Configuring a Filter Set

Under the Advanced Functions menu, select Filter Configuration. You will see the following screen:

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 (LAN or WANs), is needed to make effective use of this filter.

•IP Filter – This is an IP protocol specific filter, allowing you to, among other things, prohibit specific packets from entering the LAN. Alternatively, you can set up filters that allow certain types of IP packets to enter the LAN.

Filter State of Interface

The Filter State of Interface sub-menu lets you disable a filter, or, for packets that have not met the corresponding criteria, to forward or drop packets.
