DHCP Server Settings

The DFL-700 contains a DHCP server. DHCP (Dynamic Host Configuration Protocol) is a
protocol that allows 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.
Note: There can only be one DHCP Server or DHCP Relay configured per interface.
