FPCTunnelPortRange Object

The FPCTunnelPortRange object provides access to the tunnel port range.

A tunnel port allows ISA to work as a data pump for communication to particular ports on an external server. Because this effectively bypasses ISA protocol rules, the external port ranges for which this is possible are set by default to 443–443; that is, the single port 443 (SSL), and to 563–563, the single port 563 (NNTP). You can use the FPCTunnelPortRange object to change the port range in which a tunnel port can be created.

The following VBScript is an example of how to add ports to the tunnel port range.

set isa=CreateObject("FPC.Root")
set tprange=isa.Arrays.GetContainingArray.ArrayPolicy.WebProxy.TunnelPortRanges
set tmp=tprange.AddRange("SSL 3520", 3520, 3520)
set tmp=tprange.AddRange("SSL 3529", 3529, 3529)
tprange.Save
