Network Address Server Settings (DHCP)
The Network Address Server Settings (DHCP) allow you to configure the residential
gateway’s Dynamic Host Configuration Protocol (DHCP) server function. The
residential gateway can be used as a DHCP server for your network. A DHCP server
automatically assigns an IP address to each computer on your network. If you
choose to enable the residential gateway’s DHCP server option, make sure there is
no other DHCP server on your network.

Configure the following parameters per the guidelines provided:
Starting IP Addres
s
—
Enter a value for the DHCP server to start with when
issuing IP addresses. Because the gateway default IP address is
192.168.1.1,
the Starting IP Address must be 192.168.1.2 or greater, but smaller than
192.168.1.253. The default is 192.168.1.64.
Ending IP Address
—
Enter a value for the DHCP server to end with when
issuing IP addresses.. The default is 192.168.1.253.
Client Lease Time
—
The amount of time a network device is allowed
connection to the gateway with its current dynamic IP address. Enter the
number of minutes that the device is “leased” this dynamic IP address. After
the time is up, the device is automatically assigned a new dynamic IP
address. An entry of -1 means inifite lease. The default is 1440 minutes.
DNS Proxy (Advanced View)
—
The Domain Name System (DNS) is how the
Internet translates domain or website names into Internet addresses or URLs.
To use DNS Proxy, keep the default, Enable. Otherwise, select Disable.
Static DNS 1,2, 3 (Advanced View)
—
These entries are valid only when the
DNS Proxy option is disabled. At least one DNS server IP address is
provided by your ISP. You can enter up to three DNS server IP addresses
here. The gateway uses these for quicker access to functioning DNS servers.
WINS (Advanced View)
—
The Windows Internet Naming Service (WINS)
converts NetBIOS names to IP addresses. If you use a WINS server, enter that
server IP address here. Otherwise, leave this field blank.
Domain Name (Advanced View)
—
Enter the domain name of your local
network.
Reserved IP List (Advanced View)
—
Enter the IP addresses you want to
reserve, so they will not be leased to DHCP clients.
