Using Mul;tiple IP's in W2K Server

[jckurtz]

We have a group of 5 static IP addresses assiged to us by our ISP. We would like to use these IP addresses for DNS and web hosting for our small company. I have a separate NIC for these addresses. I can ping all five addresses through the internet, but I can only access one website, the website using the first of the 5 addresses. Can anyone suggest what I might be doing wrong?

Describe your network in more detail. What are your servers running? What type of server are you using to host kyour web site. Are you using a DMZ? And so on!

If you are using IIS. Check the properties of the web site and check that the 5 IP address are bound to it.

Thanks for your help. I really apprciate it.

Perhaps a more detailed definition of the problem is in order.

We are running W2K Server. We have two nics installed. One for a private network which is working fine, and one for a public network we are trying to implement. We are using DSL through a DSL modem which is connected to the public nic. Our ISP has assigned us five static IP addresses which we have entered into the public nic.

We are using IIS to serve the websites and we have setup two websites for testing purposes. One using the IP address of xxx.xxx.xxx.146 which is the first usable address of our assigned block. The second website is using xxx.xxx.xxx.149.

Using Internet Explorer through the private network which has its own, separate DSL access to the internet, I can use

http://xxx.xxx.xxx.146/

and the website assigned to that IP Address displays properly. If I try using

http://xxx.xxx.xxx.149/

I receive a "server not found" message. If I swap the IP address bindings of the two websites, restart IIS and redo the above test, I get the second website which is now assigned to xxx.xxx.xxx.146
and still get the "server not found" error on xxx.xxx.xxx.149 which shows that it's the inability to access the xxx.xxx.xxx.149 or any of the other IP Addresses other than xxx.xxx.xxx.146 is the problem.

Using the internet connection on the public network, I can ping all 5 IP addresses. sucessfully.

We encountered this same problem with NT4 Server, but it could be fixed by adding an entry to the registry for ARP. If you have any ideas, I sure would appreciate hearing them.

Again thanks for all your help. I just discovered that the problem is with the ISP and not the operating system. Hopefully we will get this straightened out.

Yes, I agree. But the issue was in trying to duplicate this problem and try to resolve it. I still find it strange that the unm/pwd get passed to the serving computer for resolution ... just having a tough time trying to figure out why its this way.
