I have a new SBS 2008 server that can get on the Internet, but client members cannot. I've run the Getting Started Tasks successfully.

The server has 2 NICs. The LAN side connection details are:

IP 192.168.0.25, NM 255.255.255.0, DNS 192.168.0.25. The LAN connects to the switch all clients connect to.

The Internet side connection details are:
IP is 192.168.1.25, NM 255.255.255.0, GT 192.168.1.251, DNS 192.168.0.25, 192.168.1.251. The WAN connects to our router at 192.168.1.251

DNS forwarding points to the DNS servers for our broadband providers.

Does anyone have an idea why the client computers cannot connect to the Internet. They can connect to server shared resources.

You have SBS misconfigured.  SBS 2008 (UNLIKE 2003) does NOT support dual NICs.  You should be disable the internet connected NIC and use the router for all devices - server and workstations.

Right now the server is the link between the switch all clients connect to and the router. If I understand correctly, I need to connect router -> switch and server -> switch (NIC 1) and disable NIC 2, instead of router -> server (NIC 1), server -> switch (NIC 2). Is that what you mean?
