The IPX_TRAFFIC_FILTER_INFO structure MAY<89> be used to specify the filter data for an IPX interface. When this structure is encapsulated in RTR_TOC_ENTRY (section 2.2.1.2.4), the InfoType value MUST be 0x00000006 or 0x0000000C. If the value of InfoType is 0x00000006, the filter is applied to incoming traffic, if the value of InfoType is 0x0000000C, the filter is applied to outgoing traffic.

FilterDefinition: Flags that specify relevant IPX address fields to filter on. The values MUST be one of the following values.

Value	Meaning
IPX_TRAFFIC_FILTER_ON_SRCNET 0x00000001	Apply filter on source network.
IPX_TRAFFIC_FILTER_ON_SRCNODE 0x00000002	Apply filter on source node.
IPX_TRAFFIC_FILTER_ON_SRCSOCKET 0x00000004	Apply filter on source socket.
IPX_TRAFFIC_FILTER_ON_DSTNET 0x00000010	Apply filter on destination network.
IPX_TRAFFIC_FILTER_ON_DSTNODE 0x00000020	Apply filter on destination node.
IPX_TRAFFIC_FILTER_ON_DSTSOCKET 0x00000040	Apply filter on destination socket.
IPX_TRAFFIC_FILTER_ON_PKTTYPE 0x00000100	Apply filter based on packet type.
IPX_TRAFFIC_FILTER_LOG_MATCHES 0x80000000	Apply filters based on log matches.

DestinationNetwork: The DestinationNetwork field identifies the network (a segment of the IPX internetwork bounded by the IPX routers) to which an IPX node is connected.

DestinationNetworkMask: The mask that MUST be logically ANDed with DestinationNetwork.

DestinationNode: Identifies a node on an IPX network. The 6-byte fields can be used to store physical addresses, also known as MAC addresses.

DestinationSocket: Identifies the software process addresses of the destination and source applications respectively. With multiple processes communicating between the same two computers, the IPX network and node numbers are the same. The IPX socket number is a software process identifier that is used to forward the IPX payload to the proper process.

SourceNetwork: Identifies the network (a segment of the IPX internetwork bounded by the IPX routers) to which an IPX node is connected.

SourceNetworkMask: The mask that MUST be logically ANDed with SourceNetwork.

SourceNode: Identifies a node on an IPX network. The 6-byte fields can be used to store physical addresses, also known as MAC addresses.

SourceSocket: Identifies the software process addresses of the destination and source applications respectively. With multiple processes communicating between the same two computers, the IPX network and node numbers are the same. The IPX socket number is a software process identifier that is used to forward the IPX payload to the proper process.

PacketType: The PacketType field indicates the contents of the payload portion of the IPX packet. It allows several client protocols to use the IPX and be identified by the IPX router. The following table lists some common defined values of the IPX packet type.

Value	Meaning
0x0000	Unspecified
0x0001	RIP
0x0004	SAP/Normal IPX
0x0005	SPX
0x0014	IPX WAN broadcast (used for NetBIOS over IPX broadcasts)
