TR-064 is a LAN-side DSL Gateway configuration specification. It is an extension of UPnP. It

defines more services to locally manage the Netopia Gateway. While UPnP allows open

access to configure the Gateway's features, TR-064 requires a password to execute any

command that changes the Gateway's configuration.

TR-064 is enabled by default. To

disable

it:

•

Uncheck the

checkbox, and click the

button.

•

The Alert icon will appear in the upper right corner of the web page. Click the Alert icon,

and when prompted, click the

link.

The Netopia Gateway can be used as a bridge, rather than a router. A bridge is a device

that joins two networks. As an Internet access device, a bridge connects the home com-

puter directly to the service provider’s network equipment with no intervening routing func-

tionality, such as Network Address Translation. Your home computer becomes just another

address on the service provider’s network. In a DSL connection, the bridge serves simply

to convey the digital data information back and forth over your telephone lines in a form

that keeps it separate from your voice telephone signals.

If your service provider’s network is set up to provide your Internet connectivity via bridge

mode, you can set your Netopia Gateway to be compatible.

Bridges let you join two networks, so that they appear to be part of the same physical net-

work. As a bridge for protocols other than TCP/IP, your Gateway keeps track of as many as

512 MAC (Media Access Control) addresses, each of which uniquely identifies an individual

host on a network. Your Gateway uses this bridging table to identify which hosts are acces-

sible through which of its network interfaces. The bridging table contains the MAC address

of each packet it sees, along with the interface over which it received the packet. Over

time, the Gateway learns which hosts are available through its WAN port and/or its LAN

port.

When configured in Bridge Mode, the Netopia will act as a pass-through device and allow

the workstations on your LAN to have public addresses directly on the internet.

☛

NOTE:

In this mode the Netopia is providing NO firewall protection as is afforded by

NAT. Also, only the workstations that have a public address can access the

internet. This can be useful if you have multiple static public IPs on the LAN.

Bridging per WAN is supported in conjunction with VLANs – individual WANs can be bridged

to the LAN only if the WANs are part of a VLAN. (See

“

VLAN

” on page

106

for more infor-

mation.) The capability to bridge individual VLANs is supported only if the underlying encap-

sulation is RFC1483-Bridged (ether-llc).

Configure

Configuring for Bridge Mode

1.

Browse into the Netopia Gateway’s web interface.

2.

Click on the

button in the upper Menu bar.

3.

Click on the

link.

The LAN page appears.

4.

In the box titled LAN IP Inter-

face (Ethernet 100BT):

Make note of the Ethernet IP Address and

subnet mask.

You can use this address to access the

router in the future.

5.

Click on the

link in the left-

hand links toolbar.

6.

Under the heading of Services, click

on the

link.

104

The Ethernet Bridge page appears.

The appearance of this page varies,

depending on your Gateway’s inter-

faces.

7.

If available:

a. Check the

Enable Bridging on Port

selection. (This may be Always On.)

b. Click

.

8.

If you want the Gateway to do

both bridging and routing, check

the

checkbox.

When this mode is enabled, the Gateway will appear to be a router, but also bridge traf-

fic from the LAN if it has a valid LAN-side address.

9.

Check the

checkbox.

The window shrinks.

b. Click

.

At this point you should be ready to do the final save on

the configuration changes you have made.

The yellow

Alert

symbol will appear beneath the Help button

on the right-hand end of the menu bar.

10.

Click on the Alert symbol and you will see whether

your changes have been validated.

If you are satisfied with the changes you have made, click

in the Save Database box to Apply changes and restart Gateway.

You have now configured your Netopia Gateway for bridging, and it will bridge all traffic

across the WAN. You will need to make configurations to your machines on your LAN. These

settings must be made in accordance with your ISP. If you ever need to get back into the

Netopia Gateway again for management reasons, you will need to manually configure your

machine to be in the same subnet as the Ethernet interface of the Netopia, since DHCP

server is not operational in bridge mode.
