SecureNAT clients can be controlled only through the creation of
rules that limit traffic by IP address or subnet information.
NOTE
SecureNAT client support requires an ISA server to have more than one network interface
because the traffic must flow through the server from one network to the next.
This disallows a unihomed (single NIC) ISA server from handling SecureNAT or Firewall
clients. A unihomed server can handle Web Proxy clients only (for forward- or reverseproxy
support).
Defining the Web Proxy Client
A Web Proxy client is a client connection that comes from a CERN-compatible browser
client such as Internet Explorer or Firefox. Web Proxy clients interact directly with the
proxy server capabilities of ISA Server 2006, and relay their requests off the ISA server,
which operates as a content-caching solution to the clients. This enables commonly
downloaded content to be stored on the ISA Proxy server and served up to clients more
quickly. For more information on this concept, see Chapter 8, ???Deploying ISA Server 2006
as a Content Caching Server.???
