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.

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.
