Servers

DHCP Server Settings

The DFL-700 contains a DHCP server; DHCP (Dynamic Host Configuration Protocol) is a

protocol that lets network administrators to automatically assign IP numbers to computers on

a network. The DFL-700

DHCP Server helps to

minimize the work

necessary to administer

a network, as there is

no need for another

server running DHCP

Server software.

The DFL-700 DHCP

Server only implements

a subset of the DHCP

protocol necessary to

serve a small network,

these are:

•

IP address

•

Netmask

•

Subnet

•

Gateway

address

•

DNS

Servers

•

WINS

Servers

•

Domain

name

The DFL-700 DHCP

Server assigns and manages IP addresses from specified address pools within the firewall to

the DHCP clients.

Note:

Leases are remembered over a re-configure or reboot of the firewall.

The DFL-700 also includes a DHCP Relayer. A DHCP relayer is a form of gateway

between a DHCP Server and its users. The relayer intercepts DHCP queries from the users

and forwards them to a DHCP server while setting up dynamic routes based on leases. This

enables the firewall to keep an accurate routing table based on active users and protects the

DHCP server to some degree among other things.

Note:

There can only be one DHCP Server or DHCP Relay configured per interface.
