DHCP Server Settings

The DFL-200 contains a DHCP server. DHCP (Dynamic Host Configuration Protocol) is a
protocol that allows network administrators to automatically assign IP numbers to DHCP
enabled computers on a
network. The DFL-200
DHCP Server helps to
minimize the
necessary to administer
a network, as there is no
need for another DHCP
server.
The DFL-200 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

The DFL-200 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-200 also includes a DHCP Relay function. A DHCP Relay allows the DFL-200 to
receive DHCP requests and forward those requests to a specified DHCP server. The relay
function allows the use of existing DHCP servers in conjunction with the DFL-200 to ensure all
users on all interfaces receive IP addresses when requested.
configure dynamic routes based on those DHCP 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.
