The FPCIpPacketFilters collection provides access to a group of IP packet filter objects in an ISA array. An IP packet filter monitors all network traffic to determine whether the packets can be communicated. If the packet passes through the filter, the data is then passed up to the application layer. An individual IP packet filter is either an allowing or blocking filter. Allowing filters permit communication between specified IP addresses by using the specified protocols and ports. Blocking filters block communication between specified IP addresses by using the specified protocols and ports.
This collection is a property of an FPCArrayPolicy object.

This collection implements the IFPCIpPacketFilters interface.
The following table lists the methods of the FPCIpPacketFilters collection.
| Method | Description |
|---|---|
| Add | Creates a new FPCIpPacketFilter object in the collection and returns a reference to it. |
| Item | Retrieves the given FPCIpPacketFilter object from the collection. |
| Refresh | Reads the collection's configuration information from persistent storage, discarding any changes to the configuration that were not saved. |
| Remove | Removes an IP packet filter object from the collection. |
| Save | Saves the object's configuration to persistent storage. |
