Section 4: Advanced Configuration 18
DHCP Server Tab
The DHCP Server tab enables Dynamic Host Configuration Protocol (DHCP) server functionality on the LAN,
allowing the router to dynamically assign lease IP addresses to clients that connect to it from the local
network.
Be sure to click Apply once you have made changes.
DHCP Server Tab Fields
Field or Button Description
Enable DHCP Server
If selected, the DHCP server on the gateway
assigns IP addresses to the computers and
other hosts on your network if they have
DHCP enabled. By default, the gateway
server is enabled. If there is another DHCP
server running on your network (on another
router), you must disable one of the DHCP
servers.
If not selected, you must carefully configure
the IP address, Subnet Mask, and DNS
settings of every host on your network. Do
not assign the same IP address to more
than one host. Your gateway must be on the
same subnet as the other hosts.
DHCP Server IP Address
Enter the default port forwarding LAN Client
IP Address.
DHCP Starting IP Address
Sets the first IP address assigned by the
DHCP server, in dotted-decimal format. It
must be greater than the IP address value of
the gateway. For example, if the IP address
of the gateway is 192.168.15.1 (default), the
starting IP address must be 192.168.15.2 (or
higher).
DHCP Ending IP Address
Sets the final IP address assigned by the
DHCP server. If the DHCP server runs out of
DHCP addresses, users cannot access
network resources. If this happens, increase
the Ending IP (to the limit of 254) or reduce
the Lease Time.
DHCP Lease Time
Sets the time, in seconds, that a network
computer remains connected to the
gateway using its current assigned IP
address. At the end of this time, the DHCP
server renews the lease or assigns the
computer a new IP address. The default is 1
hour. The maximum is about 278 hours.
