IMPORTANT:
Bridged mode is intended for testing purposes only, as in WT-062 (ADSL), BER (Bit Rate
Error), or industry standard performance tests. When routed mode is disabled, the 2Wire gateway can no
longer be managed via CMS, and any DSL connection will require an external PPP connection (via software
of third-party hardware). It is strongly recommended that you disable routed mode
ONLY
if you thoroughly
understand the ramifications of doing so.
To operate the gateway in bridged mode:
1.
Deselect the
Enable Routing
checkbox.
2.
Click the
Submit
button.
Most gateway features are now disabled, including firewall and stateful packet inspection, DHCP
, NAT, DNS,
PPP
, and remote management. The gateway no longer functions as a gateway and is, in effect, a multi-
protocol (Ethernet, wireless, and USB) bridge.
Computers connected to the 2Wire gateway will retain the IP address assigned by the gateway’s DHCP
server until a new IP address is obtained from an alternative DHCP server, or is manually assigned.
To re-enable routed mode:
1.
Configure the computer’s IP address to work on the same subnet as the gateway.
a.
From the Windows desktop or the Start menu, right-click the My Network Places icon, then left-click
Properties
.
b.
Right-click the icon that represents the network connection to the gateway, and
left-click
Properties
.
Note:
When routing is disabled the gateway’s local IP address is set to 172.16.0.1/16.

c.
Click Internet Protocol (TCP/IP), then click the
Properties
button.
d.
In the General tab, click the
Use the following IP address
radio button.
In the IP address field, enter an IP address between 172.16.1.1 to 172.16.1.32. In the Subnet
mask field, enter 255.255.0.0. In the Default gateway and Preferred DNS server fields, enter
172.16.0.1.
e.
Click
OK
.
f.
If required, reboot the system for the changes to take effect.
2.
Attach the computer to the Local Network port of the 2Wire gateway.
3.
In the Web browser address bar, enter 172.16.0.1/management.
4.
Click Configure Services.

5.
Click the
Enable Routing
checkbox.
6.
Click the
Submit Settings
button.
The gateway PPP
, routing, and TCP/IP functions are now re-enabled, and the Local Network LED will turn
Green. The computer can now be reset to a DHCP-assigned IP address, or left to obtain it statically.
Changing Timeout Parameters
By default, TCP and UDP are configured to timeout in 1,440 and 10 minutes, respectively. You can change
the parameters by entering different values in the TCP Timeout and UDP Timeout fields, and then clicking
the
Submit
button.
Enabling Broadband Status Notification
To receive a notification message that the gateway has lost broadband connectivity and cannot access the
Internet, check the
Enable
checkbox.
Enabling Missing DSL Filter Notification
To receive a notification message that the gateway has detected a missing DSL filter, check the
Enable
checkbox.
Enabling SIP Application Layer Gateway
To enable the SIP ALG on the gateway firewall, check the
Enable
checkbox.
Changing the Upstream MTU
The MTU (Maximum Transmission Unit) is the largest size packet or frame, specified in octets (eight-byte
bits), that can be sent from a computer to the network. The 2Wire gateway’s MTU varies, depending on the
connection type used (for example, PPP or direct IP).
To change the gateway’s upstream MTU:
1.
In the Force Upstream MTU field, enter the value specified by the service provider.
2.
Click the
Submit
button.
Note:
This field will display only if the CMS organization has the Broadband Status Notification
feature enabled.
Note:
This field will display only if the CMS organization has the Missing DSL Filter Notification
feature enabled.

Advanced - Static Routes
The Advanced - Static Routes page allows you to manually configure static routes that specify the
transmission path data must follow between devices on the gateway network.
Figure 49. MDC Advanced Static Routes Page
To define a static route:
1.
In the Subnet IP field, enter the IP address of the network to which you want to configure a static route.
2.
In the Subnet Mask field, enter the subnet mask of the destination network.
3.
In the Gateway IP field, enter the IP address of the router for the specified subnet.
4.
Click the
Add
button.
Note:
To access this page, your organization must have the Remote Management feature
enabled. If the feature is not enabled, an error message will display when you click the link to
access this page.
