Configuring LAN Devices
Typically, your Internet ser vice provider automatically assigns and configures a dynamic IP address when 
your system connects to the Internet. Businesses or power users may use a static address enabling them 
to run advanced ser vices such as Internet servers and video conferences. The availability of static IP 
addresses is usually an additional ser vice offered by ser vice providers. In addition, changes from the 
default behavior of the gateway for private IP addressing may also be used by some users. 
Configure these settings ONLY if you are ver y familiar with computer networking technologies. This section 
provides instructions to set up your private network that includes: 
 Configuring additional network on page 80
 Configuring DHCP on page 81
 Allocating IP addresses on page 85
 Selecting DSL lines on page 88

Configuring your LAN Publicly Routed Subnet
You can create a local network that has broadband network-accessible IP addresses by creating a route 
from the Internet to the specified public network. This feature is typically used in conjunction with 
broadband ser vice that provides a range of available IP addresses. Once enabled, the public IP addresses 
can be assigned to local computers. 
1.Open a Web browser and enter http://gateway.2Wire.net to access the 2Wire i3812V user interface, the 
Home page opens.
2.Click , the Broadband Status page opens.
Note: Set up your LAN publicly routed subnet first if you want to use the 
public address with your DHCP configuration.

3.Click Link Configuration; the following page opens. 
4.Change the Upstream Maximum Transmission Unit (MTU), if necessar y. 
5.Select Enable to add a secondar y network to the broadband WAN interface. 
6.Enter information in the following fields:
−
Router Address: Enter the router address (this is the router address from the secondar y subnet 
provided by the ser vice provider). 
−
Subnet Mask: Enter the subnet mask (this is the router mask from the secondary subnet provided 
by the ser vice provider).
7.Select the Auto Firewall Open checkbox if you want to automatically disable the firewall for all devices 
using addresses from this subnet. (By default, the firewall protection is enabled.) 
8.Click Save.
Configuring DHCP
Dynamic Host Configuration Protocol (DHCP) allows for dynamic allocation of network addresses and 
configuration to newly attached hosts. The i3812V can be both DHCP client and DHCP server. The i3812V 
acts as a client when it communicates to your ser vice provider over the Internet using the IP address. For 
Note: You can individually enable the firewall on a per device basis (refer to 
Allocating IP Addresses on page 85) or on a per application basis using the 
Firewall option (refer to Allowing all Applications (DMZplus) on page 49).

this communication, you cannot modify the related DHCP settings. The i3812V is a DHCP server to your 
local network devices such as the i38HG and computers connecting to it. 
To configure the default DHCP information used as a local ser ver: 
1.Open a Web browser and enter http://gateway.2Wire.net to access the 2Wire i3812V user interface; the 
Home page opens.

4.Click DHCP; the DHCP Configuration page opens. 
5.Select Configure manually if you want to set up a range for the DHCP address IP pool. 
6.Enter information in the following fields:
−
Router Address: This is the IP address of your i3812V used for all communication on your local 
devices. 
−
Subnet Mask: This is the subnet mask used for all communication on your local devices (the default 
is 255.255.255.0). 
−
First DHCP Address: The first IP address in the DHCP address pool that you will be distributing over 
the private network.
−
Last DHCP Address: The last IP address in the DHCP address pool that you will be distributing over 
the private network.
7.Enter a numerical value in the DHCP Lease Time field. This value represents the number of hours you 
can use the assigned IP address before the DHCP lease expires.
8.Select a public IP address pool that is assigned via DHCP on the local area network.

Allocating IP Addresses
You can allocate specific IP addresses to devices that are running in the DHCP mode, and map devices to 
particular static (public) or private IP addresses. For Internet public hosting of application or servers 
associated with static addresses, you can map a device to a specific public fixed IP address or to the next 
unassigned address from the public pool. The default public IP device mapping is to the Router WAN IP 
address. 
1.Open a Web browser and enter http://gateway.2Wire.net to access the 2Wire i3812V user interface, the 
Home page opens. 
Note: Change to the Public IP address only when used in conjunction with 
DMZplus or secondary subnet functionality that allows you to have public IP 
addresses routed through the device. 
Note: Alternatively, you may also statically configure public or private IP 
addresses on the device themselves. Statically addressed device addresses 
override settings made on this page.
