Setup
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.
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.

on its MAC address.

Block MAC address on the list with wrong IP address To
block traffic from devices with MAC addresses on the Static
IP list but using the wrong IP addresses, select this option.
It prevents users from changing device IP addresses
without your permission.
Block MAC address not on the list To block traffic from
devices using dynamic IP addresses, select this option. It
blocks all devices with MAC addresses not listed on the
Static IP list.
DNS
DNS Server You can assign DNS server(s) to the DHCP
clients so the Router will use the DNS server(s) for faster
access to functioning DNS server(s). Enter the IP address
of at least one DNS server.
WINS
WINS Server Windows Internet Naming Service (WINS)
is a service that resolves NetBIOS names to IP addresses.
WINS is assigned if the computer (DHCP client) requests
one. If you do not know the IP address of the WINS server,
keep the default, 0.0.0.0.
