SetAdaptersStartupMode
BOOL
SetAdaptersStartupMode ( DWORD
dwAdaptersStartupMode );
Return Value:
TRUE if call was
successful, FALSE otherwise
Parameters:
dwAdaptersStartupMode
- must be a combination of the XXX_LISTEN or
XXX_TUNNEL flags:
- MSTCP_FLAG_SENT_TUNNEL - queue all
packets sent from MSTCP to network interface. Original packet
dropped.
- MSTCP_FLAG_RECV_TUNNEL - queue all
packets indicated by network interface to MSTCP. Original packet
dropped.
- MSTCP_FLAG_SENT_LISTEN - queue all
packets sent from MSTCP to network interface. Original packet goes
ahead.
- MSTCP_FLAG_RECV_LISTEN - queue all
packets indicated by network interface to MSTCP. Original packet
goes ahead.
Version 2.3 of
WinpkFilter has added three new flags:
- MSTCP_FLAG_FILTER_DIRECT - In
promiscuous mode TCP/IP stack receives all packets in the Ethernet
segment and replies with various ICMP packets, to prevent this set
this flag. All packets with destination MAC different from
FF-FF-FF-FF-FF-FF and network interface current MAC will never
reach MSTCP.
By default loopback
packets are passed to original MSTCP handlers without processing,
to change this behavior use the flags below:
- MSTCP_FLAG_LOOPBACK_FILTER - Pass
loopback packet for processing by helper driver routines
(redirected to user-mode if requested).
- MSTCP_FLAG_LOOPBACK_BLOCK -
Silently drop loopback packets, this flag is recommended for usage
in combination with promiscuous mode to avoid multiply processing
of one packet.
Remarks:
This routine sets the
default mode to be applied on the each adapter when it appears in
the system.. It can be useful when you need to prevent
network interface to start operating before your application has
started. Important note, this API call requires a system reboot to
take effect.
