DHCP Server:

If enabled, the modem router will work as a DHCP server, which provides the

TCP/IP configuration for all the PC(s) that are connected to it on the LAN.



Start IP Address:

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

Because the default IP address for the modem router is 192.168.1.1, the default Start IP

Address is

192.168.1.100

, and the Start IP Address must be 192.168.1.100 or greater, but

smaller than 192.168.1.254.



End IP Address:

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

The End IP Address must be smaller than 192.168.1.254. The default End IP Address is

192.168.1.254

.



Lease Time:

The Leased Time is the amount of time in which a DHCP client can lease its

current dynamic IP address assigned by the modem router. 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.



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.
