Information about the version of Firewall Client for ISA Server that was released in September 2006

Firewall Client for ISA Server can be installed on client computers that access Microsoft Internet Security and Acceleration (ISA) Server. Firewall Client for ISA Server provides enhanced security features, application support, and access control for client computers. This program also provides the following functionality:

• Authentication for Winsock programs that use TCP and UDP
• Support for complex secondary protocols
• User and application information for the ISA Server logs

When a client computer that is running Firewall Client for ISA Server makes a request, the destination is evaluated by the firewall client program. Then, external requests are directed to the ISA Server computer for handling. No specific routing infrastructure is required. The firewall client sends user information transparently with each request. This arrangement lets you create ISA Server firewall policy rules that use the authentication credentials that are presented by the client.

Note ISA Server lets you configure automatic discovery for firewall client computers by using a Web Proxy Automatic Discovery (WPAD) entry in DNS or in DHCP. By this method, ISA Server obtains Web proxy settings that correspond to the clients' respective locations.
