internet connection through local subnet

I would like to set up a windows 2000 server with 2 nics so that the subnet attached to nic 1 could access the internet connection of the subnet attached to nic 2.
I only need access to the internet connection, but NOT to the nic 2 subnet.
I presume that NAT might be a good idea but would like more information on how to set this up correctly.

Answer Wiki:
Don't know how many PC's are involved, but suspect you would be better using proxy rather than NAT, there are a number of proxy servers for WIN2k including some freeware. Will be a lot easier to set up and maintain than a NAT system if you have more than a very small number of PC,s. Also more secure if you don't want access between the two subnets.

Yes, Win2k automatically routes between local interfaces on different subnets. If you’re not using the server for something else you could always use IP filters to limit it to certain traffic.
I suspect the solution you are looking for is called Internet Connection Sharing by microsoft. They designed ICS specifically for a home situation where one system is on the internet and you want other systems to use the ICS system as their gateway to the internet. ICS is very limited in what it can do but your description seems to be a good match.
Before implementing this solution make sure the internet gateway system is hardened. This tends to be difficult with win2k boxes. You may be better off with an appliance firewall or unix/linux system as your gateway. If you already have a good firewall then this is much less important.
There is considerable information on ICS on the internet. Also, like most microsoft programs it’s fairly simple to set up.

Is there a way to point Internet Explorer at a particular nic on a 2 nic system?
On the application layer IE doesn’t have that capabilities.
You can only set it on the network layer, by giving more weigh on the subnet 1 gateway on the routing table.
