Configure Dynamic Host Configuration Protocol

The router uses Dynamic Host Configuration Protocol (DHCP) to allow users in a small office environment to be added and removed from a network with all of the network information (i.e. IP address, DNS, subnet mask, etc.) being configured automatically. DHCP configures devices (DHCP clients) from a central DHCP server. It is designed to allocate network addresses to a number of hosts on the router’s LAN and supply the minimal configuration needed to allow hosts to operate in an IP network.

The following steps must be performed on the router to configure it as a DHCP server.

7	DHCP Services

	DHCP Services options which are available are none, relay and server.
7	Set to server to enable this device as a DHCP Server.
	IP Address Pool

	Ä Server IP address pool
	Ä IP address pool
	Ä IP Address / number of addresses
	The IP address pool option requires setting the first IP address in the
	range that is to be used for the devices attached to the DHCP Server.
	The number of addresses to be assigned must also be specified, to a
	maximum of 253.
	When setting up a router as a DHCP server, you may not assign an address
	pool that includes broadcast addresses (all ones in the host portion of the IP
	address) for known networks. Known networks include any local networks
	plus standard A, B and C class addresses.
	With the DHCP Services and IP Address Pool defined, devices may be attached to the
	network (up to the maximum specified) and they will be automatically configured.
	When setting up a router as a DHCP server that will have both a DNS server
	on the internal network and a remote connection to another DNS server (for
	example, through an ISP), then the local DNS server should be set as the
	primary DNS and the external DNS server as the secondary DNS.
