FPCIpOptions Object

The FPCIpOptions object enables configuration of the IP options checking mechanism for Forefront TMG. Forefront TMG checks for IP options, which are included in the header of an IP packet. Using this object you can configure whether the mechanism checks for all or some IP options, and whether a packet with those options will be denied.

Forefront TMG has four modes of operation when inspecting the packets for IP options, which are specified by values defined in the FpcIpOptionsAction enumerated type:

fpcAllowPacketsIpOptions

A packet is allowed to pass no matter what IP options it may have.

fpcDenyPacketsIpOptions

A packet is dropped if it has any IP option.

fpcAllowPacketsSelectedIpOptions

Selected IP options are allowed, and a packet is denied if it has an IP option other than those on the list of selected IP options.

fpcDenyPacketsSelectedIpOptions

Selected IP options are not allowed, and a packet is dropped if it has any option that is in the list of selected IP options.

This object can be accessed through the IPOptions property of an FPCAttackDetection object.

Methods Inherited from FPCPersist

Name Description
CancelWaitForChanges Cancels the registration established by the WaitForChanges method (for use in C and C++ programming only).
CanImport Returns a Boolean value that indicates whether the object's properties can be imported from the specified XML document.
Export Writes the stored values of all of the object's properties to the specified XML document.
ExportToFile Writes the stored values of all of the object's properties to the specified XML file.

Import Copies the values of all of the object's properties from the specified XML document to persistent storage.
ImportFromFile Copies the values of all of the object's properties from the specified XML file to persistent storage.
LoadDocProperties Provides the XML document's properties so that you can know what information can be imported from the document.
Refresh Reads the values of all of the object's properties from persistent storage, overwriting any changes that have not been saved.
Save Writes the current values of all of the object's properties to persistent storage.
WaitForChanges Registers to wait for an event indicating that the contents of the object have changed (for use in C and C++ programming only).
