Items are described as follows:
♦
DHCP Server IP Address – This is the IP address of the remote DHCP server. When a local computer
powers up and sends a DHCP request for an IP address, the DI-1162/DI-1162M will forward the request to the
address specified here.
♦
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 or disables the DHCP Relay Agent function.
Filter Configuration
Your DI-1162/DI-1162M 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.
