Setting Up the ISA Server as an IAS Client
IAS needs to be configured to allow the authentication request from the ISA VPN server.
The following procedure can be used to set up IAS on both a Windows 2000 server and a
Windows 2003 server. The IAS client in this case refers to the ISA VPN server, as it acts as a
client for the IAS service.
1. Open the Internet Authentication Service console.
2. Right-click RADIUS Clients and select New RADIUS Client from the context menu.
3. On the Name and Address properties window, enter the friendly name and client
address in the fields provided. The friendly name can be any name used to identify
the ISA server. The client address can be either the host name or IP address of the
internal interface on the ISA server, as shown in Figure 9.11. Click Next to continue.
4. On the Additional Information properties window, select Microsoft from the Client-
Vendor drop-down list.
