Server 2003 Domain No Internet to network

[jhonea]

I am running a Server 2003 domain, and trying to get the computers on the network to connect to the internet. Here is what I have so far:

-The server CAN connect to the internet.

-The computers on the network can connect to the server and access the shared files, however they cannot access the internet.

The network TCP/IP settins are as follows:

Network Card 1. (hooked to network switch)
IP: 192.168.200.1
Subnet Mask: 255.0.0.0
Gateway: 75.51.62.153
DNS: 192.168.200.1

Network Card 2. (hooked to DSL router)
IP: 75.51.62.154
Subnet Mask: 255.255.255.252
Gateway: 75.51.62.153
DNS: 67.134.189.215

I'm pretty sure the settings for Network Card 1 are probably wrong. Any suggestions?
