Hi, WinPcap protocol driver works in parallel with MSTCP protocol. It allows you to see all packets, analyze them and even generate new ones, but does not allow preventing MSTCP stack from sending/receiving any packet to/from the network. In order to able to block packets destined to/from MSTCP you should place your driver between MSTCP and network interfaces. For these purposes you can use NDIS IM (NDIS intermediate driver), Filter-hook driver or NDIS hooking one (an example something like WinpkFilter http://www.ntkernel.com/products/winpkfilter.shtml).
Hope it helps, Vadim -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Monday, February 07, 2005 1:52 PM To: winpcap-users@winpcap.polito.it Subject: [WinPcap-users] How to Block packet Hi, can someone help me? I have a question about packets that come through WinPcap driver, can I stop packets, analyze it and, only if these packets not match a filter, delete them?
