D-Link DI-1162 manual Filter Configuration, Configuring a Filter Set

DI-1162 Remote Access Router

•Time Threshold – this specifies the maximum amount of time (in seconds) since the host began requesting an IP address. If the value define here is exceeded, the relay agent will not pass along the request from the host.

•State – enables/disables the DHCP Relay Agent function.

Filter Configuration

Your DI-1162 uses filters (configurable at two layers) to screen packet data, and apply a routing decision. There are two methods of configuring a filter: you can configure a filter at the network layer (IP filter) to restrict access between networks and reduce unnecessary internetwork traffic; and you can configure a filter at the data-link layer (a general filter) to provide a protocol independent filter.

Good knowledge of network protocols is required to configure a specific filter appropriately. It is important for the router to operate correctly, therefore, necessary packets must be allowed to pass through the filters. In other words, do not attempt to configure filters on a utilized router unless you understand what you are doing.

The following section describes how to configure the router filter parameters.
