LAN Configuration 4-9
v1.0, September 2009
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 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 (the IP address in LAN TCP/IP section above).
Primary DNS
Server
This 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 uses the VLAN
IP address as the primary DNS server IP address.
Secondary DNS
Server
This is optional. If an IP address is specified, the UTM
provides this address as the secondary DNS server IP
address.
WINS Server This 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 Select the DHCP Relay radio button to use the UTM as a DHCP relay agent for
a DHCP server somewhere else on your network. Enter the following setting:
Relay Gateway The IP address of the DHCP server for which the UTM
serves as a relay.
