Step 2: Allocate Public IP Addresses to the LAN Clients
This step requires that all network devices that you wish to configure with a broadband IP  address be turned
on and connected to the 3700HGV-B. Devices should be configured to use their DHCP client f or obtaining
an IP address, although this is not an absolute requirement as identified below.
Once the gateway is configured to use multiple broadband IP addresses, network devices can  be configured
for one of three modes. Access the Address Allocation page of the MDC to select the desire d option (Figure
2) for each LAN device. This information can also be set by clicking the EDIT ADDRESS ALLO CATION button on
the Home Network - Advanced Settings page.
• Mode 1: DHCP Private Network. The network client is given a private IP address on t he private network
(Default is the 192.168.1.0 network). This is the normal mode of operation for all LAN dev ices by
default (with or without the use of multiple broadband addresses.)
• Mode 2: Public Fixed Network. The network client is given one of the currently avai lable broadband IP
addresses. The address may change as the IP address lease is renewed, but will always come  from the
pool of available broadband IP addresses.
• Mode 3: DHCP Fixed Address. The network client is permanently assigned one of the b roadband IP
addresess. The address will not change until the gateway is reconfigured via the Address A llocation
page. This will be the most common configuration for publicly accessible network devices.
In all the above cases, the network devices should be configured to enable their DHCP clie nt. From this
point on, the IP addresses for these LAN devices are managed by the 3700HGV-B. However, if  DHCP is
unavailable or its use undesirable, devices can be configured (hard-coded) with a static I P address.
For devices in the Private Network (NAT), the proper range must be used. The default range  is 192.168.1.0,
so the network device may statically use 192.168.1.1 through 192.168.1.64, inclusive. Devi ces assigned
with these addresses act as if they were assigned an IP address (Mode 1 above).
For devices using the Public Network addresses, simply configure the device to use the IP  address (subnet
mask and default gateway) as assigned by the ISP. The gateway will automatically detect th e usage of a
broadband IP address on the LAN network and correctly route the return traffic to the appr opriate LAN
device. Once a broadband IP address has been detected by the gateway as being statically c oded on the
device, its entry in the Address Allocation page will no longer be displayed.
Note: The ability to use DHCP in assigning WAN addresses to LAN devices is different from  how
some other routers operate. These other routers usually require that the address be hard c oded
on the LAN device.
Upon successful configuration of the gateway, refresh the IP address of the network device  (this may require
restarting that device). It should now have the desired public, or private, IP address ass igned by the
3700HGV-B. Confirm proper configuration by attempting to access the public Internet.>

However,if  DHCP is unavailable or its use undesirable
devices can be configured (hard-coded) with a static IP address.
