For a Microsoft Internet Security and Acceleration (ISA) Server 2000 version of this article, see 321516
This article describes how to connect a computer that is running either the Microsoft Windows Server 2003 Routing and Remote Access service or Internet Security and Acceleration (ISA) Server 2006 or ISA Server 2004 to a cable/DSL router and to access the Internet for browsing and e-mail for all clients on your local area network (LAN). If you use a DSL router, you do not have to use a Point to Point Protocol over Ethernet (PPPoE) driver on all Windows clients and on the Windows 2003-based server. In this environment, you have to make sure that you are using the correct routing configuration on both the DSL router and the server that is running either Routing and Remote Access or ISA Server. The DSL router has to know about all networks that are behind the Windows 2003-based server to be able to return all answers to the client's LAN.
The following configuration is an example of a network and an IP configuration:
Internet |--| IP-address_from_ISP - DSL_Router - 192.168.1.1 |--| 192.168.1.2 - Windows_Server_2003 - 192.168.168.249 |--| Hub_or_switch |--| Clients
This configuration uses the following settings:
If you experience connectivity issues on clients, check the routing table on the DSL router. You can access most devices by using an HTTP Web page (such as http://192.168.0.1). If the route is not present, add a static route to the client's network. To do so, use the following settings:
ISA Server has a built-in routing functionality. For more information about this functionality, see the Microsoft ISA Server Help.
