Enable DHCP Server
To use the Router as your network’s
DHCP server, select
Enable DHCP Server
. If you already
have a DHCP server on your network, remove the check
mark. Then configure the Dynamic IP settings.
Dynamic IP
Client Lease Time
•
The Client Lease Time is the amount
of time a network user will be allowed connection to
the Router with their current dynamic IP address. Enter
the amount of time, in minutes, that the user will be
“leased” this dynamic IP address. The range is 5-43,200
minutes. The default is
1440
minutes.
Dynamic IP Range Start/End
•
Enter a starting IP
address and ending IP address to create a range of
available IP addresses. The default range is
100-149
.
(Make sure the Router’s LAN IP address is not in this
dynamic IP range.) For example, if the Router uses the
default LAN IP address,
192.168.1.1
, then the starting
value must be 192.168.1.2 or greater.
DHCP Relay
The DHCP Relay mechanism allows DHCP
clients and the DHCP server to be located on different
networks. The DHCP clients will send DHCP discover
broadcast packets to get IP addresses from the DHCP
server, and the Router will act as a DHCP Relay agent and
send DHCP unicast packets to DHCP server. To use the
DHCP Relay function, select
DHCP Relay
. The DHCP server
function will be automatically disabled. Then configure
the DHCP Server IP Address setting.
DHCP Server IP Address
•
Enter the IP address of the
DHCP server.
