On more complex or routed networks the SecureNAT client has a default gateway set to a router interface that can route Internet-bound requests to the internal interface of the ISA server. The primary disadvantage of using the SecureNAT client is that it cannot pass authentication information to the ISA server and therefore you cannot configure access controls based on user or group information. Solutions Fast Track Understanding ISA Server Architecture n Proxy Server was built on three basic services the Web Proxy Service the Winsock Proxy Service and the SOCKS Proxy Service. n The four components that form the foundation of the ISA Server are the Web Proxy Service the Firewall Service the Network Address Translation Protocol driver and the Scheduled Content Download Service n The Web Proxy Service provides and controls access to the Web protocols which are Application layer protocols. n The Web Proxy Service is implemented as the file. You can start and stop the service via the net start and the net stop commands. n The Web Proxy Service is also responsible for the Web cache which provides a mechanism that allows content retrieved from the Internet to be stored on the ISA server. n The Firewall Service provides the same functionality to network clients as the Winsock Proxy Service did in Proxy Server . n The firewall client installs a special version of the Windows Sockets Winsock interface. The Winsock interface is a Session layer interface and is implemented as an API. n The firewall client software captures Winsock API calls and forwards them to the Firewall Service via the Firewall Service s control channel. n The Network Address Translation NAT Protocol driver allows network clients on a network that uses a private IP addressing scheme to access the Internet. n To solve the .
