NAT over Windows NT4.0

Your server has to work as a proxy server to allow users to use it for a shared internet access.
From your description, I'm a little confused though--to what are you connecting with your second NIC? If you're connecting to a router going to an ISP,I would check with the ISP to see if they have a firewall preventing access to the outside world. If so, THEY'LL need to put in a NAT for you and alias your subnet into their table. If not, you'll have to have the IP address of your outside NIC published in the internet DNS sytem, and your internal subnet on the other NIC.

Thanks a lot for your quick response.
I think I got your point! The situation is as follows: the outside adapter is coneccted to another local network. This local Network already have access to the Internet. this Network is having access to the internet from a Cisco 2611 router connected to it. So I now understand that I need to add a route command on the router, right ?? What else do I need to add on the server?

You don't have to go through a proxy server I don't believe (we have the same setup here but don't have to use a proxy). We set ours up using both netbuei and tcp/ip protocols. Also, with ip addresses assigned to each person. If the local lan youare going through has a firewall, it may not be allowing you to get around it either. We use a VPN client to get around the local to access our company server (Cisco is what we are using for windows9x machines and altiga for windowsNT machines). Are you able to access local sites such as yahoo and msn, or no sites at all?

It's fine now. I don't think that basic W.NT really does NATing but it could route two or more Networks (depending on how many NICs) that have the same subnet mask. Example 192.168.4.x and 192.168.5.x both with subnetmask 255.255.255.0

NATing is usually done between totally different Networks.

The solution to my previous problem was to add a route statement on the router accessed by the outside NIC of the NT server.

Now I'm wondering if I can authenticate users on the in-side of the NTserver to access the Internet. They can now but they're not being monitored and controled. Something like a proxy server. But can we do it without the proxy server ?
