The new TechNet Cable Guy article for June 2005, titled "TCP/IP Packet
Processing Paths", is a discussion of the basic architecture of the TCP/IP
protocol for IP version 4 and the additional components that process
packets, and the packet processing paths for unicast traffic sent, received,
and forwarded by Windows-based computers. Detailed knowledge of the IP
packet processing path can make it easier for you to understand how to
configure and troubleshoot packet processing and filtering components such
as Internet Protocol security (IPsec) and Windows Firewall.
