All other parameters (Netmask, Gateway, DNS IP, WINS IP, State, & Domain Name) are identical to those in Dynamic IP Pool screen in the previous section.

DHCP Relay Agent

The DHCP Relay Agent feature allows the DI-206 to act as a go-between for a remote DHCP server assigning IP addresses to local clients. This can be useful if you wish to have all IP addresses in your company, including those in branch offices, assigned from a DHCP server centrally located at your headquarters, for example.

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-206 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-206 uses filters (configurable at two layers) to screen packet data, and apply a routing decision. There are two methods for configuring filters: 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.
