Scenario 2: Bridged Connection to ISP
In this configuration, your ISP requires you to configure a bridged
Internet connection. For a bridged internet connection, the WAN
interface must be bridge-enabled. The configuration would have
these features:
f A bridge-enabled EoA WAN interface. Bridged IP
connections must use an EoA-type WAN interface. An IP
address may or may not be specified for the interface.
Note that even when the device communicates with your
ISP as a bridge, its Ethernet interface must remain IP-
enabled to allow you access to the Web Configuration
program through your Web browser. The Ethernet Modem
Router can also continue to provide certain IP-based
services to your LAN such as DHCP server and DNS relay.
f Both the LAN (eth-0 and/or usb-0) and the WAN interfaces
(eoa-0) are enabled for bridging. See “Making Interfaces
Bridgeable (Bridge-Enabled)” on page 79.
f The bridging service is enabled. See “Enabling Bridging
f The ISP should provide setup instructions for the LAN
PC(s), which may involve installing software to enable
logging in to their servers (called a "PPPoE client"). The
PC's gateway IP address should be configured as the IP
address of the ISPs access server.
In the System View page in the Home tab, the Mode field will reflect
Routing and Bridging. Although you are exclusively using a bridging
connection to your ISP, the device recognizes at least one IP-
enabled interface (eth-0), and therefore regards the device as
capable of both routing and bridging.
