Routing Problem with W2K Server

I have recently set up a Windows 2000 Server with two network interface cards. My intent is to use the first card to connect to my LAN and the second to connect to my WAN (DSL).

The cards themseves appear to be configured properly as I can browse the Internet from the W2K Server's browser and also access my other computers on the internet from the same machine but I must be missing a step somewhere as none of the computers on the LAN can get to the Internet.

The WAN card is configured asfollows:

IP Address: 165.184.231.73
Subnet Mask: 255.255.255.252
Default Gateway: 165.184.231.74 (I assume this is the IP that the DSL 'modem' is assigned)
Preferred DNS: 64.34.8.36
Alternate DNS: 216.227.0.68

The LAN card is configured as follows:

IP Address: 192.168.10.201
Subnet Mask: 255.255.255.0
Default Gateway: 165.184.231.73
Preferred DNS: 64.34.8.36
Alternate DNS: 216.227.0.68

I followed the Setup Wizard for RRAS to configure the computer as a Router and acceptedall the defaults but there does not seem to be any IP routing passing from the LAN side to the WAN side - I figure that I am missing a step or two to accomplish this.

Can someone please help me with whatever I am missing here?

Any help will begreatly appreciated, thank you in advance.

For everyone else to be able to use the internet through your connection, you have to either create your server as a router or share the internet connection that you use to get to the internet. Another way to give them internet access is to configure their network card's gateway as the ip of the router for the DSL or your server, if you set it up as a router. Hope this helps, Jeremy

In order for this to work, you have to enable IP forwarding on both your NICs on the server (not recommended because of security issues) or configure NAT routing on your server. Here's a TechNet article that describes how to configure a Win2K server as a NAT router: Q299801 (if you don't have TechNet CDs, go to www.microsoft.com/technet and search for the article #). Hope this helps!

Both previous answers will work, but I have found that a product from Linksys which is a cable/dsl router/switch (BEFSR41) does a great job of handling all needs for sharing a internet connection, all for $75.00. It will provide DHCP/Firewall/Packet filtering.
