

Start IP Address:

Enter a value for the DHCP server to start with when issuing IP addresses.

The default Start IP Address is

192.168.1.100

.



End IP Address:

Enter a value for the DHCP server to end with when issuing IP addresses.

The default End IP Address is

192.168.1.199

.



Lease Time:

The Leased Time is the amount of time in which a network user will be allowed

connection to the modem router with their current dynamic IP address. Enter the amount of

time, in hours, then the user will be “leased” this dynamic IP address. After the dynamic IP

address has expired, the user will be automatically assigned a new dynamic IP address. The

default is

1440

minutes.



Default Gateway -

(Optional.) It is suggested to input the IP address of the LAN port of the

modem router. The default value is 192.168.1.1.



Default Domain -

(Optional.) Input the domain name of your network.



Primary DNS -

(Optional.) Input the DNS IP address provided by your ISP or consult your

ISP.



Secondary DNS -

(Optional.) Input the IP address of another DNS server if your ISP provides

two DNS servers.



DHCP Relay:

Select

Relay

, then you will see the next screen, and the modem router will work

as a DHCP Relay. A DHCP relay is a computer that forwards DHCP data between computers

that request IP addresses and the DHCP server that assigns the addresses. Each of the

device's interfaces can be configured as a DHCP relay. If it is enabled, the DHCP requests

from local PCs will forward to the DHCP server runs on WAN side. To have this function

working properly, please run on router mode only, disable the DHCP server on the LAN port,

and make sure the routing table has the correct routing entry.
