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.
1
Select
Enabled
for the DHCP Server field to allow
the server to automatically
assign an IP address to each computer on your network for you. Unless you
already have, Cisco recommends that you keep the default,
Enabled
.
2
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.

DHCP Option Value
This value is stored as binary string on the Gateway.
For some DHCP options, the user can enter a
native format such as an IP
Address or integer; for others, the user must enter HEX strings to represent
binary string of a DHCP option. (No check is performed on these values.)

Advanced DHCP Settings (Advanced View)
Complete the following steps to configure the Local Network DHCP Settings
available from the Advanced View:
1
Navigate to the Advanced DHCP Settings.
Path
: Setup > Local Network > Advanced View
2
Select the desired option for the the
DHCP Address
, which
defines the DHCP
address allocation method:
Use DHCP Pool
This option assigns local IP addresses from the DHCP
pool you have defined. This is the default option for this parameter. Skip to
step 5.
Use WAN Subnet
Select this option to have the local network devices share
the WAN subnet address. In this pass-through mode, the local computers get
WAN-side IP addresses. They bypass NAT and are visible on the service
provider’s network. However, these computers can still communicate with
other computers that are allocated private IP addresses. Continue with step 3.
Share WAN IP
Select this option to have a local network device share the
WAN IP address. In this mode, which is also known as super-DMZ mode, a
single computer bypasses NAT. You can specify the computer’s MAC
address in the
MAC Address
field.
Continue with step 3.
3
If you selected Use WAN Subnet or Share WAN IP, select the appropriate WAN
IP connection to use from the
WAN IP Interface
drop-down menu.
4
If you selected Share WAN IP, enter the MAC address of the local network
device in the
MAC Address
field.
5
In the
Lease Time
field, enter the number of seconds you want the local network
device to lease the WAN IP address.
