SUMMARY
This article describes how to enable dial-out access on the following Microsoft Internet Security and Acceleration Server 2000 (ISA) clients:
 * Winsock Proxy
 * Firewall
 * SecureNAT



MORE INFORMATION
For ISA to use a modem, or virtual-private-network (VPN) connection to make connections to an upstream network, you need to enable this in the Network Configuration section of the ISA Management Console. This requires a different configuration in addition to what is necessary to satisfy Web Proxy requests.

To use a modem, or VPN connection as a primary connection for Firewall, Winsock Proxy, or SecureNAT clients by using the ISA Management Console, follow these steps:
 * 1) Create a Dial-up connection on the server under Windows 2000 Network and Dial-up connections. If the server is in an array, create Dial-up Networking (DUN) entries with identical names on all servers in the array.
 * 2) In the ISA Management Console, create a Dial-up Entry under  , and then Policies Elements - Dial-up Entries.
 * 3) Right-click Network Configuration in the ISA Management Console, and then click Properties.
 * 4) Click Use primary connection, and then click Use dial-up Entry.

Note: If you do not click to select the Use dial-up entry check box in the ISA Management Console, even if you manually establish a DUN connection to a network provider, ISA SecureNAT, or Winsock Proxy will not correctly forward packets, even if HTTP, and SHTTP are proxied correctly.
