Properties

AppId	Gets the app ID representing the app that caused this packet to flow. This is present only on the first packet of a flow. The presence of this property indicates it is the first packet.
Buffer	Gets the memory buffer object, designed to contain packets of date to be sent or received as part of a IVpnPacketBufferList.
Status	Gets the status of VpnPacketBuffer. The status property may be used to report errors when manipulating the IVpnPacketBufferList.
TransportAffinity	Gets or sets a number specifying which transport object to use as specified in the VpnChannel:Start* methods. This allows the selection between the main and the optional transports.
TransportContext	Gets or sets a transport context object, for example the name of a host or server.
