SUMMARY
Windows 2000 and Windows Server 2003 have the ability to define Internet protocol (IP) packet filters for protocol numbers. IP packet filters are commonly used to restrict traffic in and out of each interface.



MORE INFORMATION
Protocol numbers are used to configure firewalls, routers, and proxy servers. In Internet Protocol version 4 (IPv4, Request for Comments [RFC] 791I), the protocol number can be found in the Protocol field of an IP header.

The following section contains a list of currently assigned IP protocol numbers. For more information about this topic (including references), please visit the following Internet Assigned Numbers Authority (IANA) Web site:

Assigned Internet Protocol Numbers
NOTE: The protocols numbers are shown in decimal notation.
