FPCIpOptions

Internet Security and Acceleration Server 2004/2006 SDK

The FPCIpOptions object enables configuration of the IP options checking mechanism for ISA Server. ISA Server 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.

ISA Server 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

The FPCIpOptions object defines the following methods.

Method Description
Clear Clears the specified IP option.
ClearAll Clears all of the IP options.
IsSelected Queries whether the specified IP option is selected.
Select Selects the specified IP option.
SelectAll Selects all of the IP options.

Properties

The FPCIpOptions object has the following property.

Property Description
IpOptionsAction Gets or sets a value from the FpcIpOptionsAction enumerated type that specifies whether packets will be allowed or denied with consideration of the IP options included in them.

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.
GetServiceRestartMask Retrieves a 32-bit bitmask of the FpcServices enumerated type that specifies which services need to be restarted for currently unsaved changes to take effect.
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).

Properties Inherited from FPCPersist

Name Description
PersistentName Gets the persistent name of the object. The persistent name of an object is a name that is unique for the object at the respective level of the COM object hierarchy.
VendorParametersSets Gets an FPCVendorParametersSets object that can hold sets of custom data for extending the object.
