MCSE ISA Server 2000- P15: These books include a large amount and different kinds of information. The many different elements are designed to help you identify information by its purpose and importance to the exam and also to provide you with varied ways to learn the material. | Chapter 13 PLANNING AND DEPLOYING CLIENTS 393 Do you want to improve efficiency of the ISA Server computer for caching Web proxy clients will directly use the Web proxy service. SecureNAT clients and Firewall clients use the firewall service and their HTTP requests are forwarded to the Web proxy service. Do you have client operating systems and types other than Windows Other clients such as Macintosh Unix and Linux can utilize SecureNAT and Web proxy client types. Would you like to cache FTP requests Use Web proxy clients. FTP requests made through the Web proxy application can be cached. Evaluating Network Infrastructure Changes Installing ISA Server s to provide Internet access control and or Web caching capability can result in numerous network infrastructure changes. The cost and complexity of deploying and maintaining these changes is dependent on the type of clients to be used as well as the nature of your infrastructure. SecureNAT client s potential entails few infrastructure changes. This does not mean the cost will be low rather that the modifications are simple. If SecureNAT clients need to be pointed directly to the internal interface of the ISA Server that information can be provided in DHCP or manual configured for those clients with static IP addresses. If multiple SecureNAT clients must be directly visited then you must budget your time and cost accordingly. In a larger environment however SecureNAT clients may already be pointed to network routers for internal routing. These routers must be configured to route Internet requests to the ISA Server. Your time and cost is dependent on the number of routers that must be configured and the complexity of this configuration change. If Web proxy or Firewall clients need to be configured for automatic discovery then you may need to configure DHCP and or DNS servers to provide information on where to locate the ISA Server. The protocol used in the Win Proxy Automatic Discover WPAD protocol. 394 Part IV .
