DHCP
Disable DHCP Server If another device on your network is the DHCP server for the VLAN, or if you will
configure the network settings of all of your computers manually, select the Disable
DHCP Server radio button to disable the DHCP server. By default, this radio button
is not selected, and the DHCP server is enabled.
Enable DHCP Server Select the Enable DHCP Server radio button to enable the UTM to function as a
Dynamic Host Configuration Protocol (DHCP) server, providing TCP/IP
configuration for all computers connected to the VLAN. Enter the following settings:
Domain Name This setting is optional. Enter the domain name of the UTM.
Starting IP
Address
Enter the starting IP address. This address specifies the first of
the contiguous addresses in the IP address pool. Any new
DHCP client joining the LAN is assigned an IP address
between this address and the ending IP address. The IP
address 192.168.1.2 is the default start address.
Ending IP Address Enter the ending IP address. This address specifies the last of
the contiguous addresses in the IP address pool. Any new
DHCP client joining the LAN is assigned an IP address
between the starting IP address and this IP address. The IP
address 192.168.1.100 is the default ending address.
Note: The starting and ending DHCP IP addresses should be
in the same network as the LAN TCP/IP address of the UTM
(that is, the IP address in the DMZ Port Setup section as
described earlier in this table).
Primary DNS
Server
This setting is optional. If an IP address is specified, the UTM
provides this address as the primary DNS server IP address. If
no address is specified, the UTM provides its own LAN IP
address as the primary DNS server IP address.
Secondary DNS
Server
This setting is optional. If an IP address is specified, the UTM
provides this address as the secondary DNS server IP
address.
WINS Server This setting is optional. Enter a WINS server IP address to
specify the Windows NetBIOS server, if one is present in your
network.
Lease Time Enter a lease time. This specifies the duration for which IP
addresses are leased to clients.
DHCP Relay To use the UTM as a DHCP relay agent for a DHCP server somewhere else in your
network, select the DHCP Relay radio button. Enter the following setting:
Relay Gateway The IP address of the DHCP server for which the UTM serves
as a relay.
