This article describes how to configure Microsoft Internet Security and Acceleration (ISA) Server 2004 to use a dial-up connection for Internet access. This configuration enables dial-out Internet access for Winsock Proxy clients, Microsoft Firewall clients, and SecureNAT clients.

To configure ISA Server 2004 to use a modem or a virtual private network (VPN) connection to connect to an upstream network, follow these steps:
| 1. | Create a dial-up connection or a VPN connection on the computer where ISA Server is installed. This computer can be running Microsoft Windows 2000 Server or Microsoft Windows Server 2003. |
| 2. | Start the ISA Server Management tool. |
| 3. | Expand ServerName where ServerName is the name of your ISA Server computer.
|
| 4. | Expand Configuration, and then click Networks.
|
| 5. | In the right pane, click the Tasks tab, and then click Specify Dial-up Preferences.
|
| 6. | Click Allow automatic dialing to this network, click External in the list of networks, and then click to select the Configure this dial-up connection as the default gateway check box if you want to use this connection as your default route to the Internet. |
| 7. | Click Select, click the dial-up connection that you want ISA Server to use in the Network Dial-up Connection list, and then click OK.
|
| 8. | Click Set Account, type the account credentials for the dial-up connection, and then click OK.
|
| 9. | Click OK, click Apply to save your changes and to update the firewall policy, and then click OK.
|
| 10. | Verify that a default gateway is not configured on any one of the internal network adapters on the ISA Server computer.
