Configure the Authentication Provider

After the Routing and Remote Access and Demand-Dial Interface wizards complete, Windows authentication and Windows accounting are selected by default. You can change these defaults from Windows authentication and Windows accounting to RADIUS authentication and RADIUS accounting, or you can choose separate providers for authentication and accounting. For a deployment that supports only a site-to-site connection, use Windows authentication and Windows accounting. However, you can change these defaults if the same answering router will support both the site-to-site connection and remote access users, and you want to use RADIUS as either the authentication provider or the accounting provider.

Use the following procedures to accomplish these tasks:

• Configure the authentication provider on the answering router.
  
• Configure the accounting provider on the answering router.
  

To configure the authentication provider on the answering router

1. Configure either Windows authentication or RADIUS authentication.
   
   For information about how to configure Windows or RADIUS authentication, see Use Windows Authentication or "Use RADIUS authentication" in Help and Support Center for Windows Server 2003.
   
2. If you select RADIUS authentication, add the answering router as a RADIUS client on the IAS server.
   
   For information about how to add the answering router as a RADIUS client, see "Configure RADIUS Clients" in Help and Support Center for Windows Server 2003.
   

To configure the accounting provider on the answering router

1. Select either Windows accounting or RADIUS accounting.
   
   For information about how to select the accounting method you want to use, see Use Windows Accounting or "Use RADIUS accounting" in Help and Support Center for Windows Server 2003.
   
2. If you select RADIUS accounting, add the answering router as a RADIUS client on the IAS server.
   
   For information about how to add the answering router as a RADIUS client, see "Configure RADIUS Clients" in Help and Support Center for Windows Server 2003.
