在普通的windows 2000下实现实现包过滤的方法主要是书写ndis过滤驱动程序，需要的技巧比较高，而且烦琐，需要考虑很多细节。但是对于很多应用而言，只需要能更方便的对ip包进行过滤处理，其实ndis对于ip包的过滤提供一种书写过滤钩子驱动的方式，主要方法是：
驱动中建立一个普通的设备，然后通过ioctl_pf_set_extension_pointer操作将你的内核模式的过滤钩子挂接到系统默认的ip过滤驱动上，这样你就可......

where and how to get new rfcs
=============================
rfcs may be obtained via email or ftp from many rfc repositories. the
primary repositories will have the rfc available when it is first
announced, as will many secondary repositories. some secondary
repositories may take a few days to make available the most recent
rfcs.
many of these repositories also now have world wide web servers. try
the following url as a starting point:
http://www.rfc-editor.org/
primary repositories:
rfcs can be obtained via ftp from nis.nsf.net, ftp.rfc-editor.org,
wuarchive.wustl.edu, src.doc.ic.ac.uk, ftp.ncren.net, ftp.nic.it,
ftp.imag.fr, ftp.ietf.rnp.br www.normos.org, ftp.gigabell.net,
or oasisstudios.com.
1. nis.nsf.net
to obtain rfcs from nis.nsf.net via ftp, login with username
"anonymous" and password "name@host.domain"; then connect to the
directory of rfcs with cd /internet/documents. the file name is
of the form rfcnnnn.txt (where "nnnn" refers to the rfc number).
for sites without ftp capability, electronic mail query is available
from nis.nsf.net. address the request to nis-info@nis.nsf.net and
leave the subject field of the message blank. the first text line of
the message must be "send rfcnnnn.txt" with nnnn the rfc number.
contact: rfc-mgr@merit.edu
2. ftp.rfc-editor.org
rfcs can be obtained via ftp from ftp.rfc-editor.org, with the
pathname in-notes/rfcnnnn.txt (where "nnnn" refers to the number of
the rfc). login with ftp username "anonymous" and password
"name@host.domain&q...
