|Microsoft Internet Security and Acceleration Server 2000|
The Internet Security and Acceleration (ISA) Server 2000 consists of the Firewall service, application filters, the Web proxy service, and Web (ISAPI) filters. An HTTP redirector filter diverts all HTTP requests to the Web proxy service.
The ISA firewall also provides dynamic Internet Protocol (IP) packet filters to evaluate packets, and Secure Network Address Translation (SecureNAT) to enable NAT clients to connect through ISA. Also, ISA Server uses the bandwidth control of Windows® 2000 Quality of Service (QOS) to allow you to manage bandwidth use.
