Constructing the Local Address Table

The Local Address Table (LAT) consists of a series of IP address ranges that define your internal network address space. Typically, the LAT contains all IP addresses associated with the internal network cards on the ISA Server computer, in addition to the private IP address ranges defined by the Internet Assigned Numbers Authority (IANA). For more information see the ISA product documentation.

You can use the ISA administration COM objects to build the LAT. The folder SDK\samples\admin\scripts includes the ConstructLAT script that constructs a LAT. It is provided in both VBScript and JScript.

Adding a LAT Entry

The following VBScript code demonstrates how to add an entry to the LAT:

Set objFPC  = CreateObject ("FPC.Root")
Set objNetConfig = objFPC.Arrays(1).NetworkConfiguration
Set objLAT = objNetConfig.LAT
ObjLAT.Add "2.2.2.2","3.3.3.3"
ObjLAT.Save
