Configuring DHCP: DHCP Server Overview

DHCP Server Overview
The DHCP server lets hosts connected to Remote RMX-3200's Ethernet interfaces or
bridge WAN interfaces request and obtain IP addresses from Remote RMX-3200. It
also lets hosts discover information about the network to which they are attached.
Available IP addresses are allocated by a network administrator who enters them into
a DHCP configuration file. The
DHCP protocol then automatically assigns new IP
addresses to hosts from the pool of IP addresses.
At startup, the DHCP server reads the DHCP configuration file and stores a list of
available addresses on each subnet in memory. When a client requests an address,
the DHCP server allocates an address for it. Each client is assigned a lease that
expires after an amount of time chosen by the administrator. Clients to which leases
are assigned are expected to renew them in order to continue to use the addresses.
Once a lease has expired, the client to which that lease was assigned is no longer
permitted to use the leased IP address.
Configuring DHCP Client Support
Providing DHCP client support on Remote RMX-3200 will allow the Remote RMX-
3200 device to dynamically configure its network information from a DHCP server.
This reduces the amount of configuration required from the user to gain network
access to a Remote RMX-3200 and centralizes the control of IP address to a single
DHCP server. With the DHCP client enabled on an interface, Remote RMX-3200 has
the ability to dynamically configure an interface's IP address, DNS server information,
domain name information and NTP server information.
Note: For more information on DHCP, refer to the dhcpd linux man page.
