The three sub-menus are described as follows:
•
Filter State of Interface – This is used to choose the default,
routing decisions for packets, not meeting the criteria for specific
filters.
•
Layer 2 Filter – This is a data-link layer (protocol independent)
filter. Foreknowledge of the specific protocol, used on the interface

•
IP Filter – This is an IP protocol specific filter, allowing you to,
among other things, prohibit specific packets from entering the LAN.
