-click Network and Dial-Up Connections.

2. Right-click the connection you want to share, and then click Properties.

3. Click the Sharing tab, and then click to select the Enable Internet Connection Sharing for this connection check box.

4. If the connection you are sharing is a Dial-up connection and you want the connection to dial automatically when another computer on your network attempts to use external resources, click to select the Enable on-demand dialing check box.

Hope this helps!

Theirs no problem with that even your using a dial-up connection and even your using dynamics ip address you can still use a NAT. but you can ask your ISP if the can gave you a static ip I think the will give other option. If you want. But not the option that you have right now..

Use RRAS dial on demand. Dont worry about the dynamic ip, that is attached to your dialup adapter and not the network card.....

Thank you all for your suggestions. I have tried a number of times to get NAT working on my home network. Two boxes, one running W2K server(acts as my domain controller,DHCP server,DNS server), the other is a Quad boot Workstation W98, W2kpro, XP, red hat 8.0). I want to connect my dial-up to my server, get NAT working to share the connection with my workstation utilizing the benifits of NAT (not ICS). I have thus far failed to get either NAT or ICS to function at all. Not sure why. Thought maby a constant connection or a static IP was required by NAT. IF it is not I am back to square one and must look for the problem elsewhere. Will try again over the weekend and get bact to this Question and reward the points to the suggestion that helpsme most. Any other suggestion will be appreciated. Thanks again

Additionaly;
The following is as excerpt from M.S. Knowledge Base article #299801 (How to configure a W2k server as a NAT):
Verify that Transport Control Protocol/Internet Protocol (TCP/IP) and support for your internal and external network adapters is installed during the networking options configuration. (To verify or change settings, right-click My Network Places, click Properties, right-click Local Area Connection, click Properties, click Internet Protocol (TCP/IP), and then click Properties.) Use the following data to configure the TCP/IP address of the network adapter that connects to the internal network:
TCP/IP Address: 192.168.0.1
Subnet Mask: 255.255.255.0
No Default Gateway
Domain Name System (DNS) Server: Provided by your Internet service provider (ISP)
Windows Internet Naming Service (WINS) Server: Provided by your ISP
Use the following data to configure the TCP/IP address of the network adapter that connects to the external network:
TCP/IP Address: Provided by your ISP
Subnet Mask: Provided by your ISP
Default Gateway: Provided by your ISP
DNS Server: Provided by your ISP
WINS Server: Provided by your ISP
This indicates to me that you MUST have static IP info!
Otherwise it would insdicate in some way that you could use automatic IP info supplied by the ISP. But the article does not in any way indicate that.
Am I wrong in my interpretation of the artical? Do you need two nic cards to make NAT work?

When I say static IP info I am refering to the Microsoft instructions for filling out the IP info for the the network adapter that connects to the external network. Sounds to me like they want you to have spicific permanent TCP?IP info.

Thanks for your patience!
