INTRODUCTION
Microsoft Internet Security and Acceleration (ISA) Server 2004 is designed so that communication between different networks should traverse ISA Server. It is not intended that clients on a specific network should use ISA Server to access resources on the same network. This configuration is known as looping back through the ISA Server computer. You can provide access between internal clients on a specific network to resources on a different network in several ways.

Generally, you use access rules determine how clients on a source network access resources on a destination network. However, in some circumstances, it may be appropriate to configure internal client access by using a server publishing rule instead of using an access rule that permits access by using a specific protocol.
